What is 'values()' in the context of enum classes?

  1. Instance method

  2. Class method

  3. Static method added by compiler

  4. None of the above

The correct answer is: Static method added by compiler

In the context of enum classes, 'values()' is a static method that is automatically added by the compiler. This method allows you to retrieve an array of all the possible values of the enum type. Option A is incorrect because 'values()' is not an instance method, meaning it does not require an instance of the enum class to be called. Option B is incorrect because it is not a class method that needs to be called on the class itself. Option D is incorrect because 'values()' is in fact a valid option.
