Which principles of object-oriented programming intersect with the SOLID principles?

The SOLID principles are closely related to the core principles of OOP:

• Inheritance: Related to the Liskov Substitution Principle (LSP), which requires that objects of subclasses can replace objects of their base classes without affecting the correctness of the program.
• Polymorphism: Also closely related to LSP, as polymorphism allows handling objects of different classes through a common interface, which is important for maintaining substitution.
• Encapsulation: Indirectly supported by the Single Responsibility Principle (SRP) and the Interface Segregation Principle (ISP). SRP helps group related data and behavior, while ISP ensures clients only have access to the interfaces they actually need.
• Abstraction: Related to the Dependency Inversion Principle (DIP). DIP encourages dependence on abstractions rather than concrete implementations, facilitating the creation of flexible and easily extendable systems.

Thus, the SOLID principles complement and guide the application of OOP principles to create more understandable, flexible, scalable, and maintainable code.
