### 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  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMzMjI5NjY5_size_16_color_FFFFFF_t_70_pic_center][]  
运行中也是打印runnable  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMzMjI5NjY5_size_16_color_FFFFFF_t_70_pic_center 1][]  
线程执行完毕, 打印 TERMINATED
