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.
