Timer类的学习

1.首先创建一个类继承TimerTask,实现run方法;

public class MyTimerTask extends TimerTask{
    private  String name;

    public MyTimerTask(String name) {
        this.name = name;
    }

    public void run() {
        System.out.println("current name is:"+name);
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

2.再创建一个测试类,new 一个Timer对象,调用schedule方法,实现定时任务

public class MyTimer {
    public static void main(String[] args) {
        Timer timer = new Timer();
        MyTimerTask timerTask = new MyTimerTask("lili");
        timer.schedule(timerTask,2000L,1000L);
    }
}
