Delete duplicate strings in string array

Question

I am making a program based on string processing in Java in which I need to remove duplicate strings from a string array. In this program, the size of all strings are same.

Answer 1

Set data structure will do automatically the job for. Most likely option for you will be HashSet, if you care about the order of elements look at TreeSet

List input = Arrays.asList(array);
Set unique = new HashSet<>(input);
