Java Program: Random Number Generator

Code Example 1:

package org.code2care.example;

import java.util.Random;

public class JavaRandomNumberGeneratorExample {

    public static void main(String[] args) {

        int noOfRandomNumbers = 10;
        generateRandomNumbers(noOfRandomNumbers);

    }

    public static void generateRandomNumbers(int noOfRandomNumbers) {

        Random random = new Random();

        for (int i = 0; i < noOfRandomNumbers; i++) {
            int randomNumber = random.nextInt();
            System.out.println(randomNumber);
        }
    }
}

Output:

-2125433095
836305817
-896405979
-1748201265
1330120858
20769789
1066517992
890512865

Example 2: Generate random numbers between -100 to 100

    public static void generateRandomNumbers(int noOfRandomNumbers) {

        Random random = new Random();

        for (int i = 0; i < noOfRandomNumbers; i++) {
            int randomNumber = random.nextInt(-100,100);
            System.out.println(randomNumber);
        }
    }
