Java Computer Programming. Each robot: - Has a name (attribute name: string) - Has a position: given by the integer attributes x and y. - Has a direction: given by the direction attribute that takes one of the values "North", "East", "South" or "West".

Using JAVA Language Consider a Billing class that implements an interface Payable having a method getTotalPaymentAmount(). 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 MedicalTest 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 getPaymentAmount() 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 the driver class: Create an ArrayList of…

After drawing the hierarchy, implement the classes by writing C# code foreach class. Then create objects of each class and call ALL methods onthese objects.

Write the constructor method for class Circle which is a subclass of Shape class. Class Shape has one attribute (color) and one constructor (with one parameter). Class circle has attribute for radius.

Create a UML class diagram of the application illustrating class hierarchy, collaboration, and the content of each class. There is only one class.  There is a main method that calls four methods.  I am not sure if I made the UML Class diagram correct. import java.util.Random; // import Random packageimport java.util.Scanner; // import Scanner Package public class SortArray{ // class name public static void main(String[] args) { //main method Scanner scanner = new Scanner(System.in); // creates object of the Scanner classint[] array = initializeArray(scanner); System.out.print("Array of randomly generated values: ");displayArray(array); // Prints unsorted array sortDescending(array); // sort the array in descending orderSystem.out.print("Values in desending order: ");displayArray(array); // prints the sorted array, should be in descending ordersortAscending(array); // sort the array in ascending orderSystem.out.print("Values in asending order: ");displayArray(array); // prints the…

Solve using OOP in Java.

Create a class Person to represent a person according to the following requirements: A person has two attributes: id   Add a constructer to initialize all the attributes to specific values. Add all setter and getter methods. Create a class Product to represent a product according to the following requirements: A product has four attributes: a reference number (can’t be changed) a price an owner (is a person) a shopName (is the same for all the products).   Add a constructer without parameters to initialize all the attributes to default values (0 for numbers, "" for a string and null for object). Add a second constructer to initialize all the attributes to specific values. Use the keyword "this". Add the method changePrice that change the price of a product. The method must display an error message if the given price is negative. Add a static method changeShopName to change the shop name. Add all the getter methods. The method getOwner must return an owner. Create the class…

Define an Animal method that updates the time to complete a particular behavior based on its name. Choose one of the following from the above choices (A, B, C or D within the code): public class Animal {       // Other instance variables, constructors and methods     // omitted for brevity       // A     public void updateTimeTakenForBehavior(String behaviorName, int timeToComplete) {         for(int i = 0; i < this.behaviorList.length; i++) {             Behavior tempBehavior = this.behaviorList[i];             if( tempBehavior.getBehaviorName().equals(behaviorName)) {                 tempBehavior.setTimeToComplete(timeToComplete);             }         }     }       // B     public void updateTimeTakenForBehavior(String behaviorName, int timeToComplete) {         for(int i = 0; i < this.behaviorList.length; i++) {             Behavior tempBehavior = this.behaviorList[i];             if( !tempBehavior.getBehaviorName().equals(behaviorName) ) {…
