How can the wait() and notify() methods be called on Objects that are not threads?

Question

How can the wait() and notify() methods be called on Objects that are not Threads? That doesn\'t really make sense, does it?

Surely, it mus

Answer 1

You can stop your thread for time as you want using static Thread class method sleep().

public class Main {
    //some code here

    //Thre thread will sleep for 5sec.
    Thread.sleep(5000);   
}

If you want to stop some objects you need to call this method's within syncronized blocks.

public class Main {

//some code

public void waitObject(Object object) throws InterruptedException {
    synchronized(object) {
        object.wait();
    }
}

public void notifyObject(Object object) throws InterruptedException {
    synchronized(object) {
        object.notify();
    }
}

}

P.S. I'm sory if I wrong understand your question (English is not my native)
