In this task by using java language , you
should create the moving box example
belwo, then you
should extend the box class and create
a new one called ColoredBox, in this
class you should
override the drawing method, the first
thing you should do is recalling the
original draw
method (as we don't want to change
any of the previous behaviours), then
you should check
if the box collided on the X or Y axis,
if so change the colour of the box
randomly colour.

Cryptography is the practice of encryption. Information Security uses cryptography techniques to encrypt and decrypt data. A simple encryption method might take plaintext and mix up the letters using some predetermined pattern and then use that pattern to decrypt the data for reading.
Ciphers are the algorithms used to put the data into its secret pattern and then systematically decrypt it for reading. This script is going to use a famous simple cipher called the Caesar Cipher. It is a substitution cipher where each letter in the text is 'shifted' in a certain number of places. It uses the alphabet as the primary pattern and then based on the shift number, it would shift all the letters and replace the alphabet with our pattern.
For example, if our shift number was 3, then A would be replaced with D, if we performed a right shift. As an example:
Text = "THE CAT IS VISIBLE AT MIDNIGHT" Ciphertext…

- Implement following three methods that passes sturctural tests: getXStep and getYStep: helper methods, they indicate how far (-1, 0, or 1) have to be taken to take x and y coordinates. moveAndSet: it moves the piece and changes the value of the new position. Use the above helper methods in the code of the method. If the move would make the figure leave the board, cancel the move: the figure remains where it was, the state of the board doesn’t change at all, and the method immediately returns 0. Otherwise, the method returns the old value of the new position, and its value is set to the second argument.

You can read the rules in it's entirety of the Hunt the Wumpus game online to get a better idea of the specifications. It's an actual game. INFORMATION: The object of this game is to find and kill the Wumpus within a minimum number of moves, before you get exhausted or run out of arrows. There is only one way to win: you must discover which room the Wumpus is hiding in and kill it by shooting an arrow into that room from an adjacent room. The Cave The Wumpus lives in a cave of 30 rooms. The rooms are hexagonal. Each room has up to 3 tunnels, allowing access to 1, 2 or 3 (out of 6) adjacent rooms. The attached diagram shows the layout of rooms in the cave. The map wraps around such that rooms on the edges (white cells) have neighbors from the opposite edge (blue cells). E.g., the neighbors of room 1 are rooms 25, 26, 2, 7, 6, and 30, and you could choose to connect room 1 to any of these rooms.

- AVA code OVERVI EW This is a review exercise, so the primary goal of the exercise is to get your mind working and in the correct space.In this activity you will create a imaginary grid of locations that goes from −?≤?≤?, −?≤?≤?, with the coordinate (0,0) being "home". On this grid you will keep track of various animal objects as they move around the grid. Make sure that all animals stay within that grid at all timesincluding when they are created.

Assume the game screen is an n * n square, and the snake starts the game with length 1 (i.e. just the head) positioned on the top left corner. For example, if n = 7 the game looks something like this: BEGINNING In this version of the game, the length of the snake doubles each time it eats food (e.g. if the length is 4, after eating it becomes 8). Create a function that takes the siden of the game screen and returns the number of times the snake can eat before it runs out of space in the game screen.

- Help with codearrow_forwardEmail me the answers to the following questions. If you are not familiar with Peg Solitaire, then look it up online. Peg Solitaire is a game consisting of a playing board with 33 holes together with 32 pegs. In the picture above, the hole in the center is empty and the remaining holes contain pegs. The goal is to remove all the pieces except one, which should be in the center. A piece can be removed by jumping an adjacent piece over it into an empty hole. Jumps are permitted horizontally or vertically, but not diagonally. Your assignment consists of one required part, plus one extra credit part: 1.

- creating a roulette wheel. The pockets are numbered from 0 to 36. The colors of the pockets are as follows: Pocket 0 is green. For pockets 1 through 10, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 11 through 18, the odd-numbered pockets are black and the even-numbered pockets are red. For pockets 19 through 28, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 29 through 36, the odd-numbered pockets are black and the even-numbered pockets are red. Create a class named RoulettePocket. The class's constructor should accept a pocket number. The class should have a method named getPocketColor that returns the pocket's color, as a string. Demonstrate the class in a program that asks the user to enter a pocket number, and displays whether the pocket is green, red, or black. The program should display an error message if the user enters a number that is outside the range of 0 through 36.arrow_forwardGive edgeTo after B is visited.
