Expert Solution & Answer
Chapter 14.1, Problem 14.2CP
Explanation of Solution
Encapsulation:
- It combines the data and code into a single object
- It helps in restricting access to the methods.
- This helps in preventing the data from being modified due to accident.
- Object’s variable is not directly accessible.
- Underscore helps in preventing the data being accessed directly.
The encapsulation rules in python can be summarized as follows.
| Public method | It is accessible from anywhere. |
| Public variables | It can be accessed from anywhere. |
| Private method | It can be accessed only in their own class |
| Private method | It is accessible only in their class or method. |
- It protects the data from tampering. By declaring the data field as private, direct modifications of properties is prevented...

Java - Encapsulation
A rectangle can be formed given two points, the top left point and the bottom right point. Assuming that the top left corner of the console is point (0, 0), the bottom right corner of the console is point (MAX, MAX) and given two points (all “x” and “y” coordinates are positive), you should be able to draw the rectangle in the correct location, determine if it is a square or a rectangle, and compute for its area, perimeter and center point. To be able to do this, you should create a class Point (that has an x-coordinate and a y-coordinate). Also, create another class called Rectangle. The Rectangle should have 2 points, the top left and the bottom right. You should also implement the following methods for the Rectangle:
display() - draws the rectangle on the console based on the samplearea() - computes and returns the area of a given rectangleperimeter() - computes and returns the perimeter of a given rectanglecenterPoint() - computes and returns the center point…

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:

- C# Code: There are two A, B players playing the game. Player A is angry with him, and player B is angry with him. Both s and t include only small English letters and are of equal length. A makes the first move, then B, then A, and so on. Before the start of the game, players are familiar with the content of both the letter s and t characters. These players form one rope during the game. Initially, the character unit w is empty. In each move, the player removes any single letter from the alphabetical order in order and adds this letter any (any position) to the letter w you can add a character to any index. Please refer to the Definitions for more specifications). If in any stage of the game, the character unit w is more than 1 length and is a palindrome, the player who made the last move wins. If even after the end of the game (i.e., when both s and t are empty strings), no one can make a unit of characters w a palindrome, and then player B wins.

- Define the class given from the picture using javaarrow_forwardComputer Science I need the code for this in Alice programming Faery Magic Create a world that has at least 5 different objects from the Furniture Gallery and one Faery from the Fantasy/Faeries Gallery. The Faery has the power to make an object disappear. Everything that the faery touches disappear from the scene. Create an interactive game where the user can click one object at a time from the scene; then, the faery faces that object and moves toward it. Write a recursive method named CheckDistance, that checks whether the faery is very close to the object clicked by the user. If it is, the faery bends over to touch the object. After the faery touches the object, the object disappears (this is the base case of the recursion). If the faery is not yet close enough to the object to be able to touch it, the faery moves a small distance forward and the CheckDistance method is recursively called (this is the recursive case of the recursion).

Pennies are tossed onto a board that has certain areas marked with different prizes. For example: The prizes available on this board are puzzle, game, ball, poster, and doll. At the end of the game, if all of the squares that say BALL are covered by a penny, the player gets the ball. This is also true for the other prizes. The board is made up of 25 squares (5 x 5). Each prize appears on three randomly chosen squares so that 15 squares contain prizes.In Python, create a PennyPitch application that displays a Penny Pitch board (use [ and ] to indicate squares) with prizes randomly placed and then simulates ten pennies being randomly pitched onto the board. After the pennies have been pitched, the application should display a message indicating which prizes have been won, if any.arrow_forward
