The cheapest way would be to reset your Usednumber array to a new array of booleans somewhere (please don't start variable names with an upper case letter).

kind regards,

okay... but how do you restart the array to a new array of booleans. i can picture the possibilities but im not so sure. im thinking it like this. sorry for bad English


usednumberarray()

resetusednumberarray()
restart usednumberarray;

newgameJbutton()
{
usednumberarray()
}



restartJbutton()
{
resetusednumberarray();
}

is this valid?

Why no simply do:

Code:

---

usednumberarray= new boolean[10];

---

The new array has all its elements set to false.

Jos

Good; here's a little tip: set up your game class in a modular way; e.g.

Code:

---

public class Game {
  public Game( ... ) {
      initGame( ... );
      initGui( ... );
  }
  public void playGame() {
      ...
  }
  private void initGame( ... ) {
      // init your array here ...
  }
  ...
}

---

From your actionPerformed( ... ) method all you have to do is call the initGame( ... ) method that initializes your array (and probably other things too). Better create a lot of small methods instead of one big mess of a single 'god method'.

kind regards,

Jos
