PROBLEM: 1. Write a Rectangle class in Python language, allowing you to build a rectangle with length and width attributes. 2. Create a Perimeter() method to calculate the perimeter of the rectangle and a Area() method to calculate the area of the rectangle. 3. Create a method display() that display the length, width, perimeter and area of an object created using an instantiation on rectangle class. 4. Create a Parallelepipede child class inheriting from the Rectangle class and with a height attribute and another Volume() method to calculate the volume of the Parallelepiped.

The Factory method design pattern is advantageous since it enables dynamically creating new objects of a certain kind. True Untrue

Design a class in python named Book that holds a stock number, author, title, price, and number of pages. Include methods to set and get the values for each data field. Also include a displayInfo() method that displays each of the Book's data fields with explanations.Design a class named TextBook that is a child class of Book. Include a new data field for the grade level of the book. Override the Book class displayInfo() method to accommodate the new grade-level field.

Design a class named CustomerRecord that holds a customer number, name, and address. Include separate methods to 'set' the value for each data field using the parameter being passed. Include separate methods to 'get' the value for each data field, i.e. "return" the field's value. Pseudocode:

Create an interface named as “TeaService” having following method abstract methods Boling Tea Serving Tea Is Tea Hot Create another interface named as “BiscuitService” having following method abstract methods Bake Biscuit Serving Biscuit Is Biscuit Baked Create another interface named as “TeaParty” having only one default method but inherit both interfaces: “TeaService” and “BiscuitService”. Default method name is “partyStarted” and displays “Party is started”. Create a class named “SchoolTeaParty” having two boolean attributes: bakedBiscuit and hotTea. Complete the class such that for the following main method it produces output as show below. Main Class with main method public class Main {                 public static void main(String[] args) {                                 SchoolTeaParty schoolTeaParty = new SchoolTeaParty();                                 schoolTeaParty.serveBiscuit();                                 schoolTeaParty.servingTea();…

Which advantages do interfaces provide? Is it not more convenient to construct objects that belong to a certain class?

Java program: 1. Create a class named Rectangle that has instance variables height and width. Provide a constructor that initializes the instance variables based on parameter values, getter and setter methods for the instance variables, a toString method, and a method named computeSurfaceArea(), that returns the surface area of the rectangle. 2. Create a child class named RectPrism that contains an additional instance variable named depth. Provide a constructor, getter and setter methods for the new instance variable, and a method named computeVolume(), that returns the volume of the rectangular prism. Override the toString() and the computeSurfaceArea() methods. 3. Write an application called Demo, that instantiates a rectangle and a rectangular prism, and tests all the methods. Make sure you indent and comment your code based on the examples in the textbook. Don’t forget to include your name, the course number, title of the assignment, and today’s date.
