What You Must Implement:You must define a class named MediaRental that implements the MediaRentalInt interface functionality(index A). You must define classes that support the functionality specified by the interface. The followingspecifications are associated with the project:1. Define a class named MediaRental. Feel free to add any instance variables you understand are needed or anyprivate methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).2. The media rental system keeps track of customers and media (movies ,music albums and games). A customerhas a name, address as string , a plan and two lists. One list represent the media the customer is interested inreceiving and the…Is there a different way of doing this problem? Question: Create a class AccessPoint with the following attributes: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Also, add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overlap that checks if two access points overlap their coverage and returns true if they overlap. Add a function signalStrength that returns the wireless signal strength as a percentage. The signal strength decreases as one moves away from the access point location. Test your class by writing a main function that creates five access…
- In Java. Screenshot explains. Implement the Shape hierarchy -- create an abstract class called Shape, which will be the parent class to TwoDimensionalShape and ThreeDimensionalShape. The classes Circle, Square, and Triangle should inherit from TwoDimensionalShape, while Sphere, Cube, and Tetrahedron should inherit from ThreeDimensionalShape.Each TwoDimensionalShape should have the methods getArea() and getPerimeter(), which calculate the area and perimeter of the shape, respectively. Every ThreeDimensionalShape should have the methods getArea() and getVolume(), which respectively calculate the surface area and volume of the shape. Every class should have a member variable containing its dimensions -- for example, the Circle class should have a member variable describing its radius, while the Triangle class should have three member variables describing the length of each side. Note that the Tetrahedron cass should describe a regular tetrahedron, and as such, should only have one member…Create the class Student, which must have a normalconstructor and at least 5 attributes Attributes ; ID, name, Semester Gender, Age JAVAImplement the Shape hierarchy -- create an abstract class called Shape, which will be the parent class to TwoDimensionalShape and ThreeDimensionalShape.

- Create a Cycle class, with subclasses Unicycle, Bicycle and Tricycle. Demonstrate that an instance of each type can be upcast to Cycle via a ride( ) method. Using the above Cycle hierarchy, add a balance( ) method to Unicycle and Bicycle, but not to Tricycle. Create instances of all three types and upcast them to an array of Cycle. Try to call balance( ) on each element of the array and observe the results. Downcast and call balance( ) and observe what happens.Add the following constructor to your Rectangle class: public Rectangle(Point p, int width, int height) Construct a new Rectangle whose top-left corner is specified by the given Point and with the given width and height.We already have the address and vehicle class for the system below. We will need a CarShow class with IsSanctioned() method, Owner class with IsOwner method and a main class that creates objects and implements all our existing classes. Use the class diagrams. Make sure to include respective attributes, setters, getters and constructors in your code Explain your code in a few words.
