Shape Classes Design classes Square, RightTriangle , and Triangle that encapsulate three geometric shapes. Each class should implement a method void draw (int x, int y) that “draws" a square, a right triangle, or an equilateral triangle (a triangle with three equal sides), respectively. See Figure 2. The parameters x and y specify the relative position of the figure: y lines down and x spaces acro from the current position of the screen cursor. The instance variables of each class are: int rows , the number of rows that comprise the figure, and char character , the keyboard character used for drawing the figure. Each shape of Figure 2 consists of five rows. The drawing characters are *** for the square, %' for the right triangle, and #' for the equilateral triangle. Shape (abstract) int rows char character Shape() Shape(int x, char c) int get rows() char getCharacter() void setRows(int x) void setCharacter(int x) void draw(int x, int y) (abstract) Square() Square(int x, char ch) void…

Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).
Rectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.

Define class Shape, 2DShape and 3DShape as per UML class diagram given. 2. Define all mutator methods(set and get) for all classes. 3. Define methods calArea() with formula area - width * length for 2DShapes. 4. Define methods calArea() with formula calvolume, volume = width*length*height for 3DShapes. In the main program, declare and set data in 1 object of 3DShapes. Create an array OR ArrayList of 2DShapes, set and display the info of all objects as shown in the output. 5.

Area of a rectangle = length * width Create a Class that calculates and prints out the area of a rectangle. Then write code that creates an object of this Class in which given the length and width, it calculates and prints out the area of a rectangle. Your output should look like this: Area of rectangle: 87
