import java.util.Random; Two ways to go about using it. Can create a variable: Random rand = new Random(); To use it, do rand.nextInt(num), which will give you a number between 0 and number inside. Or: System.out.println((int)(Math.random() * 10)); Math.random() gives a double number between 0 and 1. Multiply it by a number you wish it random to, then typecast it as int if you want a whole number and no decimal.
