无法同时运行两个语音和一个线程

Question

我试图制作一个时钟，如果

如何同时运行警告语音和时钟，使时钟在播放警告语音（）时不会停止？

语音代码：

private void warningVoice() {
    System.setProperty("freetts.voices", "com.sun.speech.freetts.en.us.cmu_us_kal.KevinVoiceDirectory");
    vm = VoiceManager.getInstance();
    voice = vm.getVoice(SayWhat);
    voice.setStyle("robotic");
    voice.setVolume(200);
    voice.allocate();
    String writing; 
    writing = "You Have" + lblMinute.getText() + "Minutes Left";
    try {
        voice.speak(writing);
    }
    catch (Exception ex) {
    }
}

时钟代码：

private void showTime() {
    timer = new Timer(1000, new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            second--;
            second_format = String.format("%02d", second);
            minute_format = String.format("%02d", minute);

            lblSecond.setText(String.valueOf(second_format));

            if (second == -1) {
                second = 59;
                minute--;
                second_format = String.format("%02d", second);
                minute_format = String.format("%02d", minute);
                lblSecond.setText(String.valueOf(second_format));
                lblMinute.setText(String.valueOf(minute_format));
             
               /*This is the problem line*/
                if (minute <= 10) {
                    warningVoice();
                }
                
                if (minute == 0) {
                    timer.stop();
                    
                    second = 60;
                    minute = 25;
                }
            }
        }
    });
    timer.start();
}

您应该研究util Timer类和timertask，然后可以通过以下方式大大简化代码：

private void warningVoice(long millisLeft) {
    //obviously replace this with your voice code
    System.out.println("You have " + TimeUnit.MILLISECONDS.toMinutes(millisLeft) + " minutes left");
}

public static void main(String[] args) throws Exception {
    Timer timer = new Timer();
    long taskTimeInMillis = TimeUnit.MINUTES.toMillis(25);
    final long warningTimeInMillis = TimeUnit.MINUTES.toMillis(10);
    long sendWarning = taskTimeInMillis - warningTimeInMillis;

    TimerTask warningTask = new TimerTask() {
        public void run() {
            warningVoice(warningTimeInMillis);
        }
    };

    timer.schedule(warningTask, sendWarning);
}
