How does EnumSet compare to traditional bit flags?

  1. More expressive and efficient

  2. Less efficient

  3. Not as expressive

  4. Equally expressive but more efficient

The correct answer is: More expressive and efficient

EnumSet is a specialized Set implementation in Java that is specifically designed to work with enumeration types. It offers more expressive capabilities compared to traditional bit flags which only offer bitwise operations. EnumSet also performs more efficiently than bit flags as it uses optimal data structures and algorithms for working with enum types. Option B is incorrect because EnumSet is actually more efficient than bit flags. Option C is incorrect as EnumSet is more expressive. Option D is incorrect as EnumSet is both more expressive and efficient compared to traditional bit flags.
