Mis on wait operaatori roll ja milleks seda kasutatakse programmeerimises või süsteemides?

The wait() operation in Java programming is used to organize interaction between threads. It causes the current thread to suspend execution and release the monitor of the object on which wait() was called, until another thread calls notify() or notifyAll() on the same object.

This is important for correct synchronization and waiting for certain conditions without active polling (busy waiting).

Example of usage:

synchronized (sharedObject) {
    while (!condition) {
        sharedObject.wait(); // thread waits until condition becomes true
    }
    // execution after waking up
}

Thus, wait() helps manage threads efficiently, allowing one thread to wait for an event that will occur in another.
