[Text IO && Data Validation practice]

In this assignment, we will get the user?s inputs to open an SavingAccount , CheckingAccount or CDAccount .

• Prompt in the console to get users? input for the file location to save the information.

• Prompt in the console to get users? inputs (balance and duration) to open a CDAccount if the duration is not 0. If the duration is 0, continue to ask the user to open either a SavingAccont or CheckingAccount . After the account creation, save the account info into a text file.

• Write two methods to validate users? input,

double getDouble (Scanner sc , String prompt) - prompt for users' input until a valid double value

int getNonNegativeInt (Scanner sc , String prompt) - prompt for users' input until a valid non-negative integer

• The driver program will generate the account ID.

  SetAnnualInterestRate= 3%, every three months duration the CDAccountCD annual interest rate will raise by 0.5%. For a SavingAccount the AnnualInterestRate is 3%, and 0% for a CheckingAccount.

• Write the account number, balance, annual interest rate and account type into the text file that the user specify.

• By the end of the driver program, format and print out the accounts info reading from the file in the console.

• The user will provide info to create at least three accounts.

• The text file will be created under the project (under the workspace) directory

•
