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);

    }
}
