What does the term 'method overloading' refer to?

• A. Defining two methods with the same name and return type
• B. Defining multiple methods with the same name but different parameters
• C. Creating a method that overrides another method
• D. Defining methods that can return different types based on context

Answer: (B)

Method overloading refers to defining multiple methods with the same name but different parameters. This concept allows a class to have more than one method with the same name, enabling them to perform similar functions while accepting different types or numbers of arguments.

The key aspect of method overloading is the difference in the method signatures, which consist of the method name and the parameter list. The method signature is used by the compiler to differentiate between the methods. For instance, you can have one method that takes an integer parameter and another that takes a double parameter, both having the same name, which enhances the readability and usability of the code.

This flexibility allows developers to implement various functionalities under the same method name, catering to different input scenarios while keeping the interface clean and understandable. Hence, when the method is called, the compiler determines which specific method to invoke based on the argument types and numbers passed to it.

The other options describe various concepts that are not applicable to method overloading. For example, defining two methods with the same name and return type does not specifically address the requirement of differing parameters, which is the essence of method overloading. Similarly, creating a method that overrides another method refers to method overriding, which is fundamentally different as it deals with inheritance and
