// TODO #3: Write the code here to test for the input name error condition :

//String must contain only alphabetic characters, lower/upper case

//plus optionally 1 character from this set: (space, quote (') , dash(-), dot(.) )

// The optional characters, if present, cannot be at the end of the string or at the beginning

// For example, you might have :

// O'Connor, St. James, St-Armand

// But not:

// Jeremy' , -John, John.

// and throw a new BadAccountInputException with the message 'Bad Name Format'

// This exception will be caught in the calling method in AccountFileSaver class.

// Note that this test is used in checking the setters for both the first

// and last names, below.

// Return true only if no error occurs at all in the method

if(!name.contains("'")||!name.contains(".")||!name.contains("-")) {

if(!name.matches("^[a-z]*")||!name.matches("^[A-Z]*"))
