This is also a very important part of the course. First lets create a simple variable to work with. Under the part of code that says: public static void main(String[] args) { you need to create a variable. Creating a variable in Java is very easy. First you need to type the type of variable so here let's use an int then you type the name of the variable (This can be anything you want to call it) then you simply add an = and a number of what you want the value to be so here let's say 50: int MyVar1 = 50; Then we always finish with a semi colon ; to say that you are done with that line of code. Now within minutes you have created a variable that you can use to do many things with.
