  Code refactoring  Coderefactoring is the process of restructuring existing computer code—changing the factoring—without changing its external behavior. Refactoring improves nonfunctional attributes of the software. Advantages include improved code readability and reduced complexity; these can improve source- code maintainability and create a more expressive internal architecture or object model to improve extensibility.

  List of refactoringtechniques  Abstraction is one of the key concepts of object-oriented programming (OOP) languages. Its main goal is to handle complexity by hiding unnecessary details from the user.  Encapsulation is one of the fundamental concepts in object-oriented programming (OOP). It describes the idea of bundling data and methods that work on that data within one unit  Generalization, Generalization is the process of extracting shared characteristics from two or more classes, and combining them into a generalized superclass. Shared characteristics can be attributes, associations, or methods.

  2 benefits tothe activity of refactoring  Maintainability. It is easier to fix bugs because the source code is easy to read and the intent of its author is easy to grasp. It might be achieved by moving a method to a more appropriate class, or by removing misleading comments.  Extensibility. It is easier to extend the capabilities of the application if it uses recognizable design patterns, and it provides some flexibility where none before may have existed.

  Hardware refactoring While theterm refactoring originally referred exclusively to refactoring of software code, in recent years code written in hardware description languages (HDLs) has also been refactored.
