1.7.4在沉睡中停止

在sleep状态下，停止线程。会进入catch语句，并且清除停止状态值，使其变成false

 6 public class MyThread extends Thread{
 7     @Override
 8     public void run() {
 9         super.run();
10         try {
11             System.out.println("run begin");
12             Thread.sleep(20000);
13             System.out.println("run end");
14         } catch (InterruptedException e) {
15             System.out.println("沉睡中被停只进入catch  "+this.isInterrupted());
16             e.printStackTrace();
17         }
18     }
19 }

前一个实验是先sleep后，在执行interrupt（）

下面实验先停止线程，在进入sleep

 1 package com.cky.thread;
 2 
 3 /**
 4  * Created by edison on 2017/12/3.
 5  */
 6 public class MyThread extends Thread{
 7     @Override
 8     public void run() {
 9         super.run();
10         try {
11             for (int i = 0; i < 100000; i++) {
12                 System.out.println("i="+(i+1));
13             }
14             System.out.println("run begin");
15             Thread.sleep(20000);
16             System.out.println("run end");
17         } catch (InterruptedException e) {
18             System.out.println("先停止再遇到了sleep进入catch  ");
19             e.printStackTrace();
20         }
21     }
22 }

 1 package com.cky.test;
 2 
 3 import com.cky.thread.MyThread;
 4 
 5 /**
 6  * Created by edison on 2017/12/3.
 7  */
 8 public class Test {
 9     public static void main(String[] args) {
10             MyThread th = new MyThread();
11             th.start();
12             th.interrupt();
13 
14 
15 
16     }
17 }

i=99997
i=99998
i=99999
i=100000
run begin
先停止再遇到了sleep进入catch  
java.lang.InterruptedException: sleep interrupted
    at java.lang.Thread.sleep(Native Method)
    at com.cky.thread.MyThread.run(MyThread.java:15)

Process finished with exit code 0

结果分析：

这边由于主线程先执行完了代码，给子线程打了停止标记，当子线程执行时线程停止了，再执行sleep方法，就会进入catch了
