- 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 programmingModify the GeometricObject classto implement the Comparable interface and define a static max method in theGeometricObject class for finding the larger of two GeometricObject objects.Draw the UML diagram and implement the new GeometricObject class. Writea test program that uses the max method to find the larger of two circles, the largerof two rectangles.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?
- 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.For a parking management system, use the Observer pattern to implement this interaction using Java and implement the three classes mentioned below. Implement a ParkingObserver that has the role of the Observer. The Observable classes (Subjects) will be the ParkingLots. It would be helpful if the notify method in the subjects (and update method in the observers) took a parameter, perhaps an object of type ParkingEvent, which could have fields including the lot, timeIn, timeOut (if relevant), and permit. The ParkingObserver should register with each ParkingLot and receive the messages. Once a car enters (in an entry-scan only lot) or leaves (in an entry-scan and exit-scan lot), then the ParkingObserver will be updated, and then can register the charge with the parking system via the TransactionManager’s park() method. Based on these requirements you should implement three actor classes in this interaction using java: TransactionManager, ParkingObserver and ParkingLot. 1. The…Implement a new class that implements Comparatorof GregorianCalendar class to be able sort the calendar in increasingorder based on day, month, and year, in that order. Write a method to displaythe GregorianCalendar instance in “dd-MMM-yyyy” format usingSimpleDateFormatclass. Write a test program with 10 GregorianCalendarinstances and display the results after the sort.
- 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.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…Implement a class Moth that models a moth flying along a straight line. The moth has a position, which is the distance from a fixed origin. When the moth moves toward a point of light, its new position is halfway between its old position and the position of the light source. Supply a constructor Public Moth(double initialPosition) and methods pubc void moveToLight(double 1ightPosition) public double getpsition() Your MothTester should construct a moth, move it toward a couple of light sources, and check that the moth's position is as expected.
- Consider the following code. Replace the tags _??1_ and _??2_, respectively, by filling in the text fields below, such that the interface myInterface inherits from interfaces A and B and declares an (abstract) interface method trim with one String argument returning an int. interface A {public static final int x = 10;}interface B {public static int foo(int x){ return x+1; }}interface myInterface extends A _??1_ B { // replace _??1_ public int _??2_ (String s); // replace _??2_ } _??1_:Question Blank 1 of 2._??2_:Question Blank 2 of 2.Implement a toString method for the following class that returns a string containing the class name and the names and values of all instance variables.Implement using Java Create an interface that shall have 2 methods and one string type attribute, also create an implementation class of the interface that shall define both methods (you can print YOUR favorite quote in each method body).
