Chapter 3, Problem 1RE

Explanation of Solution

Public Interface of “Counter” class:

  • The public interface of the “Counter” class includes “click()”, “getValue()” and “reset()” methods.
  • The public interface specifies the functionality related to the class but it doesn’t include any information about the process of implementation of the functionality.

Explanation of Solution

Public interface differed from class implementation:

  • The process of implementation of the functionality related to “Counter” class will not be explained.
  • The implementation of a class is the code used in the tasks to support the functionality of the class.
