Hi Raj,
val c:a=a
what is a here??
trait or object,
Its trait not object so
val c:a =new a
when you say val c=a what gets assigned is object a
because in scala like java class address is classn...@hashcode
for object objectna...@hashcode
I am not sure if it helps.
Please tell me if i understood the whole thing wrongly.
thanks,
