1、start() ,启动一个线程是如何实现的? 2、java线程状态机的变化过程以及如何实现的? 3、 1、start方法的源码如下: new Thread(Runnable);代码内部实际代码如下: View Code 然后看start方法代码如下: /*** Causes this thread to begin execution; the Java Virtual Machine * calls the run method of this...

在oracle官方文档 Java Thread Primitive Deprecation提及强制结束线程会导致线程竞争得到的锁所保护的对象会处于不一致状态,即失去可见性,所以stop()方法被废弃。 所以jdk6后就把线程终止的权利交由线程自身实现,即为中断。线程对于是否终止自己具有决定权,线程自己怎么实现终止被称为中断策略。而Java语言提供了...
