Something like this:
Vector bigVectorOStuff; // declared elsewhere, this contains your Strings
Vector uniqueEntries = new Vector();
Enumeration enum = bigVectorOStuff.elements();
String entry = null;
while (enum.hasMoreElements())
    entry = (String)enum.nextElement();
    if (!uniqueEntries.contains(entry))
         uniqueEntries.add(entry);
}That is, loop through the original Vector, getting each element out one at a time. Check to see if this element is in the other Vector, and if not, add it.
