Write a class definition for the class called Bookshelf described below: • Private member variables: • shelves: an integer representing the number of shelves on the bookcase. shelfHeight: a double representing the height of each individual shelf in inches. All shelves share the same height. • Member methods: • A constructor which has 2 arguments, one each to set the initial values of the two member variables. Neither of these arguments is allowed to be 0 or less: . If the number of shelves is entered as O or less, set it to 6 inside of the constructor instead. . If the height of each shelf is entered as O or less, set it to 12 inside of the constructor instead. o getBookshelf Height: a method which returns the total height of the bookshelf in feet (as a double). The height of the bookshelf can be obtained by multiplying the height of each shelf by the number of shelves, then dividing by 12 (to convert from inches to feet)

OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Question

Java

Write a class definition for the class called Bookshelf described below:
• Private member variables:
• shelves: an integer representing the number of shelves on the bookcase.
• shelfHeight: a double representing the height of each individual shelf in
inches. All shelves share the same height.
• Member methods:
• A constructor which has 2 arguments, one each to set the initial values of the
two member variables. Neither of these arguments is allowed to be 0 or less:
▪ If the number of shelves is entered as O or less, set it to 6 inside of the
constructor instead.
O
■ If the height of each shelf is entered as O or less, set it to 12 inside of the
constructor instead.
getBookshelfHeight: a method which returns the total height of the
bookshelf in feet (as a double). The height of the bookshelf can be obtained
by multiplying the height of each shelf by the number of shelves, then
dividing by 12 (to convert from inches to feet)

Pyhton Code: Create a Pizza class which stores information about a single pizza. It contains the following: -Instance variables to store the size of the pizza (small, medium or large), (1)the number of cheese toppings, (2)the number of pepperoni toppings, and the (3) number of mushroom toppings. - Constructor: that takes four arguments and sets all of the corresponding instance variables and that initializes all instance variables to the zero of their type. - Methods to get (accessor) and set (mutator) each instance variable individually. - A method called calcCost() that returns the cost of the pizza.
