elect the correct answerWhich of the following reference types cannot be generic?OptionsInner classInterfaceAnonymous inner classAll of the mentioned

To determine which reference types cannot be generic, let's analyze the provided options:

1. Inner Class: Inner classes in Java can be generic. You can define an inner class with type parameters.

2. Interface: Interfaces can also be generic. You can declare a generic interface with type parameters.

3. Anonymous Inner Class: Anonymous inner classes cannot be generic because they do not have a name and thus cannot have type parameters defined. They are created in a specific context and cannot be reused like named classes.

4. All of the Mentioned: This is a blanket option that implies that all the other options cannot be generic, which is not true as discussed above.

Final Answer

The correct answer is Anonymous inner class.
