Question

Here is a runnable task, called TaskThread. This task performs some work and then periodically reports what percent of the work it has completed:

import java.util.*;
public class TaskThread implements Runnable {
private int taskNumber;

TaskThread(int number) {
taskNumber = number;
}
public void run() {
for (int i=0;i<=100;i+=20) {
// Perform some task ...
System.out.println("Task number: " + taskNumber
+ ", percent complete: " + i );
try {
Thread.sleep((int)(Math.random() * 1000));
}
catch (InterruptedException e)
{
}
}//end for
}//end main
}//end class

You're allow to have two threads. Write a main method to produce the following ouput:

Task number: 1, percent complete: 0
Task number: 0, percent complete: 0
Task number: 1, percent complete: 20
Task number: 0, percent complete: 20
Task number: 1, percent complete: 40
Task number: 1, percent complete: 60
Task number: 0, percent complete: 40
Task number: 0, percent complete: 60
Task number: 1, percent complete: 80
Task number: 1, percent complete: 100
Task number: 0, percent complete: 80
Task number: 2, percent complete: 0
Task number: 2, percent complete: 20
Task number: 0, percent complete: 100
Task number: 2, percent complete: 40
Task number: 3, percent complete: 0
Task number: 3, percent complete: 20
Task number: 3, percent complete: 40
Task number: 2, percent complete: 60
Task number: 3, percent complete: 60
Task number: 3, percent complete: 80
Task number: 2, percent complete: 80
Task number: 2, percent complete: 100
Task number: 3, percent complete: 100

I still dont know how to implement main method with output task 2 and 3 within only using 2 thread.

Hint: using Thread pool.
