Write a complete program for the description given below. Consider a Billing class that implements an interface Payable having a method getTotalPayment Amount(). Besides this, you have a Doctor class with private instance variables (docID, docName, and docFee) and a public getDoc() method, Patient class with private instance variables (pName, pID. pDisease), Medicine class with private instance variables (medID, medName, medQty, medPrice), and Medical Test class with private instance variables (testID, testName, testPrice). Each of these classes has the toString() method to display the information of its object. The Billing class is having "Has A" relationship with the other four classes (Doctor, Patient, Medicine, and MedicalTest) mentioned above. The getPayment Amount() method of Billing class returns the total billing amount that includes doc fee, medicine cost, and medical test fee that a patient has to pay. After implementing these classes, you are required to do the following in…
Imagine you have two classes: Employee (which represents being an employee) and Ninja (which represents being a Ninja). An Employee has both state and behaviour; a Ninja has only behaviour. You need to represent an employee who is also a ninja (a common problem in the real world). By creating only one interface and only one class (NinjaEmployee), show how you can do this without having to copy method implementation code from either of the original classes.
Define a Polygon interface that has methods area() and perimeter(). Then implement classes for Triangle, Quadrilateral, Pentagon, Hexagon, and Octagon, which implement this interface, with the obvious meanings for the area() and perimeter() methods. Also implement classes, IsoscelesTriangle, Equilateral- Triangle, Rectangle, and Square, which have the appropriate inheritance relationships. Finally, write a simple user interface, which allows users to create polygons of the various types, input their geometric dimensions, and then out- put their area and perimeter. For extra effort, allow users to input polygons by specifying their vertex coordinates and be able to test if two such polygons are similar ORIGINAL WORKS ONLY
Write a java program Create an Abstract class Student that contains a method take exam, implement the method in the child classes PhdStudent and GradStudent in which PhdStudent takes exam by giving his final defense presentation while the graduate student gives a written paper.
Modify the GeometricObject class to implement the Comparable interface and define a static max method in the GeometricObject class for finding the larger of two GeometricObject objects. Draw the UML diagram and implement the new GeometricObject class. Write a test program that uses the max method to find the larger of two circles, the larger of two rectangles.using java programming
write program in java Design an abstract class GeometricObject. GeometricObject must ensure that its children must implement calcArea() method. Design RectangleYourRegNo and CircleYourName Classes as children of GeometricObject class with overridden toString() method to return “Rectangle with w Width and h Height is drawn” OR “Circle with r Radius is drawn”. The attributes of Rectangle are length, width. The attribute of Circle is radius Hint: Area of circle=πr2 , Area of rectangle= width*length
Make a Visible interface with the two methods makeVisible and makeInvisible. Both procedures must return a boolean value with no arguments. How would a class implement this interface?
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…

What is an abstract class? Choose only one option.(a) An object(b) A class with no methods.(c) A class with no concrete subclasses.(d) A class with at least one undefined message.(e) An interface.
Create an interface MessageDecoder that has a single abstract method decode(cipherText), where cipherText is the message to be decoded.The method will returnthe decoded message. Create a class SubstitutionCipher that implements the interface MessageDecoder as described above. The constructorshould have one parameter called shift. Define the method decode so that each letter is shifted by the value in the shif. For example, if shift is 3, a will be replaced by d, b will be replaced bt e, c will be replaced by f, and so on. Hint: You may wish to define a private methodthat shifts a single character. Create a class ShuffleCipher that implements the interface MessageDecoder. The constructor should haveone parameter called n. Define the method decode so that the message is shuffledn times.To perform one shuffle, split the message in half and then take the charactersfrom each half alternatively. For example, if the messsage is "abcdefghi", the halves are "abcde" and "fghi". The shuffled…
