Create a main( ) java file to perform the required tasks. Validate a user’s input (a menu option) to ensure its validity. Test and document your program to make sure that all of the required tasks are met. The main( ) creates a menu for a bank manager and a bank customer. For a bank manager, he/she can add information of bank customers and display all customer records. For a bank customer, he/she can make a deposit to a bank account and withdraw money from the account. Hint: The main ( ) could have a static method that allows a bank manager to add customers’ information to a text file. The information consists of Customer ID, Name (full name), and Email Address. Note that a loop should be used to perform the manager's task. As a result from the process, a text file "BankCustInfo.txt" is created. Also, the main( ) could have another static method that allows the bank manager to display all customer records to the screen. Create a class, BankCustomer, that contains attributes such as CustomerID and Balance. The class allows a bank customer to make deposits , withdraw money, display the current balance, and calculate the current interest earned. To calculate an interest earned, an object of the AccountType must be created (see the AccountType in #3).   Create a class, AccountType, that has two attributes: AccountID and InterestRate. The interestRate value depends on the AccountD; if the AccountID is 1 then it is a checking account, and the interest rate is 0.01. If the AccountID is 2 then the account is a saving account and the interest rate is 0.02. Note that this class could be a static class.
