Creating a pause or waiting effect in java program

问题

I am writing a simple fishing simulator game in Java. I wanted there to be a randomly generated waiting time after each cast. When the wait was over, a random event would occur(a fish would be caught, a fish would steel your bait, etc). I have heard allot of bad things about Thread.sleep() and was wondering what would work best for me in this situation.

currently I am using something like this

Random random = new Random();
long time = System.currentTimeMillis();
long difference = random.nextInt(9000);
boolean timeMet = false;

while(!timeMet){
   if((time + difference) <= System.currentTimeMillis())
      timeMet = true;
}

return event;

You could consider using a SwingTimer.

What have you heard bad about Thread.sleep(millis)? Using the cpu to keep busy for some period of time is quite wasteful.

Just use Thread.sleep(difference);
