- Create a Point class to hold x and y values for a point. Create methods show(), add() and subtract() to display the Point x and y values, and add and subtract point coordinates. Create another class Shape, which will form the basis of a set of shapes. The Shape class will contain default functions to calculate area and circumference of the shape, and provide the coordinates (Points) of a rectangle that encloses the shape (a bounding box). These will be overloaded by the derived classes; therefore, the default methods for Shape will only print a simple message to standard output. Create a display() function for Shape, which will display the name of the class and all stored information about the class (including area, circumference and bounding box). Build the hierarchy by creating the Shape classes Circle, Rectangle and Triangle. Search the Internet for the rules governing these shapes, if necessary. For these three Shape classes, create default constructors, as well as constructors…Create a class circle class with radius as data member. Create two constructors (no argument, and two arguments) and a method to calculate Circumference.Create a Point class to hold x and y values for a point.

- Finish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.Create a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…Add the following constructor to your Rectangle class: public Rectangle(Point p, int width, int height) Construct a new Rectangle whose top-left corner is specified by the given Point and with the given width and height.
- Create one more method in the Starship class: encounter(self, enemy_ship) This method takes in self, along with another Starship object. The method should simulate a battle between the two ships. How the method is implemented is almost entirely up to you. You could take in user input for each crew member, or have them each act randomly from the available options, or specify exactly what a given crew member of each type should do. The only requirements are as follows: Each crew member on each ship should get at least one “turn” before the battle is complete. If the crew member is Injured on their turn, they should do nothing. You may assume that each ship will have at least one crew member uninjured when the encounter begins. You shouldn’t make any assumptions about how many crew members there will be on a given ship, where they will start, or about which subclasses will be present - it’s possible that you’ll have test cases including a ship with no captain, or no doctor.…Create a PhoneListing class that uses the Name class for one of its instance variables. Remember the instance data in the Name class is private to the class and must be accessed through its methods.Add additional instance variables to the PhoneListing class for the phone number. The phone number should be broken down into three parts, area code, city code, and local code.Create all appropriate methods for the new class, including the following three methods: equals(PhoneListing):boolean, an equality of state method that returns true if the objects contain the same name and phone number. compareTo(PhoneListing):int, a comparison method that returns -1 if the calling PhoneListing object should precede the argument PhoneListing object, 1 if the calling PhoneListing object should come after the argument PhoneListing object, and a 0 if they are equal. Use last, first, middle, phone number as the ordering values. example:Adams, Alex, Henry, (609)473-2101 Adams, George, Henry, (509)373-1101…Write a Rectangle class to represent rectangles, with two data fields (width, height) and four methods (input data, display data, calculate and return area, calculate and return perimeter). Write another class to test all methods of the Rectangle class.
- Create a Book class with attributes such as book title, author, and price. Implement a parameterized constructor to initialize these attributes. Now, extend the functionality of the Bookstore class by adding a new method called 'addBook.' This method should allow the addition of custom books to the bookstore's inventory. The method should take three parameters: title, author, and price. Implement this method to ensure that the bookstore's inventory is updated accordingly. Instantiate a new object of the bookstore, naming it 'ReadersHaven, utilizing the extended class with the newly added 'addBook' method. Your next step is to add three distinct custom books to 'ReadersHaven-for example, 'The Silent Observer® by Jane Doe, priced at $20.99, Adventures in Wonderland" by Lewis Carroll, priced at $15.50, and 'Programming Mastery by John Coder, priced at $30.75. To conclude, utilize a 'displayinventory' method to showcase the updated information about 'ReadersHaven." Verify that the output…1) Create a "Car" class that keeps car ids and prices. And create a "Galleries" class that holds the car list for a particular gallery. In this class there should be methods for get / set and print for car name, car number and car list. Adding / Removing Cars to the List in This Class should have methods. And create another method to find and print the IDs of Cars with Car Segment equal to X. (print (X)). Car Prices are as follows according to the segments. 0-19999 -> Z20000-29999 -> Y30000-44999 -> T45000-100000 -> P Apply the Car list using "Single Linked List"(Node, newNode, head). The program should be written in JAVA.Define the Circle2DYourLastName class that contains: Two double data fields names x and y that specify the center of the circle withgetter methods. A double data field radius with getter method. A constructor that creates a circle with specified x, y, and radius. A method findTypeOfIntersection to determine and return types ofintersection as string (contained, overlap, or separate).Design a user class that prompts the user to enter the coordinates of the center andradius of two circles and displays the type of intersection. Allow the user to repeat yourprogram using a ConfirmDialog Box.
