An Effort to Improve Cohesion Metrics Using Inheritance

1.2.Class Cohesion: Classes are the fundamental units of object-oriented programs, and provided as the units of encapsulation promoting their modifiability and reusability. Class cohesion measure quality of classes by measuring binding of the elements defined with in the class. Inherited instance variables and inherited methods are not considered. Member methods are elements of a class and perform a common task and allow you to systematize class reasonably. Cohesiveness of a class depends upon its representation of its object as single, meaningful data abstraction. Cohesion of a class is rated as separable if its objects signify various unconnected data abstractions combined in one ne object. In this case instance variables and methods of class are partitioned into sets such that no method of one set uses instance variable or invoke method of a different set. For example if you have ten methods that act as utilities for network operations, you can very well split the class into two classes: one serving the utilities and the other, network operations. After split each separated class represent single data abstraction.
