In this tutorial, I will be teaching you how to create your first Java application.

First - Open notepad
- Once notepad is open you will want to type
public class Hey
This indicates that you are declaring a new class file called Hey

Remember the name, because this is important. You absolutely MUST save your file as Hey.java for it to compile correctly.

- (I'll be using the name "Hey" as my file name, you may use any name.)

Ok, now you should have:
public class Hey
{
}

If you don't have that, copy it into your notepad file, and you'll be ready to move on.
Next, we will want to create our first void.

What is a void?
A void is somewhat of a procedure. Every command inside of the void will be executed when the void is called on.

Ok. Now that you know what a void is, it's time to put it into our coding.
This is what it should look like:
public class Hey
{
public static void main(String args[])
{

}
}

If you don't have that, copy it into your notepad file, and you'll be ready to move on.
Now, we will want to insert our first command, System.out.println("Hey");
This stands for System.outPUT.Print with new line
This means that the System will Ouput Hey into a new line. So let's go ahead and add it in.
You will be finished when you have:
public class Hey
{
public static void main(String args[])
{
System.out.println("Hey this is my first application and I love GzN?");
}
}


Congratulations, you have now completed your first java application!

well actually if you really want to use java download eclipse. it is much more user friendly has some tuts in it and has some good things such as getter and setter generators and auto correctors and completers. so if you are gonna use java i recommend using eclipse.
download for free at : Eclipse Downloads

Actually a void is what the block of code returns. When it's void, it returns nothing after it's finished, if it's int, it returns a number value, etc. This can be useful because if you have a function to for example do a math problem, you would use int because then it would be able to return an integer.

so int and others like that are called Functions
It returns a certain Value once it has been carried out


a void in other languages are called Procedures. Hope that clear up some confusion

something that should be added is that you can't do anything with this until you compile it into a class file then run using cmd or by using the eclipse program
