java random number
import java.util.Random;
Random rand = new Random();
// Obtain a number between [0 - 49].
int n = rand.nextInt(50);
// Add 1 to the result to get a number from the required range
// (i.e., [1 - 50]).
n += 1;

Random number generator in java
// java.util.random example
import java.util.Random;
public class JavaRandomClass
{
public static void main(String[] args)
{
Random random = new Random();
// random integers in range 0 to 999
int randInt1 = random.nextInt(1000);
int randInt2 = random.nextInt(1000);
// printing random integers
System.out.println("Random Integers: " + randInt1);
