Question

List three "bad smells" signaling that your code probably should be refactored?

1) Long method
2) Large class
3) Duplicate code

Answer 1

Three bad smells that signal your code probably should be refactored are: long method, large class, and duplicate code.

Step-by-step explanation:

Three bad smells that signal your code probably should be refactored are:

1. Long method: When a method is too long, it becomes difficult to understand and maintain. Breaking it down into smaller, more focused methods can improve readability and maintainability.
2. Large class: Classes that have too many responsibilities and functions can become bloated and hard to manage. Splitting them into smaller, more cohesive classes can make them easier to understand and test.
3. Duplicate code: Repeating the same code in multiple places is a strong indicator that refactoring is needed. Extracting the duplicate code into reusable functions or classes can help improve code clarity and reduce maintenance.
