Question

So I\'m working on a comparator problem and I can\'t figure out why the Array.sort in this first class is giving me the error of:

The method

Answer 1

Ignoring your actual problem with Arrays.sort vs. Collections.sort (that has been beautifully answered), it might be a good idea to implement a Comparator instead of casting your Objects in the compare method:

public class CalorieComparator implements Comparator {

  @Override
  public int compare(Edible o1, Edible o2) {        
    if (o1.getCalories() > o2.getCalories()) {
        return 1;
    } else if (o1.getCalories() < o2.getCalories()) {
        return -1;
    } else {
        return 0;
    }
  }
}
