多线程详解p15、守护线程

package Thread;
public class TestDaemon {
    public static void main(String[] args) {
        YYou yYou = new YYou();
        God god = new God();
        Thread thread = new Thread(god);
        thread.setDaemon(true);//默认是false为用户线程
        thread.start();
        new Thread(yYou).start();
    }
}
class  YYou implements Runnable {
    @Override
    public void run() {
        for (int i = 0; i < 100; i++) {
            System.out.println("还活着");
        }
        System.out.println("End World");
    }
}class God implements Runnable{
    @Override
    public void run() {
        while (true) {
            System.out.println("God守护着你");
        }
    }
}
