Answer 2

Abstract methods, Default methods, and Constant fields, Static methods are inherited by a subinterface from its super interface.

A subinterface from its superinterface :

• A subinterface inherits all of the super interface's constant variables. If a subinterface declares a constant variable with the same name as the inherited constants, the new constant variable, regardless of type, conceals the inherited one.

• In addition, just as classes may inherit from other classes, a Java interface can inherit from another java interface.

• It is possible to assign a subinterface type reference variable to a super interface type reference variable.
