Question

Design a class named Account (put it in a package named accountspackages) with the following UML diagram:

Account

-customerID: int -customerName: String -balance: double

+setCustomerID(int): void +setCustomerName(String): void +setBalance(double):void +getCustomerID(): int +getCustomerName(): String +getBalance(): double +deposit(double): void +withdraw(double): void +printInformation():void

The method withdraw(double) withdraws a specified amount from the account if the amount is less than or equal the balance, otherwise the method prints the message:

Sorry! The account does not have sufficient funds.

The method printInformation() prints:

    the customerName, the customerID, and the account balance.

Test the Account class by running the following code

(You are not allowed to modify this code):

package accountsdemocom;

public class AccountDemo{

   public static void main(String[] args) {

        Account accountOne = new Account();

        Account accountTwo = new Account();              

        accountOne.setCustomerID(78654);

        accountOne.setCustomerName("John Smith");

        accountOne.deposit(10000.0);

        accountOne.withdraw(25000.0);

        accountTwo.setCustomerID(76234);

        accountTwo.setCustomerName("Jennifer Harris");

        accountOne.deposit(2000.0);

        accountOne.withdraw(150.0);

        accountOne.printInformation();

        accountTwo.printInformation();

        accountOne.withdraw(250.0);

        accountOne.getBalance();     

    }

}

Account.java

package accountspackages;

public class Account {

    private int customerID;
    private String customerName;
    private double balance;

    public Account() {
    }

    public void setCustomerID(int id) {
        customerID = id;
    }

    public void setCustomerName(String name) {
        customerName = name;
    }

    public void setBalance(double balance) {
        this.balance = balance;
    }

    public int getCustomerID() {
        return customerID;
    }

    public String getCustomerName() {
        return customerName;
    }

    public double getBalance() {
        return balance;
    }

    public void deposit(double amount) {
        balance += amount;
    }

    public void withdraw(double amount) {
        if (amount <= balance) {
            balance -= amount;
        } else {
            System.err.println("Sorry! The account does not have sufficient funds.(ID: " + customerID + ")");
        }
    }

    public void printInformation() {
        System.out.println("ID: " + customerID + " Name: " + customerName + " Balance: " + balance);
    }
}

AccountDemo.java

import accountspackages.Account;

public class AccountDemo {
    public static void main(String[] args) {
        Account accountOne = new Account();
        Account accountTwo = new Account();
        accountOne.setCustomerID(78654);
        accountOne.setCustomerName("John Smith");
        accountOne.deposit(10000.0);
        accountOne.withdraw(25000.0);
        accountTwo.setCustomerID(76234);
        accountTwo.setCustomerName("Jennifer Harris");
        accountOne.deposit(2000.0);
        accountOne.withdraw(150.0);
        accountOne.printInformation();
        accountTwo.printInformation();
        accountOne.withdraw(250.0);
        accountOne.getBalance();
    }
}
