Write a code for the following using Console.WriteLine. Class Exercise:• Create an interface called I Temp with aconstructor named convert Temp()• Create an implement class named Fahrenheitto implement the interface. The constructor ofthe class converts a 100 degrees Fahrenheit intocentigrade using the formula:cles = 5.0/9.0 * (fah - 32.0);and displays the message: "100 degrees in Fahrenheitequal 37.78 Celsius."

Start with this class declaration: class Student { int sId; String name; double gpa;} Implement a Comparable and Comparator interface to provide the following three (3) alternative ways of ordering for the Student objects - based on sId (i.e., assume that this is selected as the natural ordering)- based on name, - based on gpa. Next declare a list of five Student objects, initialize them with random values. Test your code by printing out each of the following on separate lines: (original list of students, sorted list of students in ascending sId order, sorted list of students in ascending name order, sorted list of students in ascending gpa order).
Java Exercise 3. Movable PointA. Write the classes as shown in the following class diagram. Movable is an interface and MovablePoint implements it. ‘~’ means package access but you can just make it public. (pic1.png) B. Now add the class MovableCircle which also implements the interface Movable and is composed of a MovablePoint. Add a tester that allows the user to enter the radius and center of a MovableCircle. After that ask the user if they want (yes/no) to move the circle and how they want to move it (up, down, left, right). Everytime the circle is moved, you should output its changed position. If the user says “no” the program ends. (pic2.png)
Description: Create a class named ComparableDog that extends Animal and implements Comparable interface. Implement the compareTo method to compare the Dogs on the basis of age. Write a test class to find the bigger age of two instances of ComparableDog Objects, and complement the ComparableDog class with the missing part. 1) The test program, the ComparableDog class, and its super class Animal are given as follows. // Main method public static void main(String[] args) { // Create two comparable Dogs ComparableDog dog1 = new ComparableDog(3); ComparableDog dog2 = new ComparableDog(4); System.out.println("Dog1:" + dog1); System.out.println("Dog2:" + dog2); if(dog1.compareTo(dog2) == 1) System.out.println("Dog1 is older than Dog2"); else if(dog1.compareTo(dog2) == -1) System.out.println("Dog1 is younger than Dog2"); else System.out.println("Dog1 and Dog2 have the same age"); }…
Java program * Interfaces 1. Modify the class Rectangle to implement the Comparable interface, as shown in the following UML class diagrams. Apply the required changes in the class’s header.2. Then, in the Rectangle class override the method compareTo(), so if this object’s area is greater than the specified (given through the parameter) object’s area return 1, if it is less than return -1, and 0 otherwise. 3. Create a test class named Test2. Then complete the following tasks: a. Create an ArrayList and add to it 4 Rectangle objects with different width and height values. b. Print out the elements of the ArrayList. c. Sort the elements of the ArrayList using the static method sort of the class java.long.Collections. This would be possible only, if you implemented the method compareTo() correctly in the Rectangle class. d. After sorting the elements of the ArrayList, print the elements again. 4. Run the Test class. Here is the rectangle's class program public class Rectangle extends…
JAVA PROGRAM Create a class EmployeeImp and do the following implement interface EmployeeInterface Define the following attributes: int count and an array variable of type Employee. Write a default constructor and initialize array Employee with the size defined in EmployeeInterface Write a constructor that accepts size of an array as parameter. Create array Employee with the parameter size. Use the attached photo of diagram below as reference for the data members of each class. Note: No need to define interface EmployeeInterface, Employee, HourlyEmployee and CommisionEmployee
1.Use inheritance and classes to represent a deck playing cards. Create a Card class that stores the suit (e.g., Clubs, Diamonds, Hearts, Spades) and name (e.g., Ace, 2, 10, Jack) of each card along with appropriate accessors, constructors, and mutators.2.Next, create a Deck class that stores an ArrayList of Card objects. The default constructor should create objects that represent the standard 52 cards and store them in the ArrayList. The Deck class should have methods to do the following: Print every card in the deck. Shuffle the cards in the deck. You can implement this by randomly swappingevery card in the deck. Add a new card to the deck. This method should take a Card object as a parameter and add it to the ArrayList. Remove a card from the deck. This removes the first card stored in the ArrayList and returns it. Sort the cards in the deck ordered by name. 3.Next, create a Hand class that represents the cards in a hand. Hand should be derived from Deck. This is…

T/F1. Interface classes cannot be extended but classes that implement interfaces can be extended.
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 arrav 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 retums 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.
JAVA OOP 2 Design a currency converter class whose instance will handle conversion of all currencies. A single instance of the new currency converter class you design here will handle all currencies. Instead of having specific conversion methods such as toDollar, toYen, and so forth, the new currency converter class supports one generic conversion method called exchange. The method has three arguments: fromCurrency, toCurrency, and amount. The first two arguments are String and give the names of currencies. The third argument is float.
Define an interface as follows: Interface Bicycle { // wheel revolutions per minute void changeCadence(int newValue); //will change value of candence to new value void changeGear (int newValue); changes gear of car void speedUp(int increment); //increments speed of car by adding new Value to existing speed void applyBrakes(int decrement); }//decease car speed by subtracting value from speed. To implement this interface, the name of your class would change (to a particular brand of bicycle, for example, such as ACMEBicycle, KEYOBicycle), and you'd use the implements keyword in the class declaration: class ACMEBicycle implements Bicycle{ int cadence = 0; int speed = 0; int gear = 1; //methods of interface } These clases will implements the abstract method of interface and provide definitions according to them. Now in main class you will ask user what kind of bicycle he/she wants create object of that class, then asks user for options 1. Change cadence 2. Change gear 3. Speed…
