implementations for its abstract methods. Java programs can use interfaces
to make it unnecessary for related classes to share a common abstract
superclass or to add methods to Object." This explains why we need
interfaces. By using protected methods in interfaces and therby restricting
the visibility you don't  get the above mentioned benefit. If your problem
is related to namespace, why don't you use Inner Interfaces ?
