Java多线程之后台线程

将线程设置成后台线程Daemons 主线程结果后，后台线程将自动结果。

 

package wzh.test;

import java.util.concurrent.TimeUnit;

 class SimpleDaemons implements Runnable{

    @Override
    public void run() {
        try {
            while (true) {
                TimeUnit.MILLISECONDS.sleep(100);
                System.out.println(Thread.currentThread().getId()+"  "+this);
            }
        } catch (Exception e) {
            System.out.println("sleep() interrupted");
        }
    }
}

public class SimpleDaemonsMain{
    public static void main(String[] args) throws InterruptedException {
        for (int i = 0; i < 10; i++) {
            Thread daemon=new Thread(new SimpleDaemons());
            daemon.setDaemon(true);
            daemon.start();
        }
        System.out.println(Thread.currentThread().getId()+"All daemons started");
        TimeUnit.MICROSECONDS.sleep(175234231);
    }
    
}
