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. Invoke the two objects with a name c1 of class Car and t1 of class Truck. • After creating the objects, call all the three methods defined above in both the classes.

- Use Java language ONLY Mastermind is a code-breaking game between two players, the codemaker (in this case the computer) and the codebreaker (the player). How to Play See the following video https://www.youtube.com/watch?v=XwuwWTH39ac. Project Requirements The goal of the project is to implement a text-based/menu-driven Mastermind game. The game will include a menu from which the user will choose: See Rules Play Game See Highest Score Quit When the user chooses to play a game, the computer will generate a three-position code using five colors (Red/Blue/White/Yellow/Green). The player will try to break the code by choosing a color for each of the three positions available - color repeats are allowed. Example: R G B (Red-Green-Blue)The computer will provide feedback using three pins (one for each color) placed in non-related order: Red Pin (R)– A color is part of the code and has been placed on the right position. White Pin(W) – A color is part of the code but has been placed…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…public class Driver { /** * @param args */ static Scanner keyboard = new Scanner(System.in); publicstaticvoid main(String[] args) { Mailbox[] mailboxes = new Mailbox[5]; Mailbox mailbox1 = new Mailbox("gmail"); Mailbox mailbox2 = new Mailbox("outlook"); Mailbox mailbox3 = new Mailbox("icloud"); mailboxes[0] = mailbox1; mailboxes[1] = mailbox2; mailboxes[2] = mailbox3; Email email1 = new Email(); email1.setDate(new Date(2022, 11, 5)); email1.setSubject("Exam2 guidelines "); Email email2 = new Email(new Date(2021, 3, 5), true, "Quiz3 in Ch7"); Email email3 = new Email(); email3.setDate(new Date(2020, 11, 3)); email3.setSubject("Late submission policy"); mailbox2.addEmail(email1); mailbox2.addEmail(email2); mailbox2.addEmail(email3); // System.out.println("Hello!

Popular topics and brands Like most users, Chef didn't know that he could add problems to his personal to-do list by clicking the magic "+" symbol in the upper right corner of each problem page. But once he found out about it, he went crazy and added a lot of problems to his to-do list without looking at their difficulty rating. Rajesh is a beginner and ideally should only try to solve problems strictly below 10001000. Given the difficulty rating list of problems in Chef's to-do list, please help him determine how many of these problems Chef should remove from his to-do list so he is left with only problems with a difficulty rating of less than 10001000.
