Thread Sleep Sample Code

Code:
package com.myjava.threads;

import java.util.ArrayList;
import java.util.List;

public class MyThreadSuspend {
    public static void main(String a[]){
        List<ExmpThread> list = new ArrayList<ExmpThread>();
        for(int i=0;i<4;i++){
            ExmpThread et = new ExmpThread(i+10);
            list.add(et);
            et.start();
        }
        for(ExmpThread et:list){
            try {
                et.join();
            } catch (InterruptedException ex) { }
        }
    }
}

class ExmpThread extends Thread{
    private int suspendCount;
    public ExmpThread(int count){
        this.suspendCount = count;
    }
    public void run(){
        for(int i=0;i<50;i++){
            if(i%suspendCount == 0){
                try {
                    System.out.println("Thread Sleep: " + getName());
                    Thread.sleep(500);
                } catch (InterruptedException ex) { }
            }
        }
    }
}
