What is the impact of overloading and overriding on code maintainability?

Overloading and overriding can significantly affect code maintainability. Overloading allows methods to have the same name with different parameters, which can make code more intuitive. However, excessive overloading can lead to confusion. Overriding, on the other hand, enables a subclass to provide a specific implementation of a method already defined in its superclass, promoting code reuse but potentially complicating the inheritance structure.

Can you give examples of when to use overloading?

Sure! Overloading is useful when you want to perform similar operations with different types of inputs. For example, a method named add could be overloaded to handle both integers and floating-point numbers, allowing for flexibility in calculations.

What about overriding? When should I use it?

Overriding is best used when you want to change or extend the behavior of a method in a subclass. For instance, if you have a base class Animal with a method makeSound, you can override it in subclasses like Dog or Cat to provide specific sounds.

Are there any downsides to using these techniques?

Yes, there are downsides. Overloading can lead to ambiguity if not managed properly, making the code harder to read. Overriding can introduce complexity in the class hierarchy, making it difficult to track which method is being called, especially in large systems.
