Interface methods (pre-Java 8) are implicitly?

• A. public and abstract
• B. private and final
• C. protected and abstract
• D. default and public

Answer: (A)

Interface methods before Java 8 are implicitly public and abstract. This means any method you declare in an interface is a contract that must be implemented by any class that implements the interface, and there is no method body provided in the interface itself. The public nature ensures these methods are accessible through the interface reference, while the abstract nature enforces that the implementing class supplies the actual behavior. Private or protected modifiers aren’t used for interface methods in this era, and final would prevent overriding, which would defeat the purpose of an interface. Also, the ability to provide default method bodies (using the default keyword) didn’t exist until Java 8.
