Write a Java program that implements a multi-thread application that has three threads.

Write a Java program that implements a multi-thread application that has three threads. The first thread generates a random integer for every 1 second; the second thread computes the square of the number and prints; the third thread will print the value of the cube of the number.

Aim: Demonstrate creation of threads using Thread class and Runnable interface, multithreaded programming.

Program:-

import java.util.Random;

class Square extends Thread {
    int x;
    Square(int n) {
        x = n;
    }
    public void run() {
        int sqr = x * x;
        System.out.println("Square of " + x + " = " + sqr);
    }
}


class Cube extends Thread {
    int x;
    Cube(int n) {
        x = n;
    }
    public void run() {
        int cub = x * x * x;
        System.out.println("Cube of " + x + " = " + cub);
    }
}


class Rnumber extends Thread {
    public void run() {
        Random random = new Random();
        for (int i = 0; i < 5; i++) {
            int randomInteger = random.nextInt(10);
            System.out.println("Random Integer generated : " + randomInteger);
            Square s = new Square(randomInteger);
            s.start();
            Cube c = new Cube(randomInteger);
            c.start();
            try {
                Thread.sleep(1000);
            } catch (InterruptedException ex) {
                System.out.println(ex);
            }
        }
    }
}


public class ThreadP {
    public static void main(String[] args) {
        Rnumber n = new Rnumber();
        n.start();
    }
}

Output:-
