java timer for game

Question

I have created a game in java and now I just need to add a timer that allow the user to play under 60s. I have searched on internet and found the timer for swing and util packages. could you please just give me a method to be able to use it in my game???

Answer 1

System.currentMiliSeconds(); Save it at the beggining of the game. And then compare it: if(cm<(System.currentMiliSeconds()/1000-60)){System.exit(0);}

Answer 2

if you want something interactive you can use TimerTask and Timer classes:

class ExpireTask
{
  YourClass callbackClass;

  ExpireTask(YourClass callbackClass)
  {
    this.callbackClass = callbackClass;
  }

  public void run()
  {
    callbackClass.timeExpired()
  }
}

So now you've got a timer that fires calling timeExpired of another class. Now with a Timer you can schedule it:

...
Timer timer = new Timer();
timer.schedule(new ExpireTask(), 60000 /* 60 secs */);
...
