Objective Problems:
- Which of the following is NOT a design principle?
a) Interface Segregation Principle
b) Single Responsibility Principle
c) Dependency Inversion Principle
d) Keep It Simple, Stupid (KISS) Principle - The Interface Segregation Principle (ISP) suggests that:
a) Classes should implement all interfaces they use
b) A class should not be forced to depend on interfaces it does not use
c) Interfaces should be as large as possible to cover all use cases
d) Classes should have multiple responsibilities to ensure flexibility - According to the Dependency Inversion Principle (DIP), high-level modules should depend on:
a) Low-level modules
b) Abstractions (interfaces or abstract classes)
c) Details of implementation
d) Inheritance hierarchy - The DRY (Don't Repeat Yourself) principle advocates for:
a) Redundancy and code duplication for better performance
b) Reusing common functionalities and avoiding code duplication
c) Complex and convoluted code structures
d) Writing separate functions for each use case - The KISS (Keep It Simple, Stupid) principle suggests:
a) Avoiding simplicity to handle complex scenarios effectively
b) Building complex and convoluted code structures
c) Keeping code simple and straightforward
d) Over-engineering to accommodate future requirements - Design patterns are used to:
a) Provide step-by-step instructions for software installation
b) Solve specific design problems in software development
c) Document software requirements and specifications
d) Facilitate project management and team collaboration - Which SOLID principle suggests that a class should have only one reason to change?
a) Single Responsibility Principle (SRP)
b) Open-Closed Principle (OCP)
c) Liskov Substitution Principle (LSP)
d) Interface Segregation Principle (ISP) - Which principle suggests that high-level modules should not depend on low-level modules, but both should depend on abstractions?
a) Single Responsibility Principle (SRP)
b) Interface Segregation Principle (ISP)
c) Dependency Inversion Principle (DIP)
d) Keep It Simple, Stupid (KISS) Principle - The DIP (Dependency Inversion Principle) suggests that both high-level and low-level modules should depend on:
a) Each other
b) Abstractions (interfaces or abstract classes)
c) Details of implementation
d) Inheritance hierarchy - The purpose of the Singleton design pattern is to ensure that a class:
a) Has multiple instances for better performance
b) Has only one instance and provides a global access point to it
c) Implements all interfaces in the application
d) Allows dynamic instantiation and disposal of objects
Subjective Problems:
- Explain the Dependency Inversion Principle (DIP) with an illustrative example. Discuss how adhering to DIP facilitates flexibility and maintainability in software design.
- Design patterns are reusable solutions to common design problems. Choose any two design patterns (e.g., Singleton, Observer, Factory) and provide detailed explanations of their use cases and benefits in software development.
- Discuss the importance of adhering to the Single Responsibility Principle (SRP) in object-oriented software design. How does SRP enhance code maintainability, readability, and testability?
- Explain the Interface Segregation Principle (ISP) with a practical scenario. How can ISP lead to a more modular and cohesive codebase? Provide an example demonstrating the segregation of interfaces.
- The DRY (Don't Repeat Yourself) principle encourages code reusability and reduction of redundancy. Illustrate the concept of DRY with a real-world coding example. How does following DRY contribute to code quality and developer productivity?
