Java Video Tutorial
Here I begin what will be a massive Java Video Tutorial. I start with all you need to start writing Java programs.
I then cover just about anything you’d want to know about Javas primitive data types. I cover declaration statements, expression statements, all the types and how to convert them.
This tutorial starts out slow, but by the end you will be a Java expert! Make sure you print out the code below to help you learn easier.
I promise watching this Java video tutorial from beginning to end will teach you everything there is to know about Java. I hope you enjoy it.
If you like videos like this tell Google
To make me extra happy, feel free to share it
Code From Video
// Here I'm defining a new class (Blueprint) named HelloWorld
// public tells Java that this should be available to all other classes
// classes are blue prints used to design objects that contain attributes (variables) and methods (functions)
// HelloWorld is just what you named your program. That allows you to reference it later
// { is the opening brace that surrounds the code used by HelloWorld
public class HelloWorld
{
// public allows other classes to use this function
// static means that only a class can call for this function to execute
// void states that this function doesn't return any values after it is done executing
// main is required in every Java program. This function is always executed first
// Every main function must accept an array of string objects
// Class variables must start with static if you want to access them with any other methods in the class
static String randomString = "String to print";
// Constant variables are defined with the word final
static final double PINUM = 3.1415929;
public static void main(String[] args)
{
// System.out is an object that outputs information
// println is a function that prints to the screen what ever you provide between braces
// "Hello World" is a string of characters. Strings must be surrounded with quotes
// Every statement ends with a semicolon ;
System.out.println("Hello World");
// Variable names are case sensitive. Age is not the same as age.
// Variables must begin with a letter and contain numbers, _, or $
// You must declare all variables before you can use them with a data type
/* You can use any variable name except for
* abstract continue for new switch assert default goto package synchronized
* boolean do if private this break double implements protected throw
* byte else import public throws case enum instanceof return transient
* catch extends int short try char final interface static void
* class finally long strictfp volatile const float native super while
*/
// This is a declaration statement
// integerOne is a local variable to the main function. It can only be accessed in main
int integerOne = 22;
int integerTwo = integerOne + 1; // This is an expression statement
// White space has no meaning in Java, aside from variables and keywords

* There is no reason to parse a Character
*/
}
// You must provide a closing brace } so Java knows when the function has ended

awesome tutorial, please provide more videos as soon as possible..
Next week I plan to make a video a day while on vacation. It should be fun, or at least educational 🙂
Your tutorials are terrific and most inspiring. It would be most beneficial to follow the videos with either subtitles or a transcript of the accompanying lecture (audio input from you) as I am severely hearing impaired in both ears. I hope you don’t mind this humble request as your comments in the code for each lesson are usable during revision.
Thank you very much 🙂 I have captioning on YouTube, but I don’t know how well it works. I’ve recently been asked to translate the videos into other languages, but I’m not sure how to do that or how to make the captioning better. I’ll look into whether YouTube allows me to change that. Thank you for the request and I’ll see what I can do
Thank you for your helpful & continued advice. You are a gem to look into this request further. I’ve tried the caption option on YouTube, unfortunately it doesn’t work at all for me. Apart from resorting to your on line help with understanding the code in the brilliant lessons, would it be possible to increase & expand on your commented explanations in the comments in the code for each lesson. I remain greatful for your most kind consideration of my request. Thank you very much.
I could put a translator on my site if you think that would help? The only reason why I haven’t is because I thought Google automatically translates sites into any language. I’m not sure if they do that in your country though. I’m sorry, but I’m not very well traveled and know very little about other countries. If there are any tools I can add to help you I definitely will add them
I’m from the London, UK and can only use English, but would much appreciate any help with computerspeak, as it can be as daunting as ancient Greek! On a tangent, may I please request your learned advice and help about availability of Video tutorials for computer hardware? I look forward to hearing from you. Thank you very much, once again.
Are you looking for a tutorial on simulating speech? I’d love to do something on that topic. Image recognition would be more exciting yet and I plan on covering that in the future when I explore AI. I have been planning a tutorial on electronics for over a year. I was going to start of with basic components and work my way up into a functioning machine with an OS and everything. I just haven’t been able to fit it in. It doesn’t seem like many people are interested in that for some reason? I have all of the equipment and hope to cover that soon
I wish to thank you for your continuing and enthusiatic help, encouragement and inspiration with regards to my requests for help with image recognition and simulating speech. It is so wonderful that this is associated with your own exploration of AI. I must say that I am really looking forward to your planned tutorial on electronics, which would work all the way up into a functioning machine with an OS. I do hope you get the required time and resources to fit it in to your demanding schedule. I hope that this endeavour appeals and more people express their interest. In the meanwhile, thanks for all your well intended help.
Thank you for the kind words 🙂 I really want to cover electronics and will get to it soon. Sometimes I get a bit overwhelmed by requests. Always know that I’m doing my best to fulfill everyones requests.
Thank You Sir!!!! for such a g8 tutorial!!!!! terrific!!!
You’re very welcome 🙂 I’m very happy that you enjoyed it!
thank you very mutch derek
this new serie came in a right time
after covering almost the web languages programing you made the right choise to move to java.
so thank you derek see you in the next tutorial
Yes I’ve covered most everything in regards to web specific languages. I do want to go back and cover Ruby. I’ll probably do that after I’m done with Java. Then I’m going to start covering other areas of knowledge like I mentioned before. I hope you like the new direction
Hello, your tutorials are as always interesting. I dont know my question is related to java or not but just wanted to ask whether u know how to create something like this website dollar2rupee.net, its a dollar to rupee exchange rate website. Can you help out. Thanks
Thank you 🙂 A tool like that is easy to make with JavaScript. I teach you most of what you need in this JavaScript Tutorial You may have to look at the others that proceed it depending on how good you are at JavaScript. I hope that helps
Thank you for your response, if possible try to make a tutorial series for advance java also, i never found tutorial series for this anywhere.
What do you want to see me cover in regards to advanced java? If you give me a list I’ll incorporate it into the tutorial. Thanks
Hello, sorry for answer in old topic. I would like to see turtorials about Hibernate/Spring. But first of all about JUnit, and testing.
Thanks for being my teacher ! Have a nice day.
Those tutorials are in the works. I will definitely cover them as soon as I finish up Android.
Awsome, I am really waiting forward for them 😀 regards from Poland.
Hi,
I installed Eclipse as shown in yor tutorial. When I want to create a new file.java I cannot save it. I do not see any path as in your tutorial. Do I have to create a project first or did I do something wrong with the settings? Thanks.
Did you create a new workspace when you first started Eclipse? You also have to make sure Java is highlighted in the upper right hand corner in Eclipse. I have everything saved in the Package Explorer – src – default package folder. I hope that helps
Thanks for your reply. It actually worked when I made a Java Project first. With this I was able to create and save the java file. I did create a workspace.
Great! I figured it was just something silly
Great tutorial on java! Can you make a tutorial on else, if, for while,arrays and loops.
Thanks
Absolutely I’ll cover conditional statements, loops, OOP, Arrays, Strings, Collections, functions, Threads, Networking, regex, Swing, Streams, Databases, Servlets, etc. It is going to be a huge tutorial 🙂
I am taking Java programming in school and I want to learn the basic concepts before I start taking my classes. Looking forward to the videos.
Thanks!
I’ll cover more than just the basics. I plan to cover conditional statements, loops, OOP, Arrays, Strings, Collections, functions, Threads, Networking, regex, Swing, Streams, Databases, Servlets, etc.
I hope you find them useful. They start off kind of boring, but get interesting very quick
if possible please provide tutorial on servlet and jsp.
I will cover servlets and a bunch of other things in regards to Java. I always do my best to create complete tutorials
Hey,
These tutorials are very helpful.. I will appreciate if you could upload tutorials for JSP, Servlets, Spring and Hibernate…
Thanks !!!
I plan on making many more java videos. I’m glad you like them. Java is kind of a hard language to teach. I’m doing my best
i have a question, final keyword is used to make something constant, ie.(we cannot change it), but what is this mean that “we cannot change it” if i change the value of the final variable, in the program/code, i can do that, so what is “we cannot change the value of final variable”.
You can’t change a final variable if it is a primitive data type. You could however change the value of a non-primitive. The only thing that’s final about a non-primitive is its reference in memory. I haven’t really gotten to advanced stuff like this, so if this doesn’t make sense stay tuned for the future videos
okay…thanks…
It would be great if you could set some small assignments in Java so people can test their skills.
Thanks
Java beginner
The best advice I can give you is to study the video and then try to recreate everything out of your head. I’ll look into making assignments because I’ve received that request many times.
Please admin i am studying java
and just asking about the applications which contains big numbers
it could not be defined in int , long or double
is there is a(BigIntegar) in java or how can i?
thank you very much for your help
You are looking for BigInteger and BigDecimal. Click the links for more information on them. I hope that helps
Great videos! I enjoyed your SQL Video’s they helped me get a B+ in my last class. Now I am watching your Java series to supplement my reading.
Great I’m glad you like them. I’m making a pretty neat Java tutorial that shows you how to load SQL query results into a JTable. It is going up today
i love it
The best tutorial channel on YouTube.
I have a question though. My heart and soul is broken with Eclipse.
I’m trying to run the HelloWorld code in Eclipse and all I get is a “Launch Error – Editor does not contain a main type”.
Please help me before I throw my laptop out the window!
Gary.
Thank you 🙂 I made a tutorial on how to install Eclipse and Java here Install Java 1.7 Eclipse
As per your error, you probably saved the program in the wrong folder. You need to have the Package Explorer panel open in Eclipse. If you don’t see it do this: Click Window – Show View – Package Explorer
Now that you have it on your eclipse screen click on the folder it has in it. You’ll see another folder named src. Inside of src, you’ll see default package. Save your java code in default package.
If you don’t see anything in Package Explorer, right click in Package Explorer and Click New Project.
That should do it. If not tell me
Derek
Hi Derek excellent explanation.I was not having an idea in programming lang.after wacthing your series i am pretty much aware of the lang.great work derek.
Thank you. Always feel free to ask any questions and to leave tutorial requests
Hello Team,everything cant be spoon feeded.you all must start practicing wat derek has taught.his tutorials is sufficient for a person to become a good programmer.you people have to give your effort to after watching his video series.
I am new to this so i dont know which program to download????
I use Eclipse Classic to write Java programs in this tutorial. It works and looks the same on every OS.
thanks
You’re very welcome
Great Videos! I watched all of the java videos you posted. Could you please post some videos for replacing token values in the file1.properties and file2.properties? i.e
HOST_NAME = ;
DB =
I cover buffered reader and writer in Java Video Tutorial 32 and binary streams in Java Video Tutorial 33.
I’ll be covering J2EE and Java networking very soon in their own tutorials. Thanks for the request 🙂
Another question, I created a class and later deleted it along with the folder in the windows’ explorer. Now it give me error whenever I try to create that class. It says class type error when I try to give the name to that class. How do I fix this problem. I’m using eclipse.
Also, for last comment less than or greater than symbol removed the information that I typed for dollarsymbolHost eq.to lt symbol-replace this token-greater than symbol;
You have to replace the class to get your program to work. Maybe it is still in the recycle bin?
Thanks for the tutorials. I have watched some of your other videos, but i have just started watching this series. Still these seem to be some of the most well made video tutorials out there. thnx for all the work i’m sure u put into these.
You’re very welcome 🙂 I guess after making almost 500 videos I’m getting better. I wish i would have incorporated testing into the videos from the beginning like the khan academy does. I’m always working to make them better and I hope they continue to live up to your kind words. Thank you for the support
After about two weeks of web surfing for concise to-the-point tutorials I discovered your videos on YouTube. I watched a majority of your Python 2.7 tutorials and can say that 50% of my knowledge was from those videos (the other 50% acquired over time and through my job). The speed and clarity of your videos stuck in my mind, and when I decided a few days ago I’d like to learn Java, I didn’t think twice about where to begin. Nothing else compares to these videos. You are the Master Tutor!
Thank you so much for taking the time to offer these free videos. I have found that I absolutely love programming, and am excited to learn more and more, most of which will be with your videos. Don’t stop!
Hi Justin, I’m very happy that you enjoy my videos. Thank you for taking the time to say you like them. I have many more in the works. I recently stopped because I have a terrible cold, but I’ll start making them again next week. Always feel free to ask questions.
Derek
To cast to other primitive types just proceed with the conversion to type
ie (byte) (short) (long) (double)
(float) & (boolean) & (char) don’t work.
(char) stays as a number instead of a character
what do you mean by float, boolean and char not work?
Do you mean by casting double to float, boolean and char is not working or for any type to float, boolean and char also not working?
I have tested in following way and it shows that float, boolean and char can be casted. Would you mind to explain further?
double aDoubleValue = 3.1456789;
float doubleToInt = (float)aDoubleValue;
System.out.println(doubleToInt);
// It displays 3.5679
double aDoubleValue = 3.1456789;
float doubleToInt = (float)aDoubleValue;
System.out.println(doubleToInt);
// It displays 3
double aDoubleValue = 3.1456789;
char doubleToInt = (char)aDoubleValue;
System.out.println(doubleToInt);
// It displays a question mark inside a box
Also, what do you mean by (char) stays as a number instead of a character?? can you provide some example?
Got a question: I was searching for the solution to the problem “(Counting occurrence of numbers) Write a program that reads the integers
between 1 and 100 and counts the occurrences of each. Assume the input ends
with 0.”
GOT this solution from a site … forgot the address
import java.util.Scanner;
public class OccurenceOfNumbers {
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
int[] counts = new int[100];
System.out.print(“Enter the integers between 1 and 100: “);
System.out.print(“\nEnter 0 to terminate the program and count numbers: “);
int number = input.nextInt();
while (number != 0) {
counts[(number – 1)] += 1;
number = input.nextInt();
}
for (int i = 1; i 0)
System.out.println(i + 1 + ” occurs ” + counts[i] + (
counts[i] == 1 ? ” time” : ” times”));
}
}
Please Sir can u explain me this part
int number = input.nextInt();
while (number != 0) {
counts[(number – 1)] += 1;
number = input.nextInt();
}
Why number = input.nextInt(); is done twice …. HELP!!!
nextInt() gets the integer entered on the keyboard.
while that number isn’t equal to 0
In the count array, in the index with a value 1 less then the number entered at the keyboard increment the value inside by 1
Ask for the next integer entered in the keyboard.
Does that help?
Thank you Sir ….. U are always ready to help …. Meet u when i again get stuck …. 😀
You’re very welcome 🙂
Hi – I need some help.
I have filled an array with random numbers, found the minimum value and know what position it is in. Now I need to switch the number in that position with the number in position 0, left sentinal. I don’t have my code with me to include here but is there anyway you can help me by explaining how I would go about this? Thanks – love your tutorial!
Here I cover Java sorting algorithms. I think this is the code you want:
int temp = theArray[indexOne];theArray[indexOne] = theArray[indexTwo];
theArray[indexTwo] = temp;
How do you recommend watching your videos and practicing to really understand, remember, and apply all of the stuff from the Java tutorial through Android, which you are doing now?
For best results
1. Print the code
2. Take notes on the code as you watch the videos
3. Make programs of your own using what you learn in each video
4. Send me any questions you have
5. Have Fun 🙂
Your videos are awesome. especially the way u cover the subject with in a given time is nice
Thank you 🙂
Thanku Sir , i m from india… a btech student… i m watching ol ur videos…i m vry vry thankful to u… ur videos r so helpful… its much much easy to learn java through ur videos…excellent teaching sir…Really awsme vids n codes… thanks again sir… 🙂
Thank you very much for the nice message 🙂 I’m very happy to be able to help you. I’m more popular in India then I am in my own country. That was very surprising. Always feel free to ask questions. I will do my best to help – Derek
First of all thank you so much for this wonderful job !!
I have a global request about all the java tutorials : Could you please make a post where I (and others) would be able to download an archive which would contains all the .java code ? ( Because yes I’m a little bored to copy-paste all files from the differents posts into notepad and save it as .java :p )
Thank you in advance !
PS : little advice : I looked for a guest book page where I could thank you but I didn’t find it, so maybe you could create one 😉
PPS : Sorry for my worst english !
bad* english :p
You’re very welcome 🙂 How would you want the download to be structured? Do you want every tutorial available in one download? Understand that I sometimes won’t have everything so heavily commented in the code I have on my computer because I never planned on doing that.
Your english is fabulous! As a person that grew up in a home were many languages were spoken, I’m aware of how hard it is to learn english. I’ll see what I can do about the guest book
Derek
Yes, that’s what I was thinking about ! Every classes files in a .zip or .rar 🙂 But if you don’t have the online code as files on your computer don’t worry, I’ll continue my copy-paste…
Thank you for my english 🙂
Ill see if I can dig up all that code. Sorry, I never expected to make so many videos on just java. Your English is perfect 🙂
Ok thank you. Do not apologize, I’m happy you made so many videos 🙂
Hi bro, your tutorials are fabulous, i have seen many tutorials online from premium faculties but not that impressing, your tutorials are excellent and brilliant, i dnt have words to praise your style.
Humble request to upload web services(soap,rest) in java tutorials.
Thanks so much
Thank you very much 🙂 I’m glad you are enjoying them. I will cover restful services in java after my Android tutorial, but I have been thinking about covering them either using Ruby, or PHP right now in the next few weeks. I need them for the Android tutorial. Tell me if you are in any way interested in that? Thank you
which book you will refer for Java ..thanks in advance..and yeah i love your videos..its easy to grasp
which book you will refer for Java ..thanks in advance..and yeah i love your videos..its easy to grasp – S
Head First books are my favorite
Hey your tutorials are amazingly good.. Can I start android development videos now or I need to get Java more.. Basically how much knowledge do I need to know to begin android development.. I am a computer engineering student and have programming experience
in c,javascript,php,phython
Thank you 🙂 I’d say give the Android tutorials a try and if you find that you need help I have a Java video tutorial that can help.
If you know all the other languages you shouldn’t have any trouble. Always feel free to ask questions
which basic laguages i need to know for android development.
which basic laguages i need to know for android development?
please reply
You basically just need Java for most everything. My Java tutorial will teach you everything you need. Parts 1 through 19, minus 8 and 10 will teach you all you need. Feel free to ask questions
Hi Derek,
First of all your tutorial is great I really like to appreciate
your effort you put in.
Derek can you provide all of us tutorial on collection and mapping in detail how it can be used to carry database and class object.
Thanks,
Shafin
Your video is awesome. I really appreciate you put your effort on it.
Can you provide tutorial on collection and mapping how it can be use with database object and class object, multithreading in detail.
Thank you very much 🙂 I cover most of these topics in this Java tutorial and also in my algorithms tutorials. I’m planning an advanced algorithms tutorial that should be out soon
nice vidios
keep moving forward
but please what theme did you use for the frames?
I use netbeans
Thank you very much 🙂 I’m using Eclipse in this series, but you can definitely use NetBeans
Derek Sir,
Great fan of yours. You teach better than any teacher I have come across. I want to make my fundamentals strong and clear Java certification by oracle. I believe watching your Java series and of-course advanced topic I can shape up my skills and take career to new height.
Any other MANTRA of yours is there then please teach us.
Great People Leave Great Stories Behind.
Thanks A LOT
Sameer
Thank you very much Sameer 🙂 You’re very kind. I’ll continue to do my best to cover these topics to the best of my ability. Thank you for stopping by my website.
Thank you very much for your tutorial ,really thank you
You are very welcome 🙂 Thanks for taking the time to tell me you liked it
Hi, your tutorials are splendid, but l have a little problem, when watching after some time its fade, and its hard for you to see what you are doing , l dont know why , my appeal is for you to correct that , thanks. Big up. Give u my thumb.
Thank you 🙂 It may help if you print out the code and take notes while pausing the video. That seems to help many people. Also since the notes are in your own words they tend to make you remember concepts later. I hope that helps.
Hi admin,
Thank you very much for all your videos, it is so informative for the beginners. I been watching your java,html,css and mysql video and lot that I can learn from your videos. I would also like to raise a request to please cover advance java video tutorials as well. I hope you would consider request in spite of your busy schedule.
You’re very welcome 🙂 What topics are you looking for in regards to advanced java tutorials? I have covered Design Patterns, Object Oriented Design, Refactoring, Java Algorithms and now Android with Java. I’m always interested in any other ideas for tutorials. Sorry if you missed these. My site isn’t that organized.
Thank you
Derek
Hi Derek,
I think the statement you have mentioned in this page in “Code from Video” section needs to be changed because this is correct only for static methods.
“// Class variables must start with static if you want to access them with any other methods in the class”
changed to
“// Class variables must start with static if you want to access them with static methods in the class”
Thank you for pointing that out. I’ll try to reword that
Derek,
I have been learning Java with heavy fire the past two months in aspirations to be a Java developer. I’ve read MIT courseware, several books on Java, and even downloaded a few “Learn Java” apps for quick reference while I am on my “Thinking Seat”! But no one else has broken down the language so eloquently as you have. I’m only on the 15th video so far, but you have explained everything perfectly. I have a greater understanding for Java now and hope to be through the videos by the end of the month!
YOU ARE AMAZING SIR!
David,
Thank you very much 🙂 I’m happy to hear that I was able to help so much. I continue covering java in my Design Patterns, Object Oriented Design, Refactoring, Java Algorithms and Android tutorials if you are interested in learning more. Always feel free to ask questions. I do my best to help.
Derek
Oh I will learn however much I can gobble up! I was a little stumped in regular expressions (especially the phone number part) but I managed to work my way through it. Will you be offering any tutoring in C++ as well? Would it be an easy jump after I’ve learned Java?
Yes I will definitely cover C++ after I finish covering C
Can u please do a tutorial on the seperate things you need to learn to make a minecraft mod??If it is not already there??
Here is a tutorial on setting everything up Minecraft Modding Guide.
This tutorial is pretty good after you learn the basics of Java.
how about scala,ruby on rails,opengl and system programming(linux commands,bash programming etc)is there any change to make tutorials for these languages?
I’m thinking about covering Ruby and OpenGL very soon. Thanks for the requests 🙂
Hi Derek,
I just wanted to know difference and how the jvm handles single quote(”) and double quotes(“”);
Thank you
Hi,
Use single quotes for characters and double quotes for Strings
Zillion of thanks for your great tutorial it is Time Saver + Money Saver = Make life Easy! but i have a small request….. I am just wondering can you make all those code in pdf format so we don’t need to print which saves money and tree 🙂 and more importantly we can upload it in Ipad and read when we watch the videos. Thanks once again. God bless you!
A Zillion you’re welcomes 🙂 I’m glad you enjoyed it.
Hello.
Can I have codes for all of your java videos, if its possible??
All the videos and the code is available on this one page Java Video Tutorial. I hope they help.
Hello Derek,
I have a question on servlet.
In the below web.xml content, Why / is used to mention login.jsp and loginpage. What is the meaning?
login
/login.jsp
login
/loginpage
Sham
/login.jsp
/loginpage
I’m sorry, but I’m not sure which specific tutorial you are referring to.
Derek,
I finished your Java videos back in October, and thanks to you I obtained my OCAJP Certification in November and looking for more I can do in the programming world. Thank you, sir!
Cheers,
Dave
Hi Dave,
Congratulations on getting the certification. I’m very happy if I was able to help 🙂
Derek
i want to learn java as i am beginner .. basic syntax how to make logics and how to use oop in java please help me..recommend me good book.so that i start learning fast & easily.
Q:;you make videos on books lesson?
The best book is Heads First Java. Feel free to ask questions. i do my best to help.
I want to learn java . tell me the book from which as a beginner i learn java,. Also oop in java …. i want to learn how to use 2 classes (1 with main method and other is simple)
The book everyone seems to like is Heads First Java. It is fun.
what can i do after watching your video…. i want to learn fast .
Is this possible that we can sort the CHAR in String?
I’m not sure what you are trying to do. Please provide an example and i’ll try to help
Sorry i want to combine two CHAR in one String Like this:
String randowString = "I'm a Developer";
String anotherString = "and name is bee ground";
String andanotherString = randowString + ' ' + anotherString;
System.out.println(andanotherString);
This is a Strings Variable. so i want to asked can we combine the CHAR like STEING
Check out my String Builder tutorial. I think that is what you need.
Mr Banas,
I am a freelance developer and I read your work just to learn something new or to refresh or for the fun. I give you a 10 🙂 and I like very much your philosophy of live. You have a big fan…
(I have just listened to you q&a session that I liked very much)
Could you notice the following ?
1)
// A char will except a number or a character surrounded by apostrophes
should be replaced by
// A char will accept a number or a character surrounded by apostrophes
2)
// A string conatins a series of characters
should be replaced by
// A string contains a series of characters
3)
// Every main function must except an array of string objects
should be replaced by
// Every main function must accept an array of string objects
See you next time ! Rudy (from Belgium)
Thank you 🙂 I corrected the errors. Now you know why I have never made a video on grammar.
By the way if you ever go in Belgium please tell me and I will buy you a drink 🙂 or something you like to reward you for the good work ! You deserve it !
Thank you 🙂 I’d love to go to Belgium some day. My wife would love it if I left the house every once in a while as well.
Can you recommend any programming books?also can you make any video to solve programming exercises?because mostly programmers
have no idea on problem solving.
The Heads First Java book is very popular. I made a tutorial on how to turn a problem into finished code. It is called Object Oriented Design. My UML tutorial might be very useful as well for that. I hope they help
I have a question, I have been watching your tutorials through and I have been deleting all the code when I went to the next video and realized that this code would be great for reference with the comments in the future because i’m new to java, so I was wondering if there was any way to download all of the files into eclipse and put them into a project so that when I am coding in the future I will have a big reference for the code.
Thanks – Bobby.
Yes I structured them so that they could be used as references. There really isn’t any way for me to set it up though so you can download everything directly into Eclipse. Sorry about that
Thank you, very clear and useful way of explaining the fundamentals!!
Thank you 🙂
Hi Derek Banas,Thanks a LOT for the videos and for the Great Explanation.You are our Life and Career Saver.Please keep up the Good Work.Please continue to work on these projects which help people like us.May GOD BLESS YOU… 🙂
Thank you for the kind message 🙂 May God bless you as well.
Hi I love your videos. But I have a question. If I learn Java, will it help me in making Android Apps? If not, what programming language is used to make Android Apps? Which software do you use to film your videos? Lastly, what programming language do you need to know to make IOS apps?
Yes Java is used to make Android apps. iOS is normally programmed using Objective C.
your java video tutorials are very good for newbie’s…can you please make some for java serial communication???
Thnx in advance….
Thank you 🙂 I’ll be making some new java tutorials soon.
Awesome tutorial, how do you know a lot about a lot?
Thank you 🙂 I actually don’t know a lot about many things. Almost everything I know has something to do with programming. I know almost nothing about pop culture, geography, history, etc. My wife laughs at me because I don’t know things like who the mayor or governor is 🙂
Hi! I am trying to build a web browser with additional fuctionality like progress bar , bookmarks, back, forward, menu,save, print … is it possible to build it with only java programming or not ? I have the ideas but unable to implement them … Can you help me or suggest me anything?
I covered how to make a basic browser using JEditorPane.
You may like JxBrowser. It allows you to embed a browser.
These are the best. I would like to ask about it but, it seems to literally cover anything I can think of…
Thank you 🙂 Always feel free to ask questions.
Derek? On those java tutorials that you uploaded, does it covered everything about java?
It covers a vast majority of Java. I even make a pretty complex game by the end. You can see the whole thing here Java video tutorial. I don’t know how I did it, but it is the most popular Java video tutorial online as far as I know.
Java Video Tutorials. You wrote in Caption:
“This tutorial starts out slow, but by the end you will be a Java expert!”
I think your tutorial is fast and superb and I hope as you have said to become an expert even before I reached last video.
Thanks a lot for such a nice effort and Please carry on this good work…
Thank you 🙂 I did my best to teach everything about Java. I also have tutorials on object oriented design, algorithms, design patterns, refactoring, UML, etc. to help you become an expert.
Hi Derek I’m just starting out and have no idea what’s going on in video’s,books I just can’t grasp it, so I want to ask, I see you recommend Head first java, is this a good book for someone who has never programmed in their live
Simply the best, turns out it’s like really easy. Your tutorials are by far the best out there, you talented man really talented well done!
Thank you 🙂 I’m glad you find them useful.
Yes the head first books are very good. Have fun 🙂
