In this Java Video Tutorial, I continue to teach you about Java Threads. If you missed the last part, watch it first here last Java Tutorial.
Today I cover how to lock down methods, synchronized, thread pools, scheduleAtFixedRate and numerous other Java Thread methods.
Use the code that follows the video to make it easier to follow this tutorial. It is heavily commented and will help you.
In this Java Video Tutorial I cover how to use Java threads.
A thread is just a block of code that is expected to execute while other blocks of code execute. That’s it. When you want to execute more than one block of code at a time you have to alert Java.
In this video I show you how to alert the interpreter. Part 1 of this series is here Java Video Tutorial. Heavily commented code follows the video.
In this part of my Java Video Tutorial, I continue to provide you with a complete understanding of Java.
Today I’m covering the Object and Class class, along with clone. We will explore all of the methods that every object gets by default.
Use the code that follows the video to help you learn. If you missed the previous parts make sure you check them out here Java Video Tutorial.
Ever since I started my Java Video Tutorial, I’ve received numerous requests from you to create a Minecraft Modding Guide. In this tutorial, I’ll show you how to setup everything you need to start making mods for Minecraft.
The steps are specific to the Mac platform, but everything is very similar for PCs. Actually it is easier to do this on a PC. The PC directions follow the video.
I thought this tutorial would nicely accompany my Java tutorial. I guess we’ll see
In this part of the Java Video Tutorial I cover interfaces, abstract classes, abstract methods and more.
You need interfaces and abstract classes because Java doesn’t allow you to inherit from more than one other class. You would use an interface when you want to force the user of the interface to create every method in the interface.
You use an abstract method when you need some flexibility. You’ll learn more in the video below.
In this Java video tutorial I cover Polymorphism, Inheritance, Protected, Final, Instanceof and a bunch more.
These topics are not complicated, but for some reason they are normally presented in complicated ways.
Use the code that follows the video to help you gain a complete understanding of these topics. If anything isn’t 100% clear leave a comment below and I’ll help.
In this part of the Java Video Tutorial I cover most every method available for manipulating Strings and StringBuilders.
This is one of the last simple Java Tutorial videos. Everything after this will cover advanced topics.
All of the code follows the video. It is very heavily commented. If you print it out it will help you better retain this information.
I’ve received a bunch of emails from people having WordPress HTTPS problems. In this tutorial, I’ll show you how to setup a WordPress HTTPS site, fix Google HTTPS errors, get the cheapest SSL certificate and more.
It sounds like allot of work, but it is actually very easy to make your site HTTPS compliant.
If you’re getting the Google Chrome Error : Google Chrome has detected either high-risk insecure content on the page or problems with the site’s certificate I’ll fix that too!
In this part of the Java Video Tutorial I cover Java Linked Lists.
The LinkedList class is a collection based on a linked list instead of an array like the ArrayList. They are good when you plan to add and delete items. They aren’t particularly efficient at providing access based off of index searches though.
Nearly every Java Linked List method is shown below. Make sure you look for the code that follows the video, so you completely understand Linked Lists.
In this part of my Java Video Tutorial I introduce Java collection classes. Specifically I cover how to use Java ArrayLists.
Java ArrayLists make it easy to keep track of groups of objects. A Java ArrayList differs from a java array in that it automatically resizes itself when you add or remove values.
I’ll go over nearly every Java ArrayList method in the video below. The code follows the video and it is heavily commented to help you learn easily.
In this tutorial I do something kind of crazy. I try to teach programming logic by writing code right out of my head. You probably won’t understand everything in this video, but that’s OK.
I continue making a simple game in Java. I specifically make a method that allows my monsters to move on the game board without landing on each other and blocks them from falling off the board.
If you missed part 1 definitely check out Java Video Tutorial pt 1.
After my last video I received a bunch of messages asking me to cover Java Arrays. So in this video I go over everything you’d ever want to know about Java Arrays.
I show you how to create arrays, numerous ways to populate them, tricks involving multidimensional arrays, the enhanced for loop, Array library methods and more.
If you missed part 1 of this series check it out first here Java Video Tutorial.
Like always heavily commented code follows the video.
I thought it would be fun to teach Java while I make a video game. This is a simple game, but it will teach a lot of the logic needed to make your own game.
This tutorial will teach you about arrays, class fields, class methods, how to set a default value for an array, and a ton of logic.
I hope you like it. If you missed the previous parts though you should check them out first here Java Video Tutorial.
Recently I received a bunch of emails asking how to install java libraries. So, in this tutorial I’ll show you how.
Since I use Eclipse in all of my tutorials, I’ll show you how to install java libraries with Eclipse. I use Eclipse because it is free and looks the same on every operating system.
Specifically I’ll show you how to install the very popular Apache Commons Java Library.
In this part of my Java Video Tutorial I show you how to create classes in Java.
I cover Java fields (class variables) and methods (functions) first. I then explain what a private field is in detail. We then move on to what it means to overload a method, what a constructor is and how to overload a constructor.
Don’t worry. It sounds much more complicated than it is. You should however check out the previous tutorials before you try to learn this stuff here Java Video Tutorial.
In this part of my Java Video Tutorial I cover Java Exception handling. An exception is an object created when an error occurs.
I explain in this video the difference between run time and checked exceptions. I show you how to use try, catch and finally. We review the most common errors you will come across. I show you how to catch all and ignore individual exceptions. Yes, everything Java Exception wise will be covered.
If you missed part 1 watch it first here Java Video Tutorial.
In this tutorial, I’ll show you how to increase internet sales for the shopping cart that I created for you. The shopping cart was free and I’ll show you how to increase internet sales now for free with the Google Merchant program!
If you haven’t seen my shopping cart tutorial, check that out so you know how to use that free cart theme here WordPress Shopping Cart Tutorial.
It’s amazing that such great tools are available, and I’m so happy to provide them to you 🙂
Here I continue my Java Video Tutorial by covering methods, or functions in Java.
I spend a considerable amount of time on those things that tend to confuse people who are learning Java. I review how class variables differ from local variables and provide numerous examples of methods.
If you missed the first tutorial see Java Video Tutorial, since I use a lot of code here that I explained previously. To help you better understand this video, see the code below.
In part 4 of my Java Video Tutorial I cover looping in Java. This tutorial uses a lot of what I previously taught in the first Java Video Tutorial, so watch the previous parts first.
Here I start out explaining while loops. I provide numerous examples including how to calculate PI with a while loop.
I then go on to explain how do while loops work. I finish the tutorial by covering the for loop.
In this tutorial I show you the if statement, relational operators, logical operators, ternary operator and the switch statement.
If you haven’t watched part 1 watch it first here Java Video Tutorial.
As you watch this video, you will be able to follow it easier if you have the commented code in front of you. It follows the video below.
While this tutorial has been slow it will get much more complicated quickly. So, make sure you understand everything I cover in the beginning.
