Assume you have a system with the followoing entities Region ID, Len, Width int Area ()//zero City Country T. ID, Len, Width Area () ID, Len, Width city *A//array of cities Area () 1. Implement the above system using inheritance in the best possible way. Keep every object size as small as possible. Implement all methods (setter/getter/constructors and destructors) Note that the region area is 0 while the city is len"width and the country is the sum of their cities. 2. Create array of countries called Arab of 22 countries. Write a function fill that fills the array Arab 3. Write a method that finds the city that has the max area in a country 4. Write a method that sorts the cities in a country from the largest to the smallest area 5. Write a function that returns array of countries of the same area of Arab 6. Write a function that compares between two countries. It returns true if countryl area greater than country2 area. 7. Write a function to move a city from one country to another.

You have to implement program that compares graduate students based on their ranks. The design of the program is given in the following UML diagram: • Student class: Base class that GradStudent extends. • GradStudent class: The objects from this class will be used for comparisons. • Rankable interface: Defines the implementation needed for comparison. GradStudent implements this interface. • Test class will be used to get student information from the user and demonstrate the comparison of students.
Using JAVA: Implement the following class diagram which is based on the program of study. You can refer the ProgramOfStudy implementation as reference:
accessor methods for each of the instance variables A local taxi company has decided to expand and not only have taxis that go on land (i.e., cars), but also taxis that go on water (i.e., boats). You have been asked to design a number of classes to represent the various taxi fares (trips with passengers) and their various fee structures, by using inheritance in Python. a computeCharges method that returns the total charges for the cab fare, using the instance variables and the defined constants (i.e., kms multiplied by the cost per km, plus minutes multiplied by the cost per minute) Please read all parts of this question below before starting the question. Include the completed code for all parts of this question in a file called taxi_company.py- NOTE: To implement encapsulation, all of the instance variables/fields should be considered private. Question 3 (a) Design and implement a class called TaxiFare that includes the following instance variable(s) and method(s) for an object.…
Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram { public static void main (String [] args) { Course course = new Course(); // Example students for testing course.addStudent(new Student("Henry", "Bendel", 3.6)); course.addStudent(new Student("Johnny", "Min", 2.9)); System.out.println("Course size: " + course.courseSize()); } } public class Student { private String first; // first name private String last; // last name private…
USING JAVA: Part A) Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An Appointment has a description (for example, “See the dentist”) and a date. Write a method, occuresOn(int year, int month, int day) The check whether the appointment occurs on that date. For example, for appointment, you must check whether the day of the month matches. This fill an array of Appointment objects with a mixture of appointments. Have the user enter a date and print out all appointments that occur on that date. Part B) Improve the appointment book by giving the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.
B elow for each class you find a UML and description of the public interface. Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked. It's important to implement the drivers to test and demonstrate…
Create a Java Project (with a class and a test class) to represent some real-world entity such as a technology item (TV, Fan etc), an animal, a person, a vehicle, etc. In seen example classes such as Circle, Student, Rectangle, TV etc. class, we have already The class will: a) Create a total of 5 member variables for the class by selecting the appropriate data types for each field. For example, a class to represent a lamp might include color, price, height, numBulbs, batteryOperated. Each of these 5 variables needs a data type. b) Include at least three different constructor methods, including the default constructor (no argument constructor), so totally three constructors. c) Create a method called showValues( ) to display the values of an object in a formatted manner. The Java test class (with a main method) will: a) Instantiate at least three objects (using each of the constructors at least once) with your program. b) Store the data from the individual objects into an array. c)…

Part 1: Abstract Classes 1. Copy the source files of Circle, Rectangle and GeometricObject classes (located in LabFiles folder) and paste them in the default package (You may need to fix any problems related to package declaration). 2. Open Circle, Rectangle and GeometricObject classes using NetBeans editor and go through the classes’ implementation. 3. In the GeometricObject class add two methods called respectively getArea() and getPerimeter(). Discuss: 1. Is the area formula of a circle similar to area formula of a rectangle? Since: GeometricObject is the superclass of Circle and Rectangle, and getArea() method is a common method in both Circle and Rectangle classes. Then: 2. Should you define the getArea() method in the superclass GeometricObject? Or in the subclasses Circle and Rectangle? 3. If yes, Should the getArea() method be declared as abstract method in the superclass GeometricObject? Or as instant method? 4. Is declaring getArea() as abstract, would solve…

You need to perform following things to demonstrate the concept of abstract class. Step 1: Create the abstract class that has following methods. • Calculate the area of circle(Abstract method) • Calculate the area of triangle(Abstract method) • Calculate the area of rectangle(Method with implementation) Step 2: Create another class that extends above class and provide implementation of abstract methods. Step 3: Create the main method inside above class and display output of area of circle, area of triangle and area of rectangle.
