第一种：

线程类

public class MyThread extends Thread {

@Override

public void run() {

try {

System.out.println("在沉睡中被停止，进入try！"+this.isInterrupted());

System.out.println("run begin");

Thread.sleep(200000);

System.out.println("run end");

} catch (Exception e) {

System.out.println("在沉睡中被停止，进入catch！"+this.isInterrupted());

e.printStackTrace();

}

}

}

测试类

public class Test {

public static void main(String[] args) {

try {

MyThread mt = new MyThread();

mt.start();

Thread.sleep(100);

mt.interrupt();

} catch (Exception e) {

System.out.println("main catch");

e.printStackTrace();

}

System.out.println("end!!!");

}

}

console结果：

在沉睡中被停止，进入try！false

run begin

end!!!

在沉睡中被停止，进入catch！false

java.lang.InterruptedException: sleep interrupted

at java.lang.Thread.sleep(Native Method)

at com.qf.MyThread.run(MyThread.java:14)

===============================================================

第二种：线程类不变，测试类注释sleep方法

public class Test {

public static void main(String[] args) {

try {

MyThread mt = new MyThread();

mt.start();

//Thread.sleep(100);

mt.interrupt();

} catch (Exception e) {

System.out.println("main catch");

e.printStackTrace();

}

System.out.println("end!!!");

}

}

console结果：

java.lang.InterruptedException: sleep interrupted

at java.lang.Thread.sleep(Native Method)

at com.qf.MyThread.run(MyThread.java:14)

end!!!

在沉睡中被停止，进入try！true

run begin

在沉睡中被停止，进入catch！false

想问下：

为什么两次结果“在沉睡中被停止，进入try！false”和“在沉睡中被停止，进入try！true”会不一样？
