finding out weather an object extends a certain class

[hgwoss]

I know that I can find out an object's classname with
getClass().getName()

However, I do not know how to find out weather the object extends a
certain Class.

Any help is very much appreciated.

You're expressing yourself incorrectly but I suppose you want this:
if(object instanceof Class){...}

Look up the keyword/operator:

instanceof

(with that exact case and spelling).
