Consider a car manufacturer that can make cars that comes with many different, optional features. A customer first chooses a basic version of the car, and he can add in any features that he likes, e.g. leather seats, sports rims, heated steering wheel, etc.. Design a software system that can create a car with any combination of features easily without changing the structure of any software classes. What design pattern will you use? Draw the class diagram. You may give your classes any names that you like.

car manufacturer decides to introduce different trim levels of the car where each trim level corresponds to a pre-determined set of features a fixed number of pre- selected features). For example, there may be three trim levels, Basic, Extra and Ultimate, which contains 5, 10 and 20 pre-selected features respectively. However, the car manufacturer wants to retain the flexibility of being able to change what features go into which trim. For example, in the 2023 model year, the Basic trim does not have leather seats, but in the 2024 model year, the manufacturer may want to include leather seats in the Basic trim. The customers cannot choose what features to be included; they can only choose which trim level to buy. Design the software system so that there are fixed trim levels for the customer, and the manufacturer can easily change what features go into which trim level at any time. What design pattern(s) will you use? (HINT: finite number of combinations = finite number of 'states'). Draw the Class diagram. Include all attributes or operations that are essential to the Design Pattern(s) you have chosen. Any other attributes or operations are optional. You can give them any names that you like.
