This Instructable will show you the wonders of Java (programming language). You will also be able to DIY (Do It Yourself) at home. There is no cost involved within this Instructable. It's very easy, and requires no other programming language at all.
I have spread the main part over steps 3-5. Simply beacuse there is quite a lot of information.

Step 1: What Is java?
Java is just one of the hundreds of different programming languages in the world. Java language is an object-orientated programming language which was developed by Sun Microsystems. Java programmes are platform independent which means they can be run on any operating system with any type of processor as long as the Java interpreter is available on that system.
Step 2: What You Will Need
You will need the Java Software Development Kit from Sun's Java site. Follow the instructions on Sun's website to install it. Make sure that you add the java bin directory to your PATH environment variable. To find the Java Software Development Kit, go to the top right-hand corner of the screen and you will see a search bar. Type in: Java Software Development Kit. The the search results appear, find the one that says something along the lines of download.http://www.sun.com/java/
Step 3: Writing Your First Java Programme:Part 1
You will need to write your Java programs using a text editor. When you type the examples that follow you must make sure that you use capital and small letters in the right places because Java is case sensitive. The first line you must type is:
public class Hello
This creates a class called Hello. All class names must start with a capital letter. The main part of the program must go between curly brackets after the class declaration. The curly brackets are used to group together everything inside them.
public class Hello
