Consider designing an online gift store that delivers various gift items in a variety of ways, such as direct pick-up from the store, delivery by its own logistics team, or delivery by other delivery partners. To support the delivery process, an interface DeliveryProcessing is being designed, which is further implemented by the classes that provide the implementation for specific delivery processes. The interface DeliveryProcessing specifies the methods to be implemented by any delivery class, and those are packageOrder(), notifyCustomer(), bookDeliveryPartner() and deliver(). The online gift store also has digital gift items like gift coupons, software games, etc., and for delivering these items, most of the methods in the interface DeliveryProcessing are not relevant. However, since the interface DeliveryProcessing needs to be implemented by any delivery class, delivery classes for digital gift items also need to implement the methods from DeliveryProcessing which are not at all relevant to those items.
Identify the SOLID principle that is missing from the design process.
Single responsibility principle
Open-close principle
Liskov substitution principle
Interface segregation principle
Correct answer
Interface segregation principle
An organization provides its employees with a mobile app that allows them to apply for leave. To select dates, it pops out a calendar; however, the calendar cannot highlight the holidays separately. As a result, there is a huge chance that an employee will apply for leaves on holidays. Which of the following heuristics of UI evaluation is missing in the mobile app?
Prevent errors
Recognition over recall
Provide help
Flexibility
Correct answer
Prevent errors
Suppose a job portal has a class Applicant for representing the candidates applying for jobs. Class Applicant has a few mandatory fields (like name, contact number, email) and a large number of optional fields (like experience, passport number, PAN number), which necessitates the designer to write a large number of constructors to instantiate the object of Applicant class (one constructor with only initializing all the mandatory fields and a number of constructors for different numbers and different combinations of optional fields along with all mandatory fields). Which of the following design patterns can be best suited for solving the problem of creating a large number of constructors?
Factory design pattern
Builder design pattern
Adapter design pattern
Facade design pattern
Correct answer
Builder design pattern
