NEW RUNNABLE TERMINATED代码演示

用如下的代码, 演示打印出线程的NEW RUNNABLE TERMINATED 三种状态.
先创建出线程的时候, 调用getState()方法进行打印, 此时应该是打印出NEW .
接着调用了start方法, 此时为RUNNABLE .
接着主线程休眠10ms, 让子线程进入运行中的状态, 此时打印线程状态应该也为RUNNABLE .
最后, 主线程休眠1s, 让子线程执行1s, 此时子线程的run方法的循环,执行完毕, 再次调用线程状态的方法, 应该打印出 TERMINATED

public class ThreadNewRunnableTerminatedState implements Runnable { 
    public static void main(String[] args) { 
        Thread thread = new Thread(new ThreadNewRunnableTerminatedState());
        //NEW 
        System.out.println( thread.getState());
        thread.start();
         //RUNNABLE 
        System.out.println( thread.getState());
        try { 
            Thread.sleep(10);
        } catch (InterruptedException e) { 
            e.printStackTrace();
        }
         //RUNNABLE 
        System.out.println( thread.getState());
        try { 
            Thread.sleep(1000);
        } catch (InterruptedException e) { 
            e.printStackTrace();
        }
         //TERMINATED
        System.out.println( thread.getState());
    }
    @Override
    public void run() { 
        for (int i = 0; i < 10000; i++) { 
            System.out.println(i);
        }
    }
}

控制台的打印, 分别为如下的三张图, 如上面分析的一样 . 一开始打印的是 new runnable

运行中也是打印runnable

线程执行完毕, 打印 TERMINATED
