SOLID OOP, Single Responsibility Principle

Single Responsibility Principle (SRP):

Single responsibility principle [1] means that any one class should not have more than one reason to change. For this to be true, a class will only have one single responsibility.

Avoid creating a god class [2]. Objects that are controlling way too many other objects in a system and often becoming “The Class That Does Everything” is known as a “God class”.

Straight forward easy to read comments on our classes and methods can help one recognize if the single responsibility principle is being adhered to.
