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...

Create a Bank class with the following properties:
List of bank accounts (List<BankAccount>)
Create the following methods in the Bank class:
AddAccount(BankAccount account): Method to add a new bank account to the list of accounts
RemoveAccount(string accountNumber): Method to remove an existing bank account from the list of accounts
SearchAccount(string accountNumber): Method to search for an existing bank account and return the account details
my code is
// This class represents a bank, which has a list of BankAccount objects as one of its properties.
public class Bank
{
// This property holds a list of BankAccount objects belonging to the bank.
public List<BankAccount> Accounts { get; set; }
// This constructor initializes the list of accounts for the bank.
public Bank()
{
Accounts = new List<BankAccount>();
}
// This method adds a new BankAccount object to the bank's list of accounts.

A Game object knows its name and the number of avators is currently has. It is initialized without Avatars objects. It has a method startGame, which initializes an internal empty list of Avator objects. It has a method to add one Avator object at a time to the Game. It also has a method to remove an Avatar object by the Avatar’s name. A Game object also has a method to animate all its current Avatar objects. Furthermore, it has a method to stopGame, which destroys all current Avator objects in its internal list.
The Avatar class creates simple human-type Avatars, which have attributes such as name, hair color, height, superpower. An Avatar object can change its hair color and superpower. It also has a method that “animates” the avatar. The animate() method should simply be a print message such as “Hello! I am …! I have…. hair and my super power is….!”, using the Avatar’s object variables.
In main program, create 3 different Avatar objects that resemble 3…

- What is the purpose of a constructor? It creates an array of data values associated with an object. It prints all of the information about our object. It returns all data members from an object back to the main method. It allows us to set our own default values when we create an object. in javaarrow_forwardRemove is a method that is defined.arrow_forwardRectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.arrow_forward
- Observer pattern The PhoneModel class stores a phone number as a list of digits, and the Keypad class has this method: public void simulateKeyPresses(int numKeyPresses)(0 that allows the user to enter digits one at a time then save each digit in the list. The Screen wants to respond to each key being entered. Make the model notify the observers whenever a new digit is entered for the phone number. The first observer prints the newest digit out to the screen The second observer prints "Now dialing 12345678901.." out to the screen (where the number is the number the model has). Only the Screen class can print to the screen The model must be decoupled from the Other classes.arrow_forwardpackage assignment; public class Circle2D2 { //data fields specifying the center of the circle private double x, y; //data field radius private double radius; //default circle with (0, 0) for (x, y) and 1 for radius Circle2D2() { this(0, 0, 1); } //circle with the specified x, y, and radius Circle2D2(double x, double y, double radius) { this.x = x; this.y = y; this.radius = radius; } //return x public double getX() { return x; } //return y public double getY() { return y; } //return radius public double getRadius() { return radius; } //return the area of the circle public double getArea() { return Math.PI * Math.pow(radius, 2); } //return the perimeter of the circle public double getPerimeter() { return 2 * Math.PI * radius; } //return true if the specified point (x, y) is inside this circle public boolean contains(double x, double y) { return Math.sqrt(Math.pow(x - this.x, 2) + Math.pow(y - this.y, 2)) < radius; } //return true if…arrow_forwardIt is customary that we write this method to return a string representation of objects in a class. constructor mutator toString accessorarrow_forward
