Chapter 8, Problem 3SA
Program Plan Intro
Wrapper class methods:
- The static “toString” method converts to a string from a number.
- The method that accepts number as its argument.
- It returns a number’s string representation.
- The “toBinaryString”, “toHexString”, and “toOctalString” accepts integer as argument.
- It returns string representation of number converted into binary, hexadecimal and octal.
- The “MAX_VALUE” and “MIN_VALUE” stores maximum and minimum value for a specific data type.
- Hence, the methods used to convert a number from decimal to another system are “toBinaryString”, “toHexString”, and “toOctalString”.

Description
In this assignment you will write a program that shows the valid moves of chess pieces. Your program will draw a board with 64 squares using the traditional layout, next ask the user to choose a move, and then, depending on the user's choice, redraw the board with the selected chess piece and its valid moves. Please see the examples of valid moves of chess pieces and the traditional chess board layout below:
At the beginning, your program should draw an empty chess board and prompt the user to enter a move:

Each of the numeric wrapper classes has a static toString method. What do these methods do?
A for construct is a kind of loop that operates on items included in a list. Because of this, it continues to operate for as long as there are objects to be processed in the system. Is this statement correct or does it include an error?

- Monty Hall Problem – Coding Lab In this lab, you will write a code that simulates the Monty Hall Game Show. Thegame host gives the participant the choice of selecting one of three doors. Twodoors has a goat behind them and one door has a prize. The set of choices arerandomized each round. The participant needs to select the door with the prizebehind it. When the participant selects a door, the game host reveals a door with agoat behind it. The game host opens a door (different from the one selected by theparticipant) that has a goat behind it. The participant is then given the option tochange their choice. When you run your code, the code would display a message prompting the user toinput their door choice, labelled as 1, 2, and 3. Then the code will display a doornumber (different from the one the user picked) with a goat behind it and ask theuser if they would like to change their choice. The code then displays a message onwhether the user guessed the correct door.

You do not know the password, but as the correspondence value, you can write a method that compares the characters one by one and returns how many characters the given chromosome differs from the password.arrow_forwardPart 2. fill Method Define a method in simpy named fill. Its purpose is to fill a simpy's values with a specific number of repeating values. The fill method will have two parameters following self: 1. The float value you are filling the values list in with. 2. The int number of values to fill in. The fill method is procedure-like in that it returns None and mutates the object the method is called on. After calling fill, the length of the Simpy object's values should be equal to the second argument given to fill. For example, consider the following usage and expected printed output, given inline, below: twos = Simpy([]) twos.fill(2.0, 3) print("Actual: ", twos, Expected: Simpy([2.0, 2.0, 2.0])") twos.fill(2.0, 5) print("Actual: ", twos, " - Expected: Simpy([2.0, 2.0, 2.0, 2.0, 2.0])") mixed = Simpy([]) mixed.fill(3.0, 3) - Expected: Simpy([3.0, 3.0, 3.0])") print("Actual: ", mixed, mixed.fill(2.0, 2) print("Actual: ", mixed, Expected: Simpy ([2.0, 2.0])") Pythonarrow_forward

- Charge Account Validation Using Java programming Create a class with a method that accepts a charge account number as its argument. The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845 4520125 7895122 8777541 8451277 13028508080152 4562555 5552012 5050552 7825877 12502551005231 6545231 3852085 7576651 7881200 4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.arrow_forwardHow can you prevent class fields from being corrupted by mistake?arrow_forwardPython language Write a initializer method for the class Test.
