Removing duplicate strings from an array?

Question

How can I remove duplicate strings from a string array without using a HashSet?

I try to use loops, but the words not delete.

StringBuffer outString = ne         


        

Answer 1

Iterate through the array, and store in an auxiliary int[] or List the indexes of duplicates that you find with your two for's.

Create a new Array, with size equal to the original one minus the size of the repeated Strings.

Iterate through your original array, if the index isn't on your auxiliary list, set it to your new Array.
