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.

Answer / madhu
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
