Chapter 6.2, Problem 6.8CP
You hear someone make the following comment: “A blueprint is a design for a house. A carpenter can use the blueprint to build the house. If the carpenter wishes, he or she can build several identical houses from the same blueprint.” Think of this as a metaphor for classes and objects. Does the blueprint represent a class, or does it represent an object?

What is the difference between a class and an object? Can you explain this using an example from the real world?
Write the missing code in the dark picture. This is not graded
In this activity, we are going to plan out and write a class definition that stores information for a book.
Let's say we want to store the following information about this book:
The book's name
The book's author(s) (a book can have more than one author)
The book's publisher
The book's ISBN number
The book's price
The book's year of publication
First, answer the following questions before the design:
1. What is a suitable name for this class? (Pick a name that best describes it).

Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1.

- For this assignment, you will be building a class, creating objects, doing comparisons and using nested control statements. You need to remember what you have learned in class, lab, books and your assignments. Be sure to refer to them when you need to. There are 2 parts to this assignment. In the first part, you are going to be given a problem and you will then need to create a structure, write algorithms and a flow chart to solve it. In the second part, you’ll be turning this into a java program. So let’s get started! Part 1: Your haunted house adventure: The user always starts the game at the front door and must immediately decide where they want to go. Your movement constraints are as follows: -From the front door, the user must choose between going into the living room, dining room or up the stairs. -To get from one room to the next, there must be a door. That means that to get to some rooms, the user must go through other rooms. See the above diagram for more details. -If the user…arrow_forwardYou are in charge of designing an enemy character of a video game using OOP. The video game is a side-scrolling arcade game, where the protagonist should evade numerous enemy characters. Assuming there are five different types of enemy characters and each is represented using a class, describe what methods and variables Mention at least three each. Also describe the purpose and motivation of each variable and method. Do not provide a code as an answer.arrow_forwardEvery employee in a firm XYZ has attributes employeeid, name and salary. However the sales employees in firm XYZ has all the attributes of employees and also has an additional attribute named bonus.

Write the constructors for both classes that set the attributes of both classes.arrow_forward
- You are designing a program that will keep track of the boxes in a doctor’s office. Each box will have three attributes: date, contents, and location. Write a class that will consist of box objects. Continuing with the program in problem #1, create instances of the class for these boxes: Box #23 contains medical records from 2016 and is in the storage closet. Box #21 contains lotion samples manufactured in 2018 and is in the waiting room. Box #07 contains flyers about the flu shot for 2020 and is in the receptionist’s desk. Continuing with the program in problem #2, write statements that will print out the date of box #23, the contents of box #07, and the location of box #21. Continuing with the program in problem #3, write a method that could be used to tell if the attributes of two boxes are identical. Continuing with the program in problem #4: Box #10 has identical attributes to Box #07. Create box #10.

Your need to create an instantiable class that represents a asteroid heading towards Earth. This class should be named Asteroid. It will contain three fields: a string named name and a mass and velocity, measured in kg and m/s respectively, each of which can accept numbers with decimal points. An observatory wants to know how much kinetic energy each asteroid will have as it passes or hits the earth. The class needs one constructor that sets the values of all the fields. The class needs the following public methods: Getters and setters for all fields. A method called getKineticEnergy that calculates and returns the kinetic energy of the asteroid.
