SOLID 原则详解
SOLID principles, including Single Responsibility Principle (S), Open/Closed Principle (O), Liskov Substitution Principle (L), Interface Segregation Principle (I), and Dependency Inversion Principle (D), aim to improve software design by promoting flexibility, maintainability, and extensibility. Each principle is detailed with examples and benefits. For example, adherence to Single Responsibility Principle leads to clearer, more concise code with reduced coupling between classes. Similarly, following Open/Closed Principle enhances code scalability and stability by favoring extension over modification. Liskov Substitution Principle ensures consistency and reliability in inheritance hierarchies, while Interface Segregation Principle increases code flexibility and reusability by avoiding unnecessary method implementations. Lastly, Dependency Inversion Principle emphasizes abstract dependencies over concrete ones, promoting decoupling and control inversion for better code maintenance and scalability.
