The wait() method causes the current thread to wait until another thread invokes the notify() or notifyAll() methods for that object. The notify() method wakes up a single thread that is waiting on that object's monitor. The notifyAll() method wakes up all threads that are waiting on that object's monitor.Jul 2, 2563 BE

public class WaitNotifyTest {
   private static final long SLEEP_INTERVAL = 3000;
   private boolean running = true;
   private Thread thread;
   public void start() {
      print("Inside start() method");
      thread = new Thread(new Runnable() {
         @Override
         public void run() {
            print("Inside run() method");
            try {
               Thread.sleep(SLEEP_INTERVAL);
            } catch(InterruptedException e) {
               Thread.currentThread().interrupt();
            }
            synchronized(WaitNotifyTest.this) {
               running = false;
               WaitNotifyTest.this.notify();
            }
         }
      });
      thread.start();

            wait(); //waiting, not running
         }
