如何使用JUnit测试读写锁？

import org.junit.Test;
import java.util.concurrent.locks.ReadWriteLock;
import java.util.concurrent.locks.ReentrantReadWriteLock;

public class ReadWriteLockTest {

    @Test
    public void testReadWriteLock() {
        // 初始化读写锁
        ReadWriteLock lock = new ReentrantReadWriteLock();

        // 读操作
        lock.readLock().lock();
        try {
            // 执行读操作
            // ...
        } finally {
            lock.readLock().unlock();
        }

        // 写操作
        lock.writeLock().lock();
        try {
            // 执行写操作
            // ...
        } finally {
            lock.writeLock().unlock();
        }
    }
}
