Chapter 11: Problem 8

If a method in a subclass has the same signature as a method in the superclass, does the subclass method overload or override the superclass method?

Short Answer

Expert verified

Answer: The subclass method with the same signature as the superclass method overrides the superclass method.

Step by step solution

Understand Method Overloading

Method overloading is a concept in object-oriented programming where we can have multiple methods with the same name, but different numbers or types of parameters. These methods are called overloaded methods.

Understand Method Overriding

Method overriding is a concept in object-oriented programming where a subclass provides a new implementation for a method that already exists in its superclass. The method in the subclass has the same name, return type, and arguments as the method in the superclass.

Compare Signatures

In this case, the exercise states that a method in a subclass has the same signature as a method in the superclass. Signature means the method name, return type, and the arguments (number and types). Since the signature of both methods is the same, this scenario represents method overriding.

Final Answer

The subclass method with the same signature as the superclass method does not overload the superclass method; it overrides the superclass method.
