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

In your inner loop, initialize j = i + 1

if(wordlist[i] != null && wordlist[i].equals(worldlist[j])) { wordlist[j] = null; }

...and then compact the array when you're finished to remove all null values
