java--多线程之后台线程

public class ThreadDaemon {
/**
* @param args
* 后台线程在主进程结束后,也会退出
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
ThreadImplementsTest tlt=new ThreadImplementsTest();
Thread t1=new Thread(tlt);
t1.setName("Daemon Thread test");
t1.setDaemon(true);//如果一个进程中只用后台线程在运行,那么整个进程就会结束。
t1.start();
}
}
Output:

exit

Daemon Thread test====>进入loop()
