non-abstract subclasses: one encapsulating a bicycle, and the other encapsu-lating a motorized vehicle. A motorized vehicle has the following additionalattributes: its engine volume displacement, in liters; and a method computingand returning a measure of horsepower-the number of liters times the num-ber of wheels. You also need to include a client class to test these two classes. 49. Write an abstract superclass encapsulating a vehicle: A vehicle has twoattributes: its owner's name and its number of wheels.

2. Implement the class below such that it should provide structure with necessary Data Members to all the sub-classes of itself. The object creation of this class is not mandatory. Book -name:String -author:Author -price:double -qty:int = 0
An instance of an abstract class is made by using the keyword 'new'. true or false
Design a new Triangle class that extends the abstract GeometricObject class: Draw the UML diagram for the classes Triangle and GeometricObject Implement the Triangle class Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled: The program should create a Triangle object with these sides and set the color and filled properties using the input The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not
Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
Create abstract class Pet , which is the abstract superclass of all animals. Declare a integer attribute called legs, which records the number of legs for this animal. Define a constructor that initializes the legs attribute. Declare an abstract method eat. Declare a concrete method walk that prints out something about how the animals walks (include the number of legs). Create the Dog class. The Dog class extends the Pet class. This class must include a String attribute to store the name and food of the pet Define a default constructor that calls the superclass constructor to specify that all dogs have 4 legs and name. override the eat and walk method. Create the Cat class that extends Pet. This class must include a String attribute to store the name of the pet, and a string to save food . Define a constructor that takes one String parameter that specifies the cat's name and food. This constructor must also call the superclass constructor to specify that all cats have four legs.…

JAVA CODE Write a java set of classes that could be used to do simple calculations on geometricobjects. The set should include the following classes: a) Shapes ,containing abstract methods( a methods that is declared without animplementation) area and perimeter b) Rectangle, a subclass of Shape, containing a constructor (with parameters forlength and width) along with methods area and perimeter. c) Triangle, a subclass of Shape, containing a constructor (with parameters for the three sides of a triangle) along with methods area ( s = (a+b+c)/2, A = sqrt( s(s-a)(s-b)(s-c) ) ) and perimeter d) Square, a subclass of Rectangle, containing a constructor (with a parameter for thelength of a side) and methods that invoke the methods of the Rectangle class todetermine the perimeter and area of a square.

1). Write a java abstract class called Solid and you will derive two classes – Cylinder and Sphere – from Solid. The class Solid Member variables type whose data type is String. For example, the type could be sphere, cube, parallelepiped. 2). The methods should include: A default or null constructor A constructor that initializes the value of type Getters and Setters An abstract method to find volume whose signature is public abstract double findVolume(); An abstract method to find surface area whose signature is public abstract double findSurfaceArea() a toString method that returns a string like the following Solid Type: Sphere an equals method that returns true if two Solid objects have the same type and false otherwise. 3). The class Cylinder - Cylinder will extend Solid Member variables: Cylinder inherits type from Solid radius of type double height of type double Methods: a default or null constructor a constructor that initializes type, radius, and height. type will always…
