//EXAMPLE CODE THAT NEEDS TO BE EDITED

public class ValidateInput { // validate first name public static boolean validateFirstName(String firstName) { return firstName.matches("[A-Z][a-zA-Z]*"); } // validate last name public static boolean validateLastName(String lastName) { return lastName.matches("[a-zA-z]+(['-][a-zA-Z]+)*"); } // validate address public static boolean validateAddress(String address) { return address.matches( "\\d+\\s+([a-zA-Z]+|[a-zA-Z]+\\s[a-zA-Z]+)"); } // validate city public static boolean validateCity(String city) { return city.matches("([a-zA-Z]+|[a-zA-Z]+\\s[a-zA-Z]+)"); } // validate state public static boolean validateState(String state) { return state.matches("([a-zA-Z]+|[a-zA-Z]+\\s[a-zA-Z]+)"); } // validate zip public static boolean validateZip(String zip) { return zip.matches("\\d{5}"); } // validate phone public static boolean validatePhone(String phone) { return phone.matches("[1-9]\\d{2}-[1-9]\\d{2}-\\d{4}"); } } // end class ValidateInput
