java.lang.Thread.State枚举类中定义了六种线程的状态,可以调用线程Thread中的getState()方法获取当前线程的状态。 代码语言:javascript 复制 publicenumState{NEW,RUNNABLE,BLOCKED,WAITING,TIMED_WAITING,TERMINATED;} 具体状态切换如下图所示,下图源自《Java并发编程艺术》 📌由图4-1中可以看到,线程创建之后,调用star...
thread2随后尝试获取同一个锁,但由于锁已被thread1持有,因此thread2会进入BLOCKED状态,直到thread1释放锁。通过运行此代码并观察线程状态,可以更好地理解BLOCKED状态的行为。

在这段代码中,我们通过 getState 方法获取线程的状态,并根据状态判断线程是否被阻塞。 4. 总结 本文介绍了如何实现 “java thread blocked”。通过创建线程、定义线程的运行逻辑、设置阻塞条件、唤醒被阻塞的线程以及检查阻塞状态,我们可以实现线程的阻塞和唤醒。
