java任务调度Timer简单例子

1、创建类TimerTest

import java.util.Timer;
import java.util.TimerTask;

public class TimerTest {

    private final Timer timer = new Timer();
    public void start() {
        timer.schedule(new TimerTask() {
            public void run() {
                System.out.println("定时任务");
            }

        }, 0, 2 * 1000);
    }

}

2、运行测试类test

public class Test {
    public static void main(String[] args){
        // TODO Auto-generated method stub

        TimerTest aa = new TimerTest();

        aa.start();

    }

}
