SOLID 原则详解
SOLID principles, introduced by Robert C. Martin, aim to make software design more flexible, maintainable, and scalable. The principles include Single Responsibility (S), Open/Closed (O), Liskov Substitution (L), Interface Segregation (I), and Dependency Inversion (D). Each principle is detailed with core ideas, explanations, code examples, and benefits. Following these principles leads to clearer, more concise code that is easier to test, maintain, and reuse. The principles enhance extensibility, reduce risks of code modifications, maintain inheritance consistency, improve code reliability, increase system stability, ensure correct polymorphism implementation, enhance flexibility, and reduce system coupling.
