If you want to read input, try:
Code:
java.util.Scanner inputReader = new java.util.Scanner(System.in);

int number;
System.out.print("Prompt:> ");
number = inputReader.nextInt();
There's other ways to do this, but this is the easiest, and the cleanest in my opinion.

It's all good. One thing I would suggest doing if you're going to get serious into Java programming, is to pick up Java In A Nutshell. It covers all of the basic classes (no GUI classes - java.awt.* & javax.swing.*).

Sidenote: I just noticed the price of Java In A Nutshell - used & new copies for less than $20 USD!!! When I got that book last year, I paid about $70 CAD after tax!
