Question

LAB2 PART 1
FOR THE DATA TYPE CLASS:
If you do not have UML of class Account_yourLastName, you should do that first

Basesd on the UML, provide the code of data type class Account_yourLastName to hold the information of an account with account number (String), name (String), balance (double), with no-argument constructor, parameter constructor

Also, define some methods to handle the tasks: open account, check current balance, deposit, withdraw, and print monthly statement. At the end of each task we have the output as below:

Task OPEN ACCOUNT

For example: account number is 1567794657, name Mary Lane, and start balance is 500

-display the output:

OPEN NEW ACCOUNT – JAMES SMITH BANK

Account Number: 1567794657

Name:Mary Lane
Balance:500.0

Task CHECK CURENT BALANCE - Display the output:

CHECK CURRENT BALANCE – JAMES SMITH BANK

Account Number: 1567794657

Name:Mary Lane
Current Balance:500.0

Task DEPOSIT -If deposit amount is 200 to above account, display the output:

DEPOSIT – JAMES SMITH BANK

Account Number: 1567794657

Name:Mary Lane
Balance:500.0

Deposit amount: 200.0

New Balance:700.0

Task WITHDRAW -If withdraw amount is 300, display the output:

WITHDRAW – JAMES SMITH BANK

Account Number: 1567794657

Name:Mary Lane
Balance:500.0

Withdraw: 300.00

New Balance: 400.0

Task PRINT MONTHLY STATEMENT - dIsplay the following output:

MONTHLY STATEMENT – JAMES SMITH BANK

Account Number: 1567794657

Name:Mary Lane
End Balance:700.0

FOR THE DRIVER CLASS: provide the pseudo-code or flowchart then write the code for the BankService_yourLastName to provide the application of a bank service. First, provide the following menu of tasks:

BankService_Smith.java

MAIN MENU – JAMES SMITH BANK

1. Open new account

2. Check current balance

3. Deposit

4. Withdraw

5. Print monthly statement

0. Exit

If users select other task before opening account then, the program will display message box:“You should open account first”

Task 1: Open new account:
-After reading all information of the account entered from the keyboard to create an account-Create the object of the class Account
-then display the output by calling the method Create New Account

Task 2: Check current balance
-call the method Check Current Balance from data type class to display the output

Task 3: Deposit
-ask users for depoit amount, call the method deposit from data type class to display the output

Task 4: Withdraw
-ask users for withdraw amount, call the method withdraw of class Account_yourLastName

Task 5: Print monthly statement -print the monthly statement

EXIT
When users exit display the message box:

“Thank you. The application is terminating..”

Requirement:
-Get the output of the task Monthly Statement then paste it in the file with pseudo-code -write the comment on each part in both classes

COMPILE AND RUN THE PART1 TO GET THE OUTPUT
