Removing spaces from an ArrayList

[Mr Smiggins]

I'm trying to make a method that removes all cells that are just spaces from an ArrayList. So far I have this:

public ArrayList removeSpace()
    {
        Iterator<String> it = array.iterator();
            while (it.hasNext())
            {
                if (it.next().equals(" "))
                {
                    it.remove();
                }
            }
        return array;

This unfortunately seems to return a completely empty ArrayList. Any ideas?
Thanks in advance

Well I'm certainly an idiot. It actually worked fine. Always a good idea not to start off with an empty array if you don't want to end up with one.

A very good idea indeed. Good to know that you found the problem yourself.


Good luck with the rest of it.
