try this
public class ThreadTest implements Runnable {
public static void main(String[] args) {
ThreadTest tt = new ThreadTest();
Thread t1 = new Thread(tt, "First");
t1.setDaemon(true);
Thread t2 = new Thread(tt, "Second");
t2.setDaemon(true);
t1.start();
t2.start();
try {
Thread.sleep(2000);
System.out.println("the first Thread is sleeping for 2 seconds");
} catch (Exception e) {}
synchronized (tt) {
tt.notify();
try {
Thread.sleep(1000);
System.out.println("the second Thread is sleeping for 1 second");
} catch (Exception e) {}
public synchronized void run() {
try {
wait();
} catch (InterruptedException ie) {}
sleepAWhile(4000);
protected synchronized void sleepAWhile(long time) {
try {
Thread.sleep(time);
} catch (Exception e) {}
}
