线程基础

线程  Thread(类)  runnable(接口，无getName()方法)

线程的创建：              Thread()         Thread(String name)      Thread(Runnable target)     

                                   Thread(Runnabletarget,String name)

线程的方法：

1、线程的启动            void start()

                                   staticvoid sleep(long millis)              

2、线程的休眠            static voidsleep(long millis,int nanos)

3、使其他线程等         void join()     void join(long millis)

待当前线程的终止       void join()

4、当前运行线程释放处理器资源，并重新竞争static void yield()

获取线程的引用：       static Thread currentThread()
