How has ReadWriteLock changed in recent Java versions?

import java.util.concurrent.locks.ReentrantReadWriteLock;

public class ReadWriteLockExample {
    private final ReentrantReadWriteLock rwLock = new ReentrantReadWriteLock();
    private String data = "Initial Data";

    public String readData() {
        rwLock.readLock().lock();
        try {
            return data;
        } finally {
            rwLock.readLock().unlock();
        }
    }

    public void writeData(String newData) {
        rwLock.writeLock().lock();
        try {
            this.data = newData;
        } finally {
            rwLock.writeLock().unlock();
        }
    }

    public static void main(String[] args) {
        ReadWriteLockExample example = new ReadWriteLockExample();

        // Simulating multiple readers and a writer
        Thread reader1 = new Thread(() -> System.out.println(example.readData()));
        Thread reader2 = new Thread(() -> System.out.println(example.readData()));
        Thread writer = new Thread(() -> example.writeData("Updated Data"));

        reader1.start();
        reader2.start();
        writer.start();
    }
}
