Substitute Algorithm

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 "";
        }
