Source code refactoring can improve the quality and maintainability of your project by

restructuring your code while not modifying the runtime behaviour. Visual Studio Code

supports refactoring operations $($refactorings$)$ such as Extract Method and Extract

Variable to improve your code base from within your editor.

Next, you will experiment with refactoring on Visual Studio. As shown in Study $6,$ it is

possible to share common code between related classes by inheriting shared code

from a superclass. Extract Method refactoring is used to avoid duplicating code $($a

maintenance headache$),$ which enables you to select source code that you'd like to

reuse elsewhere and pull it out into its own shared method.

NOTE: Refactoring support for programming languages Java and Python is provided

through VS Code extensions that contribute to language services. Make sure to install

the Extension Pack for Java beforehand.
