Work on the following: Create three interfaces with the names "InterfaceOne," "IrnterfaceTwo," and "Interfacelhree" In the first interface, declare a method (signature only) with a name "updateGear()." In the second interface, dedare a method (signature only) with a name "accelerate()." In the third interface, dedare a method (signature only) with a name "pusherake()." Create two classes Car and Truck that implement these three interfaces at one time. Define a new method "currentSpeed()" in both the classes to find the current speed after the brake. • Define all the three methods inside each class. The data to these methods will be provided during the object creation.

The oval should automatically resize and reposition itself when the window is resized. In this activity you will start with our OvalDraw application in our sample code, review the code, and then make incremental improvements to the application. Be sure to make the resulting application uniquely your own by adding standard comments at the top application (i.e. your name, class, etc.), changing the names of variables, and adding small features. Finally, be sure to save your work as you will often be asked to submit it as part of an assignment. Be sure to review the example OvalDraw project in the Java section of our example code repository. Requirement 1:…Purpose To review interfaces Directions Your task for this lab is to implement and test a class to store ratings of items. Your Rating class should have the following fields and methods: private double sumOfRatings - the sum of all of the ratings private int raters - the number of people who have rated an item public Rating () initialize both fields to zero public Rating (double sumofRatings, int raters) - initialize the fields to the parameter values public void addRating (double newRating) - increase the sumOfRatings by newRating and increase the number of raters by one public double getAverageRating () return the average rating; if there are no raters so far, return 0.0 public String toString() - display the average rating and how many reviews it is based on; for example, if the sum of the ratings is 32 and that is based on ratings from ten people, the toString method will return "3.2 based on 10 reviews"

- Language is c++ Assignment 6 C: Minesweeper - Simplified. For many years, computers sold with the Windows operating system would contain a game called M inesweeper. The player would be presented with a grid, where they would have to click an empty part of the map. If they clicked on a hidden mine, the game would be instantly over. However, if they clicked a safe spot, a hint about nearby mines would be displayed and the player would click another spot. The goal would be to flag all the hidden mines without hitting one. (As an aside, many people did not know these rules and just clicked around randomly until they hit a mine)We will be developing a simplified version of this game. You will prompt the user for a grid size and then created a 2D array with equal width and height (C++ students: Check the Appendix for more information on how to do this). You will initialize the 2D char array with each element equallying a ‘?’ symbol. You will then randomly generate one “mine” value per…1. Dummy GUI Application by Codechum Admin A GUI Application is an application that has a user interface that the user can interact with. For this program, we will be simulating this behavior. First, implement another class called Checkbox which implements the Clickable interface which has only one method: public void click(). The Checkbox will have the following properties: private boolean isChecked (defaults to false upon the creation of object) private String text Additionally, it should have the following methods: the implementation of the click() method If the isChecked is currently false, this will set the isChecked to true and will then print the message "Checkbox is checked". If it is currently true, this will set the isChecked to false and will then print the message "Checkbox is unchecked". Note that the messages to be printed should have also print a new line at the end. an override of the toString() method which returns the message: "Checkbox ({text} - Clicked…OBJECT ORIENTED IN JAVA Example for VERSION 1: Welcome to Nick's Neon Tubing Calculator Enter the shape type (R, S, C, T, L, Q): R Enter Height and Width of Rectangle: 6.5 12 The perimeter of a 6.5 x 12 rectangle is 37.0 Enter the shape type (R, S, C, T, L, Q): C Enter Diameter: 12 The circumference of circle with diameter 12 is 37.7 Enter the shape type (R, S, C, T, L, Q): Q Shapes Needed 37.0 - rectangle, 6.5 x 12 37.7 - circle, diameter 12 --------------------------- 74.7 Total Length Thank You there is a version 2 as well, if you look at the pictures.

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:
