Java中的重启计时器

这对我来说很好用…您可以粘贴完整的代码和错误吗？

package snippet;import java.util.Timer;import java.util.TimerTask;public class Main {    public static Timer timer;    public static void main(String[] args) {        Main main = new Main();        main.myTimer(123, "127.0.0.1");    }    public void myTimer(final long MAC, final String ipAddress) {        TimerTask timerTask = new TimerTask() { @Override public void run() {     System.out.println("MAC: " + MAC + "ipAddress:" + ipAddress);     update(); }        };        timer = new Timer();        timer.schedule(timerTask, 1000);    }    public void update() {        TimerTask timerTask = new TimerTask() { @Override public void run() {     System.out.println("Updated timer"); }        };        timer.cancel();        timer = new Timer();        timer.schedule(timerTask, 2000);    }}

输出：

 MAC：123ipAddress：127.0.0.1 更新计时器
