Java Coding Problems

Day 3 (filtering melons by type and weight)

Things are getting even worse. Mark has now asked us to add a new filter that filters melons by type and weight, and he needs this quickly. However, the quickest implementation is the ugliest. Check it out:

public static List<Melon> filterByTypeAndWeight(    List<Melon> melons, String type, int weight) {  List<Melon> result = new ArrayList<>();  for (Melon melon: melons) {    if (melon != null && type.equalsIgnoreCase(melon.getType())         && melon.getWeight() == weight) {      result.add(melon);    }  }  return result;}

In our context, this is unacceptable. If we add a new filter criterion here, the code will become hard to maintain as well as prone to errors.
