Chapter 8, Problem 4SA
Explanation of Solution
Wrapper class:
- As the name suggests, it is a class that “wraps around” a primitive data type and allows the user to create objects instead of variables.
- Static “toString ()” methods:
- Every numeric wrapper class has this method that converts the value to a string.
- This method contains a value as the argument and returns a string.
Example program:
//Declare the main class
public class Sample
{
//Declare the main method
public static void main(String args[])
{
//Declare required variables
int i = 10;
double d = 20...

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:

This constructor will give a generic, default description of the Item. There will be a constructor that takes a string parameter, and it will initialize the Item's description based on the parameter.

- javaarrow_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_forwardFocus on classes, objects, methods and good programming style Your task is to create a BankAccount class(See the pic attached) The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0. get_pin()should return the pin. check_pin(pin) should check the argument against the saved pin and return True if it matches, False if it does not. deposit(amount) should receive the amount as the argument, add the amount to the account and return the new balance. withraw(amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was not. get_balance() should return the current balance. Finally, write a main() to demo your bank account class.
