Homework Assignment Chapter 10b Create a new Java Project named Chap10b Create a class named Vehicle that acts as a superclass for vehicle types. The Vehicle class contains private data fields for the number of wheels and the average number of miles per gallon. The Vehicle class contains getters and setters for the data fields. The Vehicle class also contains a constructor receiving integer parameters for the number of wheels and average miles per gallons, and a display() method that prints the required output (use get methods). Create two subclasses, Car and MotorCycle, that each extend the Vehicle class. Each subclass contains a constructor that accepts the miles-per-gallon value as an argument and forces the number of wheels to the appropriate value-2 for a MotorCycle and 4 for a Car. Use the superclass constructor to set the wheels and mpg data fields (use the super keyword). Write a UseVehicle class to instantiate one object of each subclass and calls the display method to print…

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…
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…
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. *** I need help…
