Answer / harsha
Just a samll correction... Interfaces are part of
inheritance tree.
Inheritance is identified by both extends and implements
keywords.
Regarding the default constructor.. All the classes which
extend Object class will have a default constructor.
As we all know any interface cant extend Object class..
Interface cannot have default constructor.

yes it is bcz interfaces are not part of the inheritance tree.
after all u can define a contract between 2 different parties
using interfaces nothing more u can expect. its not actually
an executable construct
