线程的创建

　MyThread my = new MyThread();
　　my.start();

 1  //当前线程可转让cpu控制权，让别的就绪状态线程运行（切换）
 2  public static Thread.yield() 
 3  //暂停一段时间
 4  public static Thread.sleep()  
 5  //在一个线程中调用other.join(),将等待other执行完后才继续本线程。　　　　
 6  public join()
 7  //中断线程->
 8 //终端只会影响到wait状态、sleep状态和join状态。被打断的线程会抛出InterruptedException。
 9 //正常线程不会去检测  不受影响
10  public interrupte()

 7     public static void main(String[] args) {
 8         //创建 callable
 9         MyCallable myCallable = new MyCallable();
10         //可以接收 callable  的返回值   判断线程终止
11         FutureTask<Integer> future = new FutureTask(myCallable);
12         //开启线程
13         new Thread(future).start();
