java.util.Random handles random numbers in Java:

Expand|Select|Wrap|Line Numbers
  1. Random rand = new Random()
  2. int aRandomInt = rand.nextInt(10) // Random int 0 (inclusive) to 10 (exclusive)
Check out the API for more info.

For a fast random you can use
Expand|Select|Wrap|Line Numbers
  1. Math.random()
returns a double between 0 and 1. To get an int say between 0 and 100

do
Expand|Select|Wrap|Line Numbers
  1. (int)Math.random()*100;
