In JAVA, Given CODE need to be optmized

Optimization and Exception Handling

Refine Source Code for singular bank account program.

Look for code optimization conventions and syntax.

Catch all Exceptions generated during program run-time. The program should never exit with error message.

Bank Account Program

Create an Account Class

We are forming the skeleton of a more complex bank account program.

Create instance variables for balance.You may need more depending on how you implement your bank account program. (We will continue to update the program as the semester continues.)

Create an 2 arrays as a members of the class.

Deposit_Array

Withdraw_Array

We will need methods:

Method for Depositing values into the account.

What type of method will it be?

Method for Withdrawing values from the account.

What type of method will it be?

Method to output the balance of the account.

What type of method will it be?

Method that will output all deposits made to the account.

Method that will output all withdraws made from the account.

Add a new method that will output the contents of the bank account program to a text file.

Program will output the balance of the account.

Program will output the account withdrawals.

Program will output the account deposits.

Use class constructor to initialize values in programmer class for program execution.

Balance Value

Withdrawal History

Deposit History

Output should be like

**************************************

* Bank Account Program: *

* Enter # to run program or Quit *

* 1) Make a Deposit *

* 2) Make a Withdrawal *

* 3) Output balance *

* 4) Output all deposits *

* 5) Output all withdrawals *

* 6) Quit *

**************************************

This is the code that need to be optimized.
