Answer Posted / rambabu gonela
java does't support multiple inheritance..to overcome this
problem.. java introduce new concept that is interface,
we cannot intantiate both interface and abstractclass.1)by
default in interface variables are public,static and final,
in abstract class we have to declare explicitly 2) methods
in interface public,nonstatic and abstract,where as in
abstract class we have to give....
3)we can implements more than one interfaces.. but we can
extends only one class..
