You can generate Random numbers in Java using the Random class available in java.util package. The following is a code which generates Random numbers between 0 and 100:
import java.util.Random ;public class RandomGenerator { public static void main(String args[]){ int value = 101; Random rm = new Random(); // rm.nextInt() can return Integer.MIN_VALUE (i.e -2147483648) and Math.abs(Integer.MIN_VALUE) returns Integer.MIN_VALUE int randInt = (rm.nextInt() & Integer.MAX_VALUE) % value; System.out.println( " Random Number : " + randInt ); }}You can define seed value using setSeed(long seedValue). There is also get random boolean using nextBoolean() method .
