What is code refactoring, and why is it important in Java development?
Refactoring is changing the functionality of a program to improve its design. Itâ€™s important because it helps developers add new features quickly by making the code more modular.
Thatâ€™s partially correct. Refactoring doesnâ€™t change the functionality but improves the internal structure, which in turn helps to add features more easily.
Can you give an example of a code refactoring technique that helps in making the code more modular without changing its behavior?
