Daemon线程:一个在背景执行服务的线程

public class SimpleThread{public static void main(String[] args){System.out.println("主线程开始");Thread thread = new Thread(new Runnable(){public void run(){while(true){System.out.println("t");}}});thread.start();System.out.println("主线程结束");}}

 

 

java SimpleThread,then,Ctrl+C:

 

解决：

1、ctrl+c;

2、System.exit();

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

 

Daemon线程：

1、如果所有的费Daemon线程结束了，这Daemon线程自动终止！

2、Daemon线程产生的线程也是Daemon线程；

3、setDaemon();isDaemon();

 

public class SimpleThread{public static void main(String[] args){System.out.println("主线程开始");Thread thread = new Thread(new Runnable(){public void run(){while(true){System.out.println("t");}}});thread.setDaemon(true);thread.start();System.out.println("主线程结束");}}
