Chapter 18.8, Problem 18.21CP

Explanation of Solution

Generic Interface:

“Yes”, an interface can be defined as generic.

Explanation:

Java Application Programming Interface (API) implements an interface as generic type.

Syntax for declaring generic interface is as follows,

  interface interface-name (list of type parameter)

• In the above syntax, interface is a keyword.
• interface-name is the name of an interface.
• list of type parameter indicates the comma separated list of type parameters.

Type arguments:

If generic interface is implemented, then it is necessary to define the type arguments.

The syntax for defining type arguments is as follows,

class class-name(list of type parameter) implements interface-name ( list of type arguments)

• In the above syntax, class, and implements are keywords...
