Q: In the main class, write a method getDataFromFile to read data from a given file. This method should read data from the file, create appropriate objects for the customer and account, save the data into an array.

Make sure to use Scanner, not the BufferedReader.

If the account is Checking, order is CustomerID - LName - FName - Address - City - AccountType - ACCNumber - ACCBalance - DebitNo

If the account is Savings, order is CustomerID - LName - FName - Address - City - AccountType - ACCNumber- ACCBalance

If the account is Business, order is CustomerID - LName - FName - Address - City - AccountType - ACCNumber - ACCBalance - BName - BID

If the account is CreditCard, order is CustomerID - LName - FName - Address - City - AccountType - CreditNo - ACCBalance - MaxCredit
