get possible instance/type of object
提问by machine
I have the problem that a given object could be one of several different objects (like files in a directory, that could be sound, image, text, ...) Is there the possibility to find out the type of the object beside from the 'instanceof' operator? Couse that would result in an endless if - then row ...
