java programming language You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object. Also write a main method for each class in which that class is tested – create…
Computer Graphics Mickey Mouse In this labwork are asked to write a GUI application using AWT. It is highly advised that you build your work and knowledge upon the last labwork. You can watch the small video demo on WebOnline to get a better understanding. In additional to what we did in Lab3 you are going to; • Add a control panel. • Add two buttons to the panel called "Smaller" and "Bigger". • Menubar of this program should have an item called "Set Default"which will reset the values of x, y, dx and dy to the values they had initially. • Modify the action listener according to the buttons and menu item. • Set the title to "Mickey" in the constructor and add your WindowListener. • Modify your paint method to draw 3 ovals which makes up Mickey Mouse silhouette. Smaller ovals have half the radius of the big oval. • The center of the circle is determined by the variables x and y, and the radius of circles should be dependent on dx and dy (which are equal since we are using circles). •…

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.
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…
Library Information System Design and Testing Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher. Write appropriate accessor and mutator methods. Also, write a tester program(Console and GUI Program) that creates three instances/objects of the Library Items class. Extending Library Item Class Library and Book Classes: Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program (Console and GUI Program) with an object of Book class.
