[josm-dev] Java question

[David Earl]

My Java knowledge has let me down and I haven't been able to frame a 
suitable Google query. Can someone tell me how in Java I test whether 
some object is a subclass or superclass of some class (or other object)?

I know how to ask if something is an instance of a particular class 
(o.class() == C.class) but if o could be a subclass of c how do express 
this?

TIA,
David
