In computer programming and software design, code refactoring is the process of restructuring existing source code—changing the factoring—without changing its external behavior. Refactoring is intended to improve the design, structure, and/or implementation of the software (its non-functional attributes), while preserving its functionality.
The process of removing data clumps runs the risk of creating a different type of code smell (a data class, which is a class that only stores data and does not have any methods for actually operating on the data); however, the creation of the class will encourage the programmer to see functionality that might be included here as well.

In software engineering, the Extract Class refactoring is applied when a class becomes overweight with too many methods and its purpose becomes unclear. Extract Class refactoring involves creating a new class and moving methods and/or data to the new class.
(expression → function) replacing an expression with a function or algorithm (variable → assignment) replacing the value of a variable. (case) adding a case (or else) to an existing switch or if; Uncle Bob also explicitly stated: "There are likely others", [1] and [I] think that the priority list is language specific...
"Don't repeat yourself" (DRY), also known as "duplication is evil", is a principle of software development aimed at reducing repetition of information which is likely to change, replacing it with abstractions that are less likely to change, or using data normalization which avoids redundancy in the first place.
Common refactoring activities are changing variable names, renaming methods, moving methods or whole classes and breaking large methods (or functions) into smaller ones. Agile software development methodologies plan for regular (or even continuous) refactoring making it an integral part of the team software development process .
The class defines the data format or type (including member variables and their types) and available procedures (class methods or member functions) for a given type or class of object. Objects are created by calling a special type of method in the class known as a constructor .
