problem with string

I am trying to create a boolean method using the string matches() method. I want to display the phone number to be true either when the number is 567-345-4567 or just 433-3456. I am also having trouble with the city method, cities with either one name ie. Springfield or more ie. West Haven or Ft. Campbell.

HERE IS THE CODE:

private static boolean isLegalCity(String city) {

        return city.matches("([A-Z]+[a-z]+|\\s[A-Z]+)*");

    }

 private static boolean isLegalPhoneNumber(String phone){

        return phone.matches("[1-9]\\d{2}-[1-9]\\d{2}-\\d{4}");

    }

HERE IS THE COMPLETE CODE:

mport java.util.Scanner;
