Using “notify()” & “wait()” instead of “suspend()” and “resume()” to control a thread

Question

I\'m trying to learn how to pause and resume a thread in java. I\'m using an Applet that implements Runnablehas 2 buttons \"Start\" and \"Stop\".

Answer 1

I think you have to synchronize on the thread in order to call wait and notify. Try to use

synchronized (th) {
    th.notify();
}

and the same with wait().
