What do you mean when you say should test bounds


Well if you try and get something from the ArrayList when it's empty or from an index that is empty you're going to get an error: so make sure the ArrayList size() is greater than the index being accessed before actually calling get Wink

Strictly speaking in the code you post you won't need it as you're calling get from a loop that iterates over the length of the ArrayList, but there may be times when you want to get an individual Panel by its id and that's when not checking bounds might bite you.

And yes you will need a Component class - I guess PhiLho's code assumes 'Component' as a GUI element.  In your case I suspect you want this to be either a parent class for all your components or an Interface (could be empty) that they all implement.
