    Question

    In object-oriented programming, when defining an

    interface method, which of the following statements is true regarding method parameters?
    A Interface methods can have parameters, but they cannot have return types. Correct Answer Incorrect Answer
    B Interface methods must have parameters defined with default values. Correct Answer Incorrect Answer
    C Interface methods can have parameters, but they must be implemented by classes that provide specific implementations. Correct Answer Incorrect Answer
    D Interface methods cannot accept any parameters and must be parameterless. Correct Answer Incorrect Answer
    E Interface methods can have parameters with variable length, but they cannot use standard data types. Correct Answer Incorrect Answer

    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.
