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 "";
}
Refactor:
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 "";
}
