Answer 5

https://en.wikipedia.org/wiki/SOLID

Single responsibility
Open–closed
Liskov substitution
Interface segregation
Dependency inversion

Single-responsibility principle (SRP) states that “[t]here should never be more than one reason for a class to change.” In other words, every class should have only one responsibility.

Open–closed principle (OCP) states that “[s]oftware entities … should be open for extension, but closed for modification.”

Liskov substitution principle (LSP) states that “[f]unctions that use pointers or references to base classes must be able to use objects of derived classes without knowing it. (Polymorphism)

Interface segregation principle (ISP) states that “[c]lients should not be forced to depend upon interfaces that they do not use.”

Dependency inversion principle (DIP) states to depend upon abstractions, [not] concretes.
