Pet ClassDesign a class named Pet, which should have the following fields:
name: The name field holds the name of a pet.
type: The type field holds the type of animal that a pet is. Example values are "Dog", "Cat", and "Bird".
age: The age field holds the pet’s age.
The Pet class should also have the following methods:
setName: The setName method stores a value in the name
setType: The setType method stores a value in the type
setAge: The setAge method stores a value in the age
getName: The getName method returns the value of the name
getType: The getType method returns the value of the type
getAge: The getAge method returns the value of the age
Once you have designed the class, design a program that creates an object of the class and prompts the user to enter the name, type, and age of his or her pet. This data should be stored in the object. Use the object’s accessor methods to retrieve the pet’s name, type, and age and display this data on the screen.

- Month Class Exceptions Write a class named Month. The class should have an int field named monthNumber that holds the number of the month. For example, Janauary would be 1, February would be 2, and so forth. In addition, provide the following methods: A no-arg constructor that sets the monthNumber field to 1. A constructor that accepts the number of the month as an argument. It should set the monthNumber value to the value passed as the argument. If a value less than 1 or greater than 12 is passed, the constructor should throw an InvalidMonthNumberException. A constructor that accepts the name of the month, such as “January” or “February”, as an argument. It should set the monthNumber field to the correct corresponding value.

- Focus on classes, objects, methods and good programming style Your task is to create a BankAccount class. Class name BankAccount Attributes _balance float _pin integer Methods init () get_pin() check pin () deposit () withdraw () get_balance () The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0. get_pin () should return the pin. check_pin (pin) should check the argument against the saved pin and return True if it matches, False if it does not. deposit (amount) should receive the amount as the argument, add the amount to the account and return the new balance. withraw (amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was not. get_balance () should return the current balance.…arrow_forwardC# Console Application for Minesweeper In this milestone, students will create three classes: Cell, Board, and Program. Create a class that models a game cell. A game cell should have the following properties: a.Its row and column. These should initially be set to -1. b.Its visited boolean value. This should initially be set to false. c.Live boolean value. This should initially be set to false. "Live" set to true will indicate that the cell is a "live bomb" cell. d.The number of neighbors that are "live." This should initially be set to 0. The Cell class should have a constructor, as well as getters and setters for all properties. 3.Create a class that models a game board. A game board should have the following properties: a.Size. The board will be square, where the size includes the dimensions of both the length and width of the board. b.Grid. The grid will be a 2-dimensional array of the type cell. c.Difficulty. A percentage of cells that will be set to "live" status. 4.The Board…arrow_forwardINVENTORY CLASS You need to create an Inventory class containing the private data fields, as well as the methods for the Inventory class (object). Be sure your Inventory class defines the private data fields, at least one constructor, accessor and mutator methods, method overloading (to handle the data coming into the Inventory class as either a String and/or int/float), as well as all of the methods (methods to calculate) to manipulate the Inventory class (object). The data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…arrow_forward
- A. Car Class Create a Python Program where you write a class named Car that has the following data attributes: • _ _year_model (for the car's year model) • __make (for the make of the car) • _ _speed (for the car's current speed) The Car class should have an _init_ method that accepts the car's year model and make as arguments. These values should be assigned to the object's _year_model and make data attributes. It should also assign 0 to the __speed data attribute. The class should also have the following methods: accelerate() The accelerate method should add 5 to the speed data attribute each time it is called. brake() The brake method should subtract 5 from the speed data attribute each time it is called. • get_speed() The get_speed method should return the current speed. Next, design a program that creates a Car object then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method…arrow_forwardT/F A method defined in a class can access the class' instance data without needing to pass them as parameters or declare them as local variables.arrow_forwardDynamic Games Instructions: Write a class called Game that contains a video game’s name, genre, and difficultyLevel. Include a default constructor and destructor for the class. The constructor should print out the following message: “Creating a new game”. The destructor should print out the following message: “In the Game destructor.” Include appropriate get/set functions for the class. In main(), prompt the user to enter the number of games he or she has played in the past year. Dynamically create a built-in array based on this number (not a vector or object of the array class) to hold pointers to Game objects. Construct a loop in main() that executes once for each of the number of games that the user indicated. Within this loop, ask the user to enter the name and genre of each game. Using a random number generator, generate a difficultyLevel between 1-10 (inclusive). Seed this random number generator with 100. Next, dynamically create a Game object (remember that this…arrow_forward
- 2. Car Class Write a class named car that has the following fields: ▪ yearModel. The year Model field is an int that holds the car's year model. ▪ make. The make field is a String object that holds the make of the car, such as "Ford", "Chevrolet", "Honda", etc. ▪ speed. The speed field is an int that holds the car's current speed. In addition, the class should have the following methods. ■ Constructor. The constructor should accept the car's year model and make as arguments. These values should be assigned to the object's year Model and make fields. The constructor should also assign 0 to the speed field.arrow_forwardC++ Stars This lab exercise will practice creating objects with constructors and destructors and demonstrate when constructors and destructors are called. Star Class Create a class, Star. A Star object has two member variables: its name, and a solar radius. This class should have a constructor which takes a std::string, the name of the star, and a double, the solar radius of the star. In the constructor, the Star class should print to the terminal that the star was born. For example, if you create a Star as follows: Star my_star("Saiph", 22.2); Then the constructor should print: The star Saiph was born. In the destructor, the Star class should print to the terminal that the star was destroyed, along with the number of times the volume of the sun that that star was, formatted to two decimal places. Hint: use the following line to set the precision to 2 decimal places: std::cout << std::fixed << std::setprecision(2); For example, when my_star above has its destructor called,…arrow_forwardLab 2 – Designing a class This lab requires you to think about the steps that take place in a program by writing pseudocode.
