What does Overloading a Method mean?

• A. Providing two methods with identical names and identical signatures.
• B. Giving two methods the same name but different method signatures.
• C. Overriding a method in a subclass.
• D. Having a method that returns a different type than declared.

Answer: (B)

Overloading a method means having multiple methods with the same name but different parameter lists. The “signature” of a method includes its name and the types (and often the order) of its parameters. Because the parameter lists differ, the compiler can tell which version to call based on the arguments you pass. That’s why the best description is: giving two methods the same name but different method signatures. For example, methods named the same might be foo(int) and foo(String), and the correct one is chosen by the argument you supply. Returning a different type alone doesn’t create a new, distinct method, and overriding is when a subclass provides a new implementation for a method with the same signature in a superclass.
