Was this a compilation error or a runtime error? It sounds like you were trying to call a private method, selectPlayer(), from another class. It doesn't sound like the error had anything to do with testing whether LAST_SELECTED was null or not. You didn't show any code that actually called selectPlayer(). - Gordon
