Java Frustrations

Yesterday, I came across the following Java code (names changed to protect the innocent):

void processBalls(List balls) {

  //Saved blue balls for the end of the list
  List blueBalls = new ArrayList();
  int count = 0;

  //we only need a max of 12 balls here.
  for (int i = balls.size() -1;
      i > -1 && count < MAXIMUM_NUMBER_OF_BALLS; i--) {
    Ball ball = (Ball)balls.get(i);
    if (isBlueBall(ball)) {
      //don't process small blue balls
      if (!isSmallBall(ball)) {
        blueBalls.add(ball);
      }
    } else {
      processBall(ball);
      count++;
    }
  }
  //Put blue balls at the end if there is room
  for (int i = 0; i < blueBalls.size() &&
      count < MAXIMUM_NUMBER_OF_BALLS; i++) {
    Ball ball = (Ball)blueBalls.get(i);
    processBall(ball);
    count++;
  }
}

I was trying to express my frustration with this code to my pair, but my point wasn't getting across. So, I wrote the equivalent in Ruby:

def process_balls(balls)
  balls = balls.reverse
  balls = balls.select {|b| !is_blue(b)} +
    balls.select {|b| is_blue(b) && !is_small(b)}
  balls = balls.first(MAXIMUM_NUMBER_OF_BALLS)
  balls.each {|b| process_ball(b)}
end
