for a project for school we have to make a game

but there is a timelimit while playing the game, the player can only play for 3 minutes

I have allreayd googled for quite a while, but I still can't find how to

so basicly my problem is:

1 how can I run a clock/timer?
2 how can I make it run in the background of a program so it will only influence the gameplay when the 3 minutes barriere is reached

To start with, you want to get the system time when the game starts. Then, for every action, you can check the time and compare it to the time when the game started.

To check system time I guess this method in the Calendar class works good:

int time = Calendar.getInstance( ).getTimeInMillis( );

Then, to get it to run in the background you need to instantiate a new thread.

Something like:

public class Timer implements runnable{
  public void run(){
    Calendar finish = Calendar.getInstance();
    finish.add(Calendar.MINUTE, 3);
    while(true){		
      if(finish.before(Calendar.getInstance())){
	System.out.println("You've been playing for three minutes now");
	break;
      }
    }
  }
}

Thread t = new Thread(new Timer()); t.start();
