[flexcoders] Does AS3 support Strong Typing, Class casting or intrinsics

[dorkie dork from dorktown]

I'm not sure if I'm using the right term (please correct me) but does AS3
support strong typing? In Java it is:

strong type would be telling that ArrayCollection the  type of object you
are going to store in it. Like

Collection<UserObject> list = new Vector<UserObject>(10);

<-  In this statement I am telling java that the Collection will hold a
UserObject Class.
