Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9
Assignment 5B: Keeping Score. Now that we know about arrays, we can keep track of when events occur during our program. To prove this, let's create a game of Rock-Paper-Scissors. For those not familiar with this game, the basic premise is that each player says "Rock-Paper- Scissors!" and then makes their hand into the shape of one of the three objects. Winners are determined based on the following rules: Rock beats Scissors Scissors beats Paper Paper beats Rock At the start of the program, it will ask the player how many rounds of Rock-Paper- Scissors they want to play. After this, the game will loop for that many number of times. Each loop, it will ask the player what item they want to use – Rock, Paper, or Scissors. The computer will randomly generate its own item, and a winner will be determined. The game will then save the result as an element of an array, and the next round will begin. Once all the rounds have been played, the program will say "Game Over" and display a list of who…

FaceUp card game In this assignment we will implement a made-up card game we'll call FaceUp. When the game starts, you deal five cards face down. Your goal is to achieve as high a score as possible. Your score only includes cards that are face up. Red cards (hearts and diamonds) award positive points, while black cards (clubs and spades) award negative points. Cards 2-10 have points worth their face value. Cards Jack, Queen, and King have value 10, and Ace is 11. The game is played by flipping over cards, either from face-down to face-up or from face-up to face-down. As you play, you are told your total score (ie, total of the face-up cards) and the total score of the cards that are face down. The challenge is that you only get up to a fixed number of flips and then the game is over. Here is an example of the output from playing the game: FACE-DOWN | FACE-DOWN | FACE-DOWN | FACE-DOWN | FACE-DOWN Face up total: 0 Face down total: -5 Number of flips left: 5 Pick a card to flip between 1…

Can you write it in Java, add comments Create an application containing an array that stores eight integers. Prompt the user to enter the 8 integers. The application should call five methods that in turn (1) display all the integers, (2) display all the integers in reverse order, (3) display the sum of the integers, (4) display all values less than the calculated average value, and (5) display all values that are higher than the calculated average value. Save the file as ArrayMethodDemo
canMove(int x, int y, int destX, int destY, Side s): This method returns true if the player of color s can move the piece at coordinates (x,y) can move to coordinates (destX, destY) on the board in its current state. This means that here you do need to consider this piece’s interaction with other pieces on the board. Conditions for this method to return false are given in the code. public boolean canMove(int x, int y, int destX, int destY, Side s){ /* TODO write a method that checks if a piece at coordinates x,y can move to coordinates destX,destY Conditions for false: - Origin or destination coordinates are outside the board - Piece at origin is null - If source and destination coordinates are the same - Piece at origin is not of the same side as s - You can check this using piece.getSide() - Piece cannot move to the destination by piece movement rules - You should check this using Piece.canMove(destX,…
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).
