  constraints.gridx = x;
  constraints.gridy = y;
  gridbag.setConstraints(c, constraints);
  add(c);
 }
 public boolean handleEvent(Event event) {
  if(event.target instanceof TextField && event.id == Event.ACTION_EVENT) {
   if(state == BET){
    updateBet();
    return true;
   }
  }else if(event.target instanceof Button && event.id == Event.ACTION_EVENT) {

    }
   }
  }
  return false;
 }
 public void updateBet() {

  betLabel.setText("Bet: ");
  try {
   Integer i = new Integer(betField.getText()); 
   bet = i.intValue();
  } catch (NumberFormatException ex) {
   bet = 1;
  }
  betField.setText(String.valueOf(bet));
  initialDeal();
  if(playersHand.blackjack()) playerWins();
  else state = PLAY;
 }
 void initialDeal() {
  playersHand = new Hand();
  dealersHand = new Hand();
  for(int i = 0;i dealersHand.bestScore()) playerWins();
  else if(playersHand.bestScore() < dealersHand.bestScore()) dealerWins();
  else tie();

Though it is better if such programs are uploaded instead.
