Building on @shilpa.chandel’s point, if your use case is straightforward and you want a simpler java mutex approach, you can rely on Java’s built-in synchronized keyword. It automatically handles locking without requiring explicit lock() and unlock() calls.*

public class SynchronizedMutexExample {
    public synchronized void criticalSection() {
        System.out.println("Thread " + Thread.currentThread().getName() + " is in the critical section.");
        // Critical section logic here
    }
}

:white_check_mark: Why use this?

  • Simple and easy to use.
  • No explicit lock management needed.
  • Built directly into Java.

:rotating_light: Downside:

  • Less flexible than ReentrantLock.
  • No tryLock() or lockInterruptibly() support.
