Which of the following is poor design?
a. A data field is derived from other data fields in the same class.
b. A method must be invoked after/before invoking another method in the same class.
c. A method is an instance method, but it does not reference any instance data fields or invoke instance methods.
d. A parameter is passed from a constructor to initialize a static data field.
abcd A is not good because there is no need to define the data field if it can be derived from other data fields. B is not good because it is highly problematic to impose any order for invoking the methods. C is a bad design because in this case the method should be defined as static. D is not good because a static data field is now tied to the creation of a specific object, which should not be the case.
