【并发】百行代码看懂线程状态

package club.interview.concurrent.learn;

import java.util.concurrent.locks.LockSupport;

/**
 * 中断 没有这个线程状态
 * {@link Thread#interrupt()}  标记为中断
 * {@link Thread#isInterrupted()} 不会清除标志位
 * {@link Thread#interrupted()}  静态方法 会清除标志位
 * thread.interrupt(); thread.isInterrupted() Thread.interrupted()
 * 阻塞  block 等锁

结果

1 NEW
2 RUNNABLE
3 TIMED_WAITING
4 WAITING
5 BLOCKED
5.1 isInterrupted = false
5.2 isInterrupted = true
5.3 BLOCKED
get lock
thread is finished
6 TERMINATED
