S.O.L.I.D. Class Design Principles

Abbreviation Full Form Definition Reason S Single Responsibility Principle A class should have only one reason to change i.e. should have only one purpose to serve.  - loosely coupled - less change lead to less break down of application - helps to change identity of object without affecting other modules O Open-Closed Principle A class should be open for extension closed for modification. - Anyone need to make change in your class has to inherit the class and change. This allows the existing functionality to stay intact. L Liskov Substitution Principle Derived types should always be substitutable by its parent class (base type). Derived types should be compatible with its base type. For e.g.: Square is a Rectangle i.e. Square represents a Rectangle. In case, if we try to set dimension of a Rectangle reference pointing to Square instance, the flow will be weird as it will always override the dimension of rectangle. I Interface Seg...

Hunt of Self Interest

I started painting last year in month of August after which I found it really interesting. The below painting is the one I did as a beginner. It was loved by my best buddy Sanjivanee and so I felt to present her this painting as token of thanks. @Sanj: Thanks for encouraging me  :)

Open-Closed Principle

'A class should be open for extension closed for modification.' The above principle explains that a class once defined should not be changed(closed for modification). This is because it may impact other parts of application. Hence, if modification is needed, that class behaviour should be extended and modification should be done. (open for extension) Consider a scenario where area of a shape(like rectangle, square, circle) is calculated within Main class. Now addition of any new shape will lead to change in Main class. This concludes that the Shape is tightly coupled with Main class. In order to avoid this Shape should be inherited by diff Shape classes like Rect, Triangle, Circle implementing the behaviour of calculating area() and Main class should be loosely coupled by using Shape.area() (as Triangle, Rectangle are Shape). Hence, Shape interface is contract between its concrete classes and Main class. This allows us to add new shape class without any impact on exi...
