How to run a thread after another?

Question

Create three threads and the main thread. Execute each thread as simultaneous tasks. Display information when exiting each thread.

Answer 1

public class sync extends Thread {

public void run() {

    synchronized (this) {
        for (int i = 5; i > 0; i--) {
            System.out.print("Thread Name :" + Thread.currentThread().getName() + i+"\n");
        }
    }
}

}

class demo {

public static void main(String args[]) {
    sync obj1 =new sync();
    sync obj2 =new sync();
    sync obj3 =new sync();
    obj1.setName("First");
    obj2.setName("Second");
    obj3.setName("Third");
    obj1.start();
    obj2.start();
    obj3.start();
}

}

O/p:

Thread Name :First5 Thread Name :First4 Thread Name :First3 Thread Name :First2 Thread Name :First1 Thread Name :Second5 Thread Name :Second4 Thread Name :Second3 Thread Name :Second2 Thread Name :Second1 Thread Name :Third5 Thread Name :Third4 Thread Name :Third3 Thread Name :Third2 Thread Name :Third1

HOPE THIS HELPS :)
