UML interfaces are used to_____________________?
Correct answer: A. specify required services for types of objects
- A. specify required services for types of objects
- B. program in Java, but not in C++ or Smalltalk
- C. define executable logic to reuse across classes
- D. define an API for all classes
Explanation
A UML interface specifies the services or operations that an object type promises to provide or requires, without prescribing the implementation. It is language-independent, so the Java-only option is incorrect, and it does not define executable reusable logic.
