There are multiple geometric shapes available. (Language Java)

a. Your task is to organize the maximum number of shapes into appropriate level of inheritance. For example, all the squares are quadrilateral, and all the quadrilateral shapes are 2D shapes, and all the 2D shapes are shapes, just like that create a shape hierarchy.

b. Create a UML class diagram for all the shape hierarchy you created in step a. Your UML class diagram should represent all the structure of classes and the relationship between classes.

c. Explain the four basic OOP concepts in context of above shape hierarchy and highlight the advantage of using each of these OOP concept.
