守护线程

package com.freeflying.thread.base;

public class DaemonThread {
	public static void main(String[] args) {
		try {
			DaemonThreadEx daemonThreadEx=new DaemonThreadEx();
			daemonThreadEx.setDaemon(true);//设置该线程为守护线程
			daemonThreadEx.start();//启动守护线程
			daemonThreadEx.sleep(5000);
			System.out.println("I leave thread,stop!!!");
		} catch (Exception e) {
			// TODO: handle exception
		}
	}
}
class DaemonThreadEx extends Thread{
	private int i=0;
	@Override
	public void run() {
		try {
			while(true) {
				i++;
				System.out.println("i="+i);
				Thread.sleep(1000);
			}
		} catch (Exception e) {
			// TODO: handle exception
		}
	}
}

结果：

i=1
i=2
i=3
i=4
i=5
i=6
I leave thread,stop!!!
