Java多线程（六）守护进程

守护进程：当进程中不存在非守护线程了，则守护线程自动销毁；

public class DaemonThread extends Thread{

    private int i =0;

    public void run(){

        try {

            while(true){

                i++;

                System.out.println("i="+i);

                Thread.sleep(1000);

            }

        } catch (InterruptedException e) {

            // TODO Auto-generated catch block

            System.out.println("test");

            e.printStackTrace();

        }

    }

    public static void main(String[] args) throws InterruptedException {

        DaemonThread thread = new DaemonThread();

        thread.setDaemon(true);

        thread.start();

        Thread.sleep(2000);

        System.out.println("我离开thread对象也不再打印了，也就是停止了！");

    }

}
