ReentrantLock vs synchronized

• Lock显示锁； synchronized隐式锁
• lock只能锁代码块；synchronized可以锁代码块+方法锁
• Lock锁性能>synchronized

public class ReentrantLockTest {
    public static void main(String[] args) {
        Lock lock = new ReentrantLock();
        try {
            lock.lock();
        } finally {
            lock.unlock();
        }
    }
}
