🙋 **我** ：线程同步是两个或多个共享关键资源的线程的并发执行。应该同步线程以避免关键的资源使用冲突。操作系统一般有下面三种线程同步的方式：

1. **互斥量(Mutex)**：采用互斥对象机制，只有拥有互斥对象的线程才有访问公共资源的权限。因为互斥对象只有一个，所以可以保证公共资源不会被多个线程同时访问。比如 Java 中的 synchronized 关键词和各种 Lock 都是这种机制。
1. **信号量(Semphares)** ：它允许同一时刻多个线程访问同一资源，但是需要控制同一时刻访问此资源的最大线程数量
1. **信号量(Semaphores)** ：它允许同一时刻多个线程访问同一资源，但是需要控制同一时刻访问此资源的最大线程数量
1. **事件(Event)** :Wait/Notify：通过通知操作的方式来保持多线程同步，还可以方便的实现多线程优先级的比较操
