Write a Java Program to Find Random Number

package com.tutorial4u;

import java.util.Random;

import java.util.Scanner;

public class RandomNumber {

     public static void main(String[] args)

    {

        int maxRange;

        Scanner sc = new Scanner(System.in);

        Random rand = new Random();

       

        System.out.print("Please enter maximum range: ");

        maxRange = sc.nextInt();

       

        for(int i=1; i<=10; i++)

        {

            System.out.println(rand.nextInt(maxRange));

        }

    }

}

Output:

Please enter maximum range: 500

Note : Sometimes situation arises where random numbers are required to be generated between the ranges.

package com.tutorial4u;

import java.util.Random;

import java.util.Scanner;

public class RandomNumber {

     public static void main(String[] args)

    {

           Scanner sc = new Scanner(System.in);

        System.out.print("Please enter Minimum Range : ");

        int minRange = sc.nextInt();

        System.out.print("Please enter Maximum Range : ");

        int maxRange = sc.nextInt();

        Random rand = new Random();

        int value = rand.nextInt(maxRange - minRange) + minRange;

        System.out.println(value);

    }

}

Output :

Please enter Minimum Range : 1000

Please enter Maximum Range : 5000
