// Aim: a) Write a program to simulate a buzzer. The program should make use of the Thread class.

// Create a class named Buzzer that extends the Thread class. Create an interface named

// MonitorTime which contains a method setBuzzerTime() . Your Buzzer class should

// implement this interface. Override setBuzzerTime() method to set the buzzer time delay in

// milliseconds and the number of times the buzzer should be repeated. Also, include

// methodsblowBuzzer to start the buzzer.

package com.College_Java_Lab.Exp_9_Threads.Record;

// Source code:

import java.util.Scanner;

interface MonitorTime{

void setBuzzerTime(int time);

}

public class Buzzer extends Thread implements MonitorTime {

@Override

public void setBuzzerTime(int time) {

try {

Thread.sleep(time* 1000L);

}

catch (InterruptedException e) {

System.out.println(e.getMessage());

}

Buzzer( int no ) {

System.out.println( no + " Buzzer started...");

this.start();

}

static void methodsblowBuzzer (int n, int time ){

for( int i = 1; i <= n; ++i ) {

Buzzer buzz = new Buzzer( i );

buzz.setBuzzerTime(time);

}

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.print("Enter number of times buzzer should be repeated : ");

int n = in.nextInt();

System.out.print("Set Buzzer time delay in seconds : ");

int time = in.nextInt();

methodsblowBuzzer( n, time);

}

// INPUT/OUTPUT:

// Enter number of times buzzer should be repeated : 3

// Set Buzzer time delay in seconds : 1

// 1 Buzzer started...

// 2 Buzzer started...

// 3 Buzzer started...
