Selgitage, mida tähendab meetod notify lõimedevahelise suhtluse kontekstis ja kuidas seda kasutatakse

In the context of thread interaction in Java, the notify method is used to wake up one of the threads that are in a waiting (wait) state on a monitor object.

When a thread calls wait() on an object, it releases the monitor and enters a waiting state. Another thread, after changing the state, can call notify() on the same object to wake up one of the waiting threads. If you want to wake up all waiting threads, notifyAll() is used.

Example usage:

synchronized (sharedObject) {
    // change the state of sharedObject
    sharedObject.notify(); // wake up a waiting thread
}

It is important that notify is called inside a synchronized block to ensure ownership of the object's monitor.

This way, notify helps coordinate thread work, allowing one thread to signal others that the state has changed and they can continue working.
