  Java’s Math class has an easy to use random number generator. Math.random(); This method creates a random double value greater than or equal to zero but less than one. Here is an example: public class RandomNumber {   public static void main(String[] args) {     //random number     System.out.println(Math.random());   } } If cast as an int, you can generate many different useful values.     //random number 0 to 9     System.out.println((int)(Math.random()*10));     //random number 1 to 3     System.out.println((int)(Math.random()*3)+1);         //random number -10 to 10     System.out.println((int)(Math.random()*21)-10);          //random number 2 to 10 even numbers only     System.out.println((int)(Math.random()*5)*2+2);
