Mastering wait(), notify(), and notifyAll() in Java: An Interview Essential

Overview

When to Use wait(), notify(), and notifyAll() methods

we are used in Java for inter-thread communication and synchronization. They are typically used when multiple threads need to coordinate and share resources, but only under specific conditions. Here’s a breakdown of when to use each method:

• Use wait() when a thread needs to wait for a specific condition to be true before it can continue.
• Use notify() when you want to wake up a single waiting thread.
• Use notifyAll() when you want to wake up all waiting threads and allow them to compete for the lock and resume execution.
