    Default [SOLVED] Duplicates in String Array

    I have a string array which I read from a file and I need to check for duplicates and return the number of elements which are unique. Is there a simple way of doing this?

    If I remember correctly, you could use the Arrays method asList(...) and use that List to create a HashSet (see HashSet's constructors). Then I believe the HashSet should contain all the unique Strings.
