简介： 阻塞总数 Blocked count is the total number of times that the thread blocked to enter or reenter a monitor.
阻塞总数
Blocked count is the total number of times that the thread blocked to enter or reenter a monitor. I.e. the number of times a thread has been in the java.lang.Thread.State.BLOCKED state.
等待总数
Waited count is the total number of times that the thread waited for notification. i.e. the number of times that a thread has been in the ava.lang.Thread.State.WAITING or java.lang.Thread.State.TIMED_WAITING state.
当线程试图获取一个内部的对象锁(不是java.util.concurrent库中的锁)，而锁被其它线程占有，则该线程进入阻塞状态。
当线程等待另外一个线程通知调度器的一个条件的时候，它自己进入等待状态。在调用Object.wait()或Thread.join()方法，或者等待java.util.concurrent库中的Lock或Condition时，会出现等待状况
