Car Class
Create a class named Car that has the following properties:
- Year—The Year property holds the car’s year model.
- Make—The Make property holds the make of the car.
- Speed—The Speed property holds the car’s current speed.
In addition, the class should have the following constructor and other methods:
- Constructor—The constructor should accept the car’s year and model and make them as arguments. These values should be assigned to the backing fields for the object’s Year and Make properties. The constructor should also assign 0 to the backing field for the Speed property.
- Accelerate—The Accelerate method should add 5 to the Speed property’s backing field each time it is called.
- Brake—The Brake method should subtract 5 from the Speed property’s backing field each time it is called.
Demonstrate the class in an application that creates a Car object. The application’s form should have an Accelerate button that calls the Accelerate method and then displays the car’s current speed each time it is clicked. The application’s form should also have a Brake button that calls the Brake method and then displays the car’s current speed each time it is clicked.

- 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. The output Should be…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_forwardMonth 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. If an invalid name is passed, the constructor should throw an InvalidMonthNameException. A setMonthNumber method that accepts an int argument, which is assigned to the monthNumber field. If a value less than 1 or greater than 12 is passed, throw an…arrow_forward
- java Assignment Description: Write a class named Car that has the following fields: The yearModel field is an int that holds the car’s year model. The make field references a String object that holds the make of the car. The speed field is an int that holds the car’s current speed. In addition, the class should have the following constructor and other methods. The constructor should accept the car’s year and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field. Constructor: The constructor should accept no arguments. Constructor: The constructor should accept the car’s year as argument.Assign the value to the object’s yearModel. No need to assign anything to the make and assign 0 to speed. Appropriate mutator methods should set the values in an object’s yearModel, make, and speed fields. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and…arrow_forwardCreate a class named Car that has the following properties: • Year—The Year property holds the car’s year model. • Make—The Make property holds the make of the car. • Speed—The Speed property holds the car’s current speed.

- 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_forwardTrue or False The get accessor can be thought of as a method that returns the class property’s value.arrow_forwardEmployee and ProductionWorker Classes Create an Employee class that has properties for the following data: Employee name Employee number Next, create a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have properties to hold the following data: Shift number (an integer, such as 1, 2, or 3) Hourly pay rate The workday is divided into two shifts: day and night. The Shift property will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Create an application that creates an object of the ProductionWorker class and lets the user enter data for each of the object’s properties. Retrieve the object’s properties and display their values.arrow_forward
