Write a Java program that implements a multithreaded application that has three threads.

First thread generates a random integer for every 1 second;

second thread computes the square of the number and prints;

third thread will print the value the cube of the number.

package Multithread_Application;

import java.util.Random;

import java.util.concurrent.ExecutorService;

import java.util.concurrent.Executors;

import java.util.concurrent.TimeUnit;

class Square implements Runnable {

private int num;

Square(int n) {

num = n;

}

public void printSquare() {

System.out.println("Square of " + num + " is " + (num * num));

}

public void run() {

printSquare();

}

class Cube implements Runnable {

private int num;

Cube(int n) {

num = n;

}

public void printCube() {

System.out.println("Cube of " + num + " is " + (num * num * num));

}

public void run() {

printCube();

}

class RandInt extends Thread {

private final ExecutorService executor = Executors.newFixedThreadPool(2);

public void printRandom() throws InterruptedException {

Random rd = new Random();

while (true) {

int rnum = rd.nextInt(10);

System.out.println("Random Number is " + rnum);

Thread.sleep(3000);

executor.submit(new Square(rnum));

executor.submit(new Cube(rnum));

}

public void run() {

try {

printRandom();

} catch (InterruptedException e) {

}

public void shutdown() {

executor.shutdown();

}

public void awaitTermination() throws InterruptedException {

executor.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);

}

public class multithread {

public static void main(String[] args) {

RandInt ob1 = new RandInt();

ob1.start();

try {

Thread.sleep(15000); // Run for 15 seconds

ob1.shutdown();

ob1.awaitTermination();

} catch (InterruptedException e) {

e.printStackTrace();

}
