Answer 1

If you actually want to add/remove items from an array, may I suggest a List instead?

String[] firstArray = {"test1","","test2","test4",""};
ArrayList list = new ArrayList();
for (String s : firstArray)
    if (!s.equals(""))
        list.add(s);

Then, if you really need to put that back into an array:

firstArray = list.toArray(new String[list.size()]);
