Edit Question
Title
Body
Just for review, can someone quickly explain what prevents this from working (on compile): private HashSet data; ... public DataObject[] getDataObjects( ) { return (DataObject[]) data.toArray(); } ...and what makes this the way that DOES work: public DataObject[] getDataObjects( ) { return (DataObject[]) data.toArray( new DataObject[ Data.size() ] ); } I'm not clear on the mechanism at work with casting (or whatever it is) that makes this so.
