Describe the principles of SOLID design in Object-Oriented Programming.
Answer:
- SOLID Principles:
- S – Single Responsibility Principle (SRP): A class should have only one reason to change, meaning it should have only one responsibility or job.
- O – Open/Closed Principle (OCP): Software entities should be open for extension but closed for modification. This allows for adding new functionality without modifying existing code.
- L – Liskov Substitution Principle (LSP): Subtypes should be substitutable for their base types without affecting the correctness of the program.
- I – Interface Segregation Principle (ISP): Clients should not be forced to depend on interfaces they don’t use. Interfaces should be specific to the client’s needs.
- D – Dependency Inversion Principle (DIP): High-level modules should not depend on low-level modules. Both should depend on abstractions. Abstractions should not depend on details; details should depend on abstractions.
