What is the wait and notify mechanism in Java?

Can you explain the wait and notify mechanism in Java?

Sure! In Java, wait and notify are methods used for inter-thread communication. They allow threads to pause execution and wait for a condition to be met.

How do I use wait and notify in my code?

You can use wait() inside a synchronized block to make a thread wait, and notify() to wake up a waiting thread. Make sure to handle InterruptedException.

Can you give me a code example?

Certainly! Here's a simple example:

synchronized (sharedObject) {
    while (!condition) {
        sharedObject.wait();
    }
    // Perform action when condition is true
}

// In another thread
synchronized (sharedObject) {
    // Change condition
    sharedObject.notify();
}

What happens if I forget to synchronize?

If you forget to synchronize, you may encounter inconsistent states or unexpected behavior, as multiple threads could access shared resources simultaneously.
