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

You probably want to set t back to false after pulling the value you want:

if(t)
{
     wordList1[i]=wordList[i];
     t = false;
}

Also this:

if((wordList[i]!=wordList[j])&&(j>i))

Will always return true since strings are immutable (unless you compared a string to an exact reference of itself which you disallow with j>i). You need to change it to say this:

if (!(wordList[i].equals(wordList[j]))&&(j>i))

Using .equals will compared that they contain the same string, not that they point to the exact reference of a string.

Not sure if that's the only problems or not, a bit unclear from what's given.
