Single Responsibility Principle
Open/Closed Principle
Liskov Substitution Principle
Interface Segregation Principle
Dependency Inversion Principle

Question 2

What is the Single Responsibility Principle?

Answer 2

A class should have only one responsibility.

Question 3

What is the Open/Closed Principle?

Answer 3

A class should be open for extension but closed for modification.

Question 4

What is the Liskov Substitution Principle?

Answer 4

Objects of a derived class should be able to substitute for objects of its base class.

Question 5

What is the Interface Segregation Principle?

Answer 5

Client code should not be forced to implement an interface or depend on methods it does not use.

Large interfaces should be split into multiple smaller ones.

Question 6

What is the Dependency Inversion Principle?

Answer 6

High-level and low-level concrete classes should not depend on each other directly. There should be abstraction between them. Classes should depend on abstract classes or interfaces.

Answer 7

The factory method design pattern abstracts the process of object creation and allows objects to be created at run-time.
