Develop the ‘Shape’ application such that: ‘Rectangle’, ‘Ellipse’, and ‘Triangle’ classes inherit from the ‘Shape’ class. Develop the ‘Square’ and ‘Circle’ class where ‘Square’ inherits from ‘Rectangle’ and‘Circle’ inherits from ‘Ellipse’. ‘Triangle’ has no derived class. For each class, implement the overridden methods ‘draw’, ‘move’, and ‘erase’. Eachmethod should only have an output statement such as “Rectangle – draw method”that will be displayed when the method is invoked. Implement the default constructors for each class with a corresponding message tobe displayed when invoked. No initializations are required; that is, the outputmessage will be the only executable statement in the constructors. Do not implement any other methods for these classes ( i.e., ‘toString’, ‘equals’,getters and setters ). Implement a ‘ShapeTest’ class which will instantiate an object of each class. Exercise each of the ‘draw’, ‘move’, and ‘erase’ methods of each class Remember to make sure that…

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.
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…
Override the testOverriding() method in the Triangle class. Make it print “This is theoverridden testOverriding() method”. (add it to triangle class don't make a new code based on testOverriding in SimpleGeometricObject class.) (this was the step before this one) Add a void testOverriding() method to the SimpleGeometricObject class. Make it print“This is the testOverriding() method of the SimpleGeometricObject class”
Part 1: Setting the turtle size when it is instantiated Currently, a turtle is created and given a default size of 50. To change the size of the turtle its increaseTurtleSizeBy10 and decreaseTurtleSizeBy10 methods can be called. Add functionality so that a turtle can be created with a specified size. In the DoodleTurtle class do the following: Overload the DoodleTurtle constructor by creating a one-parameter constructor that takes the size of the turtle as an integer. Add an empty method body. Complete the method specification for the new constructor. The default constructor method specification can be used as a model. The only difference will be that the getTurtleSize() will equal the name of the size parameter instead of INITIAL_SIZE. In the method body of the one-parameter constructor do the following in this order: Call the initializeWithDefaultValues helper method. Call the setSize method passing it the size parameter. Compile the program and fix any…
Why is it important for a class to have a destructor implemented? With your comment, fill in the spaces.
Fibonacci A fibonacci sequence is a series of numbers in which each number is the sum of the two preceding numbers. For example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on… For this, you will implement a class that takes a positive integer (n) and returns the number in the nth position in the sequence. Examples When n is 1, the returned value will be 0. When n is 4, the returned value will be 2. When n is 9, the returned value will be 21. come up with the formula and base cases Implementation Create a class Fibonacci with a public static method getValue. Create a Main class to test and run your Fibonacci class.
In the board game Scrabble, each tile contains a letter, which is used to spell words in rows and columns, and a score, which is used to determine the value of words. The point of this exercise is to practice the mechanical part of creating a new class definition: Write a definition for a class named Tile that represents Scrabble tiles. The instance variables should be a character named "letter" and an integer named "value". Write a constructor that takes parameters named letter and value, and initializes the instance variables. Create getters for both of the attributes. (No setters, so that a Tile is immutable.) Implement the .toString() and .equals methods for a Tile. Your completed Tile class should work with this Main program (Links to an external site.) so that it produces sample output like shown at the end of the program. You can Fork the program to make your own version in Replit, where you can add your Tile.java, or you can copy the program to your own Java development…
Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format. Student number PMark EMark MMark Mar#9186 81 64 72.00 1.2 Create a testStudents class. Do the following: -Write a static method called display() which receives…
C++ PLEASE!!! Complete the EagleNode class destructor. The destructor prints "EagleNode with ", followed by the value of eaglets, then " eaglets is deallocated.". End with a newline. Ex: If the input is 3, then the output is: EagleNode with 3 eaglets is deallocated.
