What is code refactoring, and why is it important in Java development?
Code refactoring is the process of improving the internal structure of existing code without changing its external behavior. Itâ€™s important because it makes the code easier to maintain, more efficient, and less prone to bugs.
Thatâ€™s correct. Refactoring improves code readability and maintainability while preserving its functionality.
Can you explain how you would approach refactoring a large Java application with minimal risk of breaking existing features?
