Here I continue my Sabermetrics Baseball tutorial. If you missed part one, check it out first because in it I show you how to get all of your tools. It is here Sabermetrics.
I’m going to introduce a few new SQL functions being CONCAT, COALESCE and HAVING.
We will also calculate the top players based on RBIs, HRs, Batting Average, On Base Percentage, and Slugging Percentage. And, I’ll show you how to pull in data on the players position and their salary.
In this article I introduce you to the world of Sabermetrics. Sabermetrics is the analysis of baseball statistics to measure player performance, in game probabilities and much more.
With Sabermetrics you’ll be able to do most anything from decide who was the greatest hitter of all time to analyze the probability that your team will win.
But, to get started with Sabermetrics, you need to first get your tools being MySQL and a Baseball Stat Database. Both are free! More info follows the video below.
One of you guys asked me to do a tutorial on Fixing Java Errors. I thought it was a good idea, so here I’ll show you over 30 common Java errors.
Sometimes it is hard to figure out what Cannot be Resolved, Syntax Error on Token, or Method is not Visible mean. But, after watching this video you should better understand.
Also, you’ll learn how to get Eclipse to help you fix Java errors.
In this part of the Java Video Tutorial I show you how to setup Java JDBC in Eclipse.
I then cover how to connect to a MySQL database, query it and get the results of a query. We also look at the Exceptions you’ll need and much more.
I will cover SQL in this tutorial, but not to the extent that I did in the past. My SQL tutorials can be found after the video.
Here I continue covering everything about Java. Today I completely cover reading and writing Java Binary Streams.
I cover everything you need to know including DataOutputStream, FileOutputStream, BufferedOutputStream, all of the reading and writing primitive type methods and more.
All of the code follows the video. It is heavily commented.
In this part of my Java Video Tutorial, I completely cover how to both write to and read character streams from files.
I explain all of the following: PrintWriter, BufferedWriter, FileWriter, BufferedReader, FileReader, common file exceptions and much more.
All of the code follows the video. It is heavily commented and will help you build your Java code repository while helping you to learn Java better.
In this part of the Java Video Tutorial, I completely cover the Java File Class.
I’ll show you how to create and delete files and directories. How to pull lists of files from directories and manipulate them. We’ll look at the errors to watch out for and a whole bunch more.
All of the code follows the video and should be used to help you understand this topic better.
You asked for a giant tutorial that covers every Swing component, and in this tutorial I deliver. This is a big Java Swing Tutorial!
Here I create a complicated Java Swing layout. I set up everything in a GridBagLayout, but add a Box and FlowLayout to it. I then show you how to use all of these components: JLabel, JTextField, JComboBox, JSpinner, JSlider, JRadioButton, ButtonGroup, JCheckBox, JTextArea, JScrollPane, ChangeListener, pack and more.
All of the code follows the video.
In this part of the Java Video Tutorial series, I cover GridLayout, GridBagLayout, GridBagConstraints, Font, Insets and much more.
I do this by showing you how to create a calculator layout with Java Swing. You’ll see just how easy it is to layout a nice GUI interface using constraints. You don’t necessarily need to measure X and Y coordinates to get everything to look right.
The code follows the video and it is heavily commented.
In this part of my Java Video Tutorial, I cover 3 different Swing layout managers. I revisit the the layout manager we have been using by default being Flow Layout. As well I introduce the Border and Box layout managers.
I answer many common questions like how do you get to components in a Border frame quadrant? How do I add space between components and much more.
The code follows the video and will help you better learn.
In this part of the Java Video Tutorial, I introduce the last Swing component called the JTree. I won’t just be introducing the JTree however. I will also be reviewing much of what you have learned.
It is my belief that if you see tools being used in many different ways, that you will just remember them. I will review dimensions, frames, panels, buttons, scroll bars, listeners and so much more.
Use the code after the video to better learn how to use Java Swing.

In this part of the Java Video Tutorial, I focus on the Java Swing JSpinner component. I’ll show you how to cycle through numbers, dates and just about anything else. I also revisit the Dimension, Date and Calendar libraries.
Most Java Tutorials gloss over topics like this, but I decided I wanted to create a truly comprehensive tutorial.
Just like always it is best to follow the tutorial with the code. It follows the video.
Here I continue making the most comprehensive Java Video Tutorial ever. Today I’ll cover how to create list boxes using Java Swing.
More specifically I’ll cover JLists, DefaultListModel, using JScrollpane with JList and a whole bunch more.
Like always, the heavily commented code follows the video. Leave any questions below.
In this video tutorial, I show you how to create combo boxes in Java Swing. This tutorial is also a review of everything I’ve previously gone over.
I review how to create the frame and panel. How to add buttons with event listeners. I also review JOptionPane. I’m slowing down a bit so that I’m sure you understand everything that proceeded this tutorial.
All of the code follows the video below. Leave any questions below.
Today I complete the Java Swing tutorial I started in part 22 of the Java tutorial.
I implement the Swing event listeners. I then cover how to format numbers in Java so that they have commas or are displayed as currency. JOptionPane, a useful popup window in Java is introduced. And, finally I review much of what we have done in past Java Swing Tutorials.
All of the code follows the video. You should look at it to help you learn.
In this part of the Java Video Tutorial, I continue building your knowledge on how to use Java Swing. I actually broke this tutorial into 2 pieces. It will continue in part 23 of this series.
I cover a new GUI listener called the ChangeListener. I also introduce check boxes, radio buttons, groups, borders and sliders.
The code for both tutorials follows the video below.
In this part of my Java Video Tutorial, I will cover GUI Event Handling. If you missed my Java Swing video tutorial, watch that first.
Here I show you how to implement the ActionListener, KeyListener, MouseListener and WindowListener. I also show you some easy ways to use interfaces so that you don’t have to memorize all of the required methods for each interface.
All of the code follows the video. Definitely look at it so that you will find it easier to learn.
I introduce you to Graphical User Interfaces (GUI) in this part of my Java Video Tutorial. I focus specifically on Java Swing and its components.
We figure out how to display frames, panels, labels, buttons, text areas and more. I also go over the Dimension object and the Java Toolkit, which allows you to ask questions of the operating system.
All of the code follows the video and it’s set up to help you retain this information.

Every day I see scam after scam about how you can get rich online. Today I’m going to show you how to create an online store for next to nothing! I don’t even want your email, or anything 🙂
You will however have to do a little work to get this free money making site. If you’re willing to invest the time, you will either be able to make stores for others, or yourself.
The payoff is a store that will make money in its first month.
In this part of my Java Video Tutorial, I cover Java Regular Expressions. You use regular expressions when you want to search for data. You then use codes to define what that data looks like.
So, if you are looking for a 5 digit number, you could type \\d{5} and Java does the rest!
The code that follows the video will help you see how easy regular expressions are.
