1. Pet Class Write a class named Pet, which should have the following data attributes:
• _ _name (for the name of a pet)
• _ _animal_type (for the type of animal that a pet is. Example values are ‘Dog’, ‘Cat’, and ‘Bird’)
• _ _age (for the pet’s age) The Pet class should have an _ _init_ _ method that creates these attributes. It should also have the following methods:
• set_name This method assigns a value to the _ _name field.
• set_animal_type This method assigns a value to the _ _animal_type field.
• set_age This method assigns a value to the _ _age field. • get_name This method returns the value of the _ _ name field. • get_animal_type This method returns the value of the _ _animal_type field. • get_age This method returns the value of the _ _age field. Once you have written the class, write 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 as the object’s…

- Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.arrow_forwardObject composition is useful for creating a(n) _____relationship between two classes.arrow_forwardA class may have several constructors and it is called __________.arrow_forward
- Child Class: Vegetable Write a child class called Vegetable. A vegetable is described by a name, the number of grams of sugar (as a whole number), the number of grams of sodium (as a whole number), and whether or not the vegetable is a starch. Core Class Components For the Vegetable class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use instance data variables where appropriate a toString method that returns a text representation of a Vegetable object that includes all four characteristics of the vegetableJavaarrow_forwardEmployee class Write a Python program employee.py that computes the cumulative salary of employees based on the length of their contract and their annual merit rate. Your program must include a class Employee with the following requirements: Class attributes: name: the name of the employee position: the position of the employee start_salary: the starting salary of the employee annual_rate: the annual merit rate on the salary contract_years: the number of years of salary Class method: get_cumulative_salary(): calculates and returns the cumulative salary of an employee based on the number of contract years. Round the cumulative salary to two digits after the decimal point. Example: If start_salary = 100000, annual_rate = 5% and contract_years = 3: Then the cumulative salary should be : 100000 + 105000 + 110250 = 315250 Outside of the class Employee, the program should have two functions: Function name Function description Function input(s) Function output(s) / return…arrow_forward2. Car Class 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.

Each activity is identified by an activity code and includes other information such as description. Classes are offered for each activity. A class is uniquely identified by a combination of the activity code and the day/time at which it is held. It is assumed that a specific class will never be offered for the same activity at the same day and time, although it could be offered on a different day and/or time. Other information about a class includes the enrollment limit and the current enrollment count. A class will never include more than one activity. A passenger can sign up for a class as long as there is sufficient room in the class. Passengers are identified by a unique passenger number. Other information stored about passengers includes name, address, and age. Passengers have no limit on the number and type of classes they can sign up for.
