java - 我需要知道如何在用户设置时间后调用闹钟声音

Question

我已经尝试了 2-3 天来找到一种方法来调用 play() 方法，这是我的警报声音，但没有真正成功...我尝试过 while 和 for 循环、带有 boolean 标志的新 TimerTasks，但没有成功...警报声音在满足用户输入时不会触发，所以我可以请更有经验的人告诉我我做错了什么吗？

这是我的命令类，其中放置了闹钟声音，它本身连接在主类 ClockGui 中

 package Clock;

 import java.io.*;
 import java.text.DecimalFormat;
  import java.util.Calendar;
  import java.util.Timer;
 import java.util.TimerTask;

import javax.swing.*;
import sun.audio.*;

public class Commands {
ClockGui gui;
Time clock;
Timezones zone;
 DecimalFormat df = new DecimalFormat("00");
int hour1 ;
int min1 ;
int sec1;

boolean alarmOn = false;


public Commands (ClockGui gui) {
     this.gui = gui;
     zone = new Timezones(gui);
     clock = new Time(gui);

}

public void setAlarm() {
      hour1 = Integer.parseInt(JOptionPane.showInputDialog("Set the hour of the alarm \n in the form of '00' :"));
      min1 = Integer.parseInt(JOptionPane.showInputDialog("Set the minutes of the alarm \n in the form of '00' :"));
      sec1 = Integer.parseInt(JOptionPane.showInputDialog("Set the seconds of the alarm \n in the form of '00' :"));
      gui.alarm1.setText("" + df.format(hour1) + " : " + df.format(min1) + " : " + df.format(sec1));
      Timer timer2 = new Timer();
       TimerTask task2 = new TimerTask() {
           public void run(){
               Calendar timeNow = Calendar.getInstance();
               int hours = timeNow.get(Calendar.HOUR_OF_DAY);
               int mins = timeNow.get(Calendar.MINUTE);

               if (hours == hour1 && mins == min1) {
                   alarmOn = true;
               }

           }
       };
       timer2.scheduleAtFixedRate(task2,0,1000);



 }

public void play() {
if(alarmOn == true){

    InputStream sound;
    try {
        sound = new FileInputStream(new File("C:\\Users\\User\\workspace\\Alarm Clock\\src\\Clock\\sound.wav"));
        AudioStream alarm = new AudioStream(sound);
        AudioPlayer.player.start(alarm);
    } catch (Exception e){
        JOptionPane.showMessageDialog(null, e);
    }
}

}

这是我的主课

  JTextField timeZone = new JTextField(6);
  JTextField alarm1 = new JTextField(7);
  JButton alarm = new JButton("Set Alarm");
  JButton reset = new JButton("Reset");


public ClockGui() throws IOException   {
    clock = new Time(this);
    command = new Commands(this);
    zone = new Timezones(this);
    makeFrame();
    if (command.alarmOn == true){
        command.play();
    }


}

public static void main(String[] args) throws IOException   {

    new ClockGui();



}

只需删除 alarmOn 变量并调用 play()，而不是在 TimerTask 中设置 alarmOn = true。
