1z0-829 Exam - Question 11

Question

Given the code fragment:Which set of class definitions compiles?

Examice · Accepted Answer

The correct answer is D. In Java, a sealed interface explicitly lists the permitted subclasses or implementing classes. The permitted subclasses or implementing classes must be declared as either sealed, non-sealed, or final. In the provided code fragment, since SInt is a sealed interface, any class or interface that extends or implements SInt must declare whether it is sealed, non-sealed, or final. Option D correctly shows that both interfaces Story and Art extend SInt and are marked as non-sealed, which is necessary to compile without errors.
