Generate random numbers using Math.random
This java example shows how to generate random numbers using random method of
Java Math class.
*/public class GenerateRandomNumbers {public static void main(String[] args) {

/*
* To generate random numbers, use
* static double random() method of Java Math class.
*
* This method returns a positive double value grater than 0.0
* and less than 1.0
*/

System.out.println(“Random numbers between 0.0 and 1.0 are,”);
for(int i=0; i < 5 ; i++)
System.out.println(“Random Number [“+ (i+1) + “] : ” + Math.random());

/*
* To generate random number between 1 to 100 use following code
*/

System.out.println(“Random numbers between 1 and 100 are,”);
for(int i=0; i < 5 ; i++)
System.out.println(“Random Number [“+ (i+1) + “] : ” + (int)(Math.random()*100));

}
}

/*
Typical output would be
Random numbers between 0.0 and 1.0 are,
Random Number  : 0.7900395454653136
Random Number  : 0.15887365598103076
Random Number  : 0.5570570713930629
Random Number  : 0.017811004461356195
Random Number  : 0.7135560403213513

Random numbers between 1 and 100 are,
Random Number  : 31
Random Number  : 21
Random Number  : 24
Random Number  : 95
Random Number  : 3
