Java program to generate random numbers

In this article we will learn to implement a Java program to generate random numbers. A Java program is provided below to generate a set of random numbers between two numbers x1 and x2, and x1>0.

Program is as follows:

import java.util.*;
class RandomGen
{
	public static void main(String args[])
	{
		int min = 2;
		int max = 10;
		Random rand = new Random();
		for(int i=1;i<=5;i++)
		{
			int num = rand.nextInt(max-min+1)+min;
			System.out.println("Random number between "+min+" and "+max+" is: "+num);
		}
	}
}

Output for the above program is as follows:

Random number between 2 and 10 is: 10
Random number between 2 and 10 is: 8
Random number between 2 and 10 is: 9
Random number between 2 and 10 is: 4
Random number between 2 and 10 is: 7
