Thread.sleep(long millis):线程将休眠指定的毫秒数。 Object.wait(long timeout):线程在调用wait()方法时等待指定的时间,如果超时未被唤醒则自动唤醒。 Thread.join(long millis):调用join(long millis)的线程将等待目标线程完成或者超时。 LockSupport.parkNanos(long nanos)和LockSupport.parkUntil(long deadline):...

这四种锁是指锁的状态,专门针对synchronized的。synchronized通过Monitor来实现线程同步,Monitor是依赖于底层的操作系统的Mutex Lock(互斥锁)来实现的线程同步。 无锁 无锁没有对资源进行锁定,所有的线程都能访问并修改同一个资源,但同时只有一个线程能修改成功。

常见的锁包括互斥锁(Mutex)和可重入锁(Reentrant Lock)。 互斥性:互斥性是同步机制的核心概念,指同一时间只有一个线程能够持有某个特定的锁,其他线程需要等待该锁的释放才能获取它。 条件变量(Condition):条件变量用于线程间的通信和协调,使得线程可以按照特定的条件进行等待或唤醒。条件变量通常与锁结合使用,通过等待...
