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

How about using a List:

wordList = outString.toString().split(", ");
List finalList = new ArrayList();
for(String val : wordList) {
  if(!finalList.contains(val)) {
    finalList.add(val);
  }
}

A Set would be more efficient, however. If you can't use a List or a Set, and you are forced to remove the duplicates, then you will have to loop through the array each time, which will perform horribly.
