Question
In object-oriented programming, when defining an
interface method, which of the following statements is true regarding method parameters?Solution
In object-oriented programming, an interface defines a contract that specifies a set of methods that implementing classes must provide. Interface methods can indeed have parameters, which are used to pass information to these methods when they are called. However, while an interface method specifies what parameters are required, it is the responsibility of the classes implementing the interface to provide the actual method bodies and handle these parameters appropriately. This means that while the interface outlines the method signatures, including their parameters, the concrete implementations in the classes are required to define how these parameters are used and processed. This approach ensures that any class implementing the interface adheres to the expected method signature and behavior, providing consistency across different implementations.
