/\*  
\* 如何使用接口来定义线程？？？  
\* 1.实现Runnable类  
\* 2.创建Runnable类对象  
\* 3.把Runnable类对象传递给thread(Runnable)构造一个thread的对象  
\* 4.调用thread的对象的start()，来启动线程。

// Multiple markers at this line  
// \- The static method sleep(long) from the type Thread should be accessed in a  
// static way  
thr1.start();  
  
  
// 这句：Time1 th=new Time1();报错：Multiple markers at this line  
// \- No enclosing instance of type Time is accessible. Must qualify the allocation with an enclosing instance of type Time (e.g. x.new A() where x is an instance of  
// Time).  
// \- The local variable th is never read
