What are some examples of ReentrantLock in Java?

Can you explain what ReentrantLock is in Java?

ReentrantLock is a synchronization aid that allows threads to lock and unlock resources in a flexible way.

What are some practical examples of using ReentrantLock?

One example is managing access to a shared resource, like a bank account, where multiple threads may try to update the balance.

How does ReentrantLock differ from synchronized blocks?

ReentrantLock offers more features, such as tryLock, timed lock, and the ability to interrupt threads waiting for a lock.

Can you show me a code snippet using ReentrantLock?

Sure! Here's a simple example:

import java.util.concurrent.locks.ReentrantLock;

public class Counter {
    private int count = 0;
    private final ReentrantLock lock = new ReentrantLock();

    public void increment() {
        lock.lock();
        try {
            count++;
        } finally {
            lock.unlock();
        }
    }
}
