Write java program for the following class diagram . The Instructions: 1. This java program is for an application that stores the author (Writer) data of some books and emails. 2. getAuthors() method get the list of authors and store it in a String array. 3. addAuthors() method is used to add an author anytime for book or email. 4. getDate() method get the date of the book or email. 5. getTitle() method can be used to get the title of the book. 6. getSubject() method is used to get the Subject of the email. 7. getTo() method is used to get the information about the mail to whom it is sent. 8. All get methods need to return the values in the corresponding instance variables. 9. Scanner class can be used to set the data for the variables. The programmer can give his/her own methods to set the instance variables.

Please do it in JavaScript or C# 1) Design and implement the class structure for a drawing application. A drawing is made up of a canvas that contains a collection of three different shapes: circles, lines, and boxes. Each shape can be drawn by calling a Draw() method for that shape. The canvas class should also have a draw method that draws all of the shapes it contains. You don’t have to actually draw anything on a screen; you can simulate drawing by writing a message to the console.For example, the code snippet: canvas.Draw();Drawing a circle at...Drawing a line at...etc. (For each shape on the canvas) 2)(Bonus) Consider re-writing the above answer (#1) differently where the canvas does not contain the shapes, but is able to draw any of the three shapes passed to it. Re-design canvas.Draw() if you need to. Your main() program should ask for user input on what shape to draw. Ask once, draw, then exit.could produce something like the following output to the console:

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). •…

CarDealership Class The CarDealership class will simulate a real life automotive dealership. This class will create 3 Car objects and store them in an array named Lot. The class will then display all of the information pertaining to each car (color, make, model, etc.) to the User and allow the User to select one to purchase. Once the User selects a car to purchase, the Car object should be removed from the array (Lot) and another Car object should be put in its place.

Using JAVASCRIPT write an object prototype for a Person that has a name and age, has a printInfo method, and also has a method that increments the persons age by 1 each time the method is called. Create two people using the 'new' keyword, and print both of their infos and increment one persons age by 3 years. Use an arrow function for both methods */ // Create our Person Prototype // Use an arrow to create the printInfo method // Create another arrow function for the addAge method that takes a single parameter // Adding to the age
