How to error check string for LONG list of strings

Question

Hi All,
Let's say I want to compare a string variable with a long list of strings to see if it matches anything in that list. Is there some built-in function that will make this easy. Or should I do it the old fashioned way and load a string array with the list and then for loop through the array comparing each element?
Cheers,

I'm alittle weak at using interfaces. If the string I am trying to compare is (String grade), then how do I define my List to be ("A+", "A", "A-", "B+", "B", "B-", "C+", "C", .....). This is as far as I've got:
String grade = 'some letter to be compared'
String [] GradeList = new String [] {"A+", "A", "A-", "B+", "B", "B-", "C+", "C", .....};Maybe I could summarize what I meant using your example:
Set<String> PossibleGrades = new HashSet();
PossibleGrades.add("A+");
PossibleGrades.add("C");
String grade = "some letter to be compared";
if(PossibleGrades.contains(grade) )
   // do something...
