Single responsibility,
Open closed principle,
Liskov substitution principle,
Interface segregation principle

These are five prnciples while doing class design

SRP	Single Responsibility Principle	A class should have one, and only one, reason to change.
OCP	Open Closed Principle	You should be able to extend a classes behavior, without modifying it.
LSP	Liskov Substitution Principle	Derived classes must be substitutable for their base classes.
ISP	Interface Segregation Principle	Make fine grained interfaces that are client specific.
DIP	Dependency Inversion Principle	Depend on abstractions, not on concretions.
