此时主线程会BLOCK住等待lock被释放，此时jstack的输出可以看到main线程状态是BLOCKED。这里要注意的是只有synchronized这种方式的锁（monitor锁）才会让线程出现BLOCKED状态，等待ReentrantLock则不会。3) 让线程处于TIMED_WAITING状态 public static void timedWaiting() { final Object lock = new Object()...
* is waiting for a specified thread to terminate. */ WAITING, 从中能够清晰的得到线程处于BLOCKED和WAITING状态的场景。 BLOCKED状态 线程处于BLOCKED状态的场景。 当前线程在等待一个monitor lock,比方等待运行synchronized代码块或者使用synchronized标记的方法。
java线程中含有waiting与blocked两种状态,两种状态有着明显的区别,本文从jdk源码中两种状态的设计角度和状态进入角度来分析两者的区别。 源码分析 /* * Thread state for a thread blocked waiting for a monitor lock. * A thread in the blocked state is waiting for a monitor lock * to enter a synchronized...

1,线程状态为“waiting for monitor entry”: 意味着它在等待进入一个临界区,所以它在”Entry Set“队列中等待。 此时线程状态一般都是 Blocked: java.lang.Thread.State:BLOCKED(on object monitor) 2,线程状态为“waiting on condition”: 说明它在等待另一个条件的发生,来把自己唤醒,或者干脆它是调用了 sleep...
