OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
To declare a class as abstract, you use the __________ in the class header.
a. abstract keyword
b. base keyword
c. void keyword
d. virtual keyword

- Write a class named Car that has the following member variables: Year: An int that holds the cars year model. Model: A string that holds the brand of the car. Speed: An int that holds the cars current speed. Color: A string that holds the color of the car. In addition, the class should have the following constructor and other member functions: Constructor: The constructor should accept the cars year, model ,speed and color as arguments. Accessor: Appropriate accessor functions to get the values stored in an object. Accelerate: The accelerate function should add 10 to the speed member variable If it’s value smaller than 50. Brake: The brake function should subtract 15 from the speed member variable If it’s value larger than 130. Count: The count function classifies the cars according to their model and their color. Afterward display the count of cars model= BMW and color=Red. Establish the class in a program that creates ten Car objects, and then calls the accelerate function ten…T/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.T/F: Instance variables are shared by all the instances of the class. T/F: The scope of instance and static variables is the entire class. They can be declared anywhere inside a class. T/F: To declare static variables, constants, and methods, use the static modifier.
- We use the _____ operator to create an instance of (object in) a particular class.The __________ declares that a derived class is allowed to override a method. a. void keyword b. protected keyword c. base keyword d. virtual keywordCar ClassWrite a class named Car that has the following fields:• yearModel. The yearModel field is an int that holds the car’s year model.• make. The make field references a String object that holds the make of the car.• speed. 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.• Constructor. The constructor should accept the car’s year model 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.• Accessors. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and speed fields.• accelerate.

- 2. 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. Then call the brake method five times. After…Course Title: Modern Programming Language Please Java Language Code Question : Create a class called with your 18Arid2891, as Invoice18Arid2891, that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables a part number (type String), a part description (type String),a quantity of the item being purchased (type int) and a price per item (double). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoice Amount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0. Write a test application named InvoiceTestMJibranAkram that demonstrates class Invoice’s…2.

- RetailItem Class Write a class named RetailItem that holds data about an item in a retail store. The class should have the following fields: description. The description field references a string object that holds a brief description of the item. • unitsonHand. The unitsOnHand field is an int variable that holds che number of units currently in inventory. price. The price field is a double that holds the item's retail price. Write a constructor that accepts arguments for each field, appropriate mutator methods that store values in these fields, and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three RetaillItem objects and stores the following data in them: Description Units on Hand Price Item #1 Jacket 12 59.95 Item #2 Designer Jeans 40 34.95 Irem #3 Shirt 20 24.951. Employee Class Write a class named Employee that has the following fields: • name. The name field references a String object that holds the employee's name. • idNumber.
