SOLID principles

SOLID principles
S stands for SRP (Single responsibility principle):-
A class should take care of only one responsibility.

O stands for OCP (Open closed principle):-
Extension should be preferred over modification.

L stands for LSP (Liskov substitution principle):-
A parent class object should be able to refer child objects
seamlessly during runtime polymorphism.

I stands for ISP (Interface segregation principle):-
Client should not be forced to use a interface if it does not need it.

D stands for DIP (Dependency inversion principle) :-
High level modules should not depend on low level modules
but should depend on abstraction.
