What are some real-world examples of method overriding and overloading?

Method overriding occurs when a subclass provides a specific implementation of a method that is already defined in its superclass. For example, consider a class Animal with a method makeSound(). A subclass Dog can override this method to return 'Bark'.

Method overloading, on the other hand, allows a class to have multiple methods with the same name but different parameters. For instance, a class Calculator might have a method add(int a, int b) and another add(double a, double b).

Can you give me more examples of method overloading?

Sure! In Java, you might have a class Display with methods like show(int a), show(String b), and show(double c). Each method has the same name but takes different types of parameters, demonstrating method overloading.

What about method overriding? Any other examples?

Absolutely! Another example of method overriding is in a class hierarchy of Vehicle. If you have a superclass Vehicle with a method start(), subclasses like Car and Bike can override this method to provide their specific starting mechanisms.

How do these concepts apply in real-world applications?

In real-world applications, method overriding allows for dynamic polymorphism, enabling a program to decide at runtime which method to execute. Method overloading enhances code readability and usability, allowing developers to use the same method name for different functionalities.
