Substitute Algorithm

You want to replace an algorithm with one that is clearer.

Replace the body of the method with the new algorithm.

String foundPerson(String[] people){
  for (int i = 0; i < people.length; i++) {
    if (people[i].equals ("Don")){
      return "Don";
    }
    if (people[i].equals ("John")){
      return "John";
    }
    if (people[i].equals ("Kent")){
      return "Kent";
    }
  }
  return "";
}

String foundPerson(String[] people){
  List candidates = Arrays.asList(new String[] {"Don", "John", "Kent"});
  for (int i=0; i<people.length; i++)
    if (candidates.contains(people[i]))
      return people[i];
  return "";
}
