Doing something at a specific time of day

Question

Hi all,
Basically what I am doing is an alarm clock, to wake me up to some MP3s. It all works fine.
My only concern is the following:
     private Thread tTimeCheck = new Thread() {
          public void run () {
               while (true) {
                   cal = new GregorianCalendar();
                   int hour24 = cal.get(Calendar.HOUR_OF_DAY);
                   int min = cal.get(Calendar.MINUTE);
                   if (hour24 == JSelectHour.getValeur() && min == JSelectMinute.getValeur()) {
                        playMusic = true;
                   } else {
                        playMusic = false;
                   try {
                        t.sleep(1000);
                   } catch (InterruptedException e) {
     };Is it unefficient to check every second, to see if the time of day is equal to the set time on the alarm clock? It seems to me that there has to be a better way to do this.

Answer 1

Thank you for your reply.
This is my thread that plays the music.
while (true) {
   if (playMusic && jpnl.getAlarmStatus() == 1) {
       testPlay("C:/Documents and Settings/Seb/Desktop/Music/01-nirvana-smells.like.teen.spirit.mp3"); //hardcoded for now
}testPlay is executed the the entire song plays before the next iteration.
Next step: I'll look to put this in the taskbar (windows tray / whatever it's called), never done that before =)
Thanks,
