Question

Create two thread classes: ThreadWaiterOne and ThreadWaiterTwo. The thread classes must implement Runnable. In the Run method for ThreadWaiterOne, delay the code for 20 sec and then output to the console "Thread Waiter One is done." The ThreadWaiterTwo class must wait for 5 sec before outputting the console "Thread Waiter Two is done." Finally create ThreadTester that will run the two classes by having them implement Runnable. The thread classes Create two thread classes, Minute.java and Second.java. The Minute.java class will run in a thread and wake up every 60 sec to count the minutes starting with 1 minute. The Second.java class will wake up every second, counting each second starting with 1. Create a tester class StopWatch.java that starts these two classes.

Answer 1

program:1

import java.util.*;
class ThreadWaiterOne extends TimerTask {
public void run() {
System.out.println("Thread Waiter One is done.");
}
}
class ThreadWaiterTwo extends TimerTask {
public void run() {
System.out.println("Thread Waiter Two is done.");
}
}

// Main Class
class ThreadTester
{
public static void main(String[] args)
{
Timer timer = new Timer();
//time in milliseconds
timer.schedule(new ThreadWaiterOne(), 0, 20000);
timer.schedule(new ThreadWaiterTwo(), 0, 5000);
}
}

program:2

import java.util.*;
class ThreadWaiterOne extends TimerTask {
public void run() {
System.out.println("Thread Waiter One is done.");
}
}
class ThreadWaiterTwo extends TimerTask {
public void run() {
System.out.println("Thread Waiter Two is done.");
}
}

// Main Class
class ThreadTester
{
public static void main(String[] args)
{
Timer timer = new Timer();
//time in milliseconds
timer.schedule(new ThreadWaiterOne(), 0, 20000);
timer.schedule(new ThreadWaiterTwo(), 0, 5000);
}
}
