重构Java代码

有人能告诉我如何重构下面的代码吗。基本上，我有一个定时器功能，我重复使用。所以我想把计时器放到一个通用函数中

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

public class App {
    private volatile boolean a = false;
    private volatile boolean b = false;
    private volatile boolean c = false;
    public static void main(String[] args) {
        App app = new App();
        app.m1();
    }

    private void m1() {
        // m2() should not take more than specified time in timer
        Timer timer = new Timer();
        timer.schedule(new TimerTask() {            
            @Override
            public void run() {
                if(a){
                    System.out.println("m1 Do nothing");
                }
                else{
                    System.out.println("m1 Timeout exception");
                }
            }
        }, 2*60*1000);
        a=m2();
        System.out.println("Blah");
    }
    private boolean m2() {
        // Killing some time with sleep
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        //m3() should not take more than specified time in timer
        Timer timer = new Timer();
        timer.schedule(new TimerTask() {            
            @Override
            public void run() {
                if(b){
                    System.out.println("m2 Do nothing");
                }
                else{
                    System.out.println("m2 Timeout exception");
                }               
            }
        }, 1*60*1000);
        b = m3();
        System.out.println("Blah Blah");
        return true;
    }
    private boolean m3() {
        //m4() should not take more than specified time in timer
        Timer timer = new Timer();
        timer.schedule(new TimerTask() {            
            @Override
            public void run() {
                if(c){
                    System.out.println("m3 Do nothing");
                }
                else{
                    System.out.println("m3 Timeout exception");
                }           
            }
        }, 20000);
        c=m4();
        System.out.println("Blah Blah Blah");
        return true;
    }
    private boolean m4() {
        try {
            Thread.sleep(10);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        return true;
    }
}

谢谢你的帮助。我不是在寻找代码帮助。想知道您对最小化代码的想法。

这个问题属于这些计时器之间的区别吗？@Jens我想问题的关键是没有太大区别。@immibis肯定有区别。如果不需要，则不需要3个计时器。@Jens他们检查不同的变量，并打印不同的消息。
