Question

This is the question -

Write a program that inserts parentheses, a space, and a dash into a string of 10 user-entered numbers to format it as a phone number. For example, 5153458912 becomes (515) 345-8912. If the user does not enter exactly 10 digits, display an error message. Continue to accept user input until the user enters 999.

This is the code I have - However it isn't seeming to accept my output. It doesn't like what I have for some reason -

import java.util.*;

public class PhoneNumberFormat {

public static void main(String[] args) {

// Write your code here //Create an instance of Scanner class

Scanner keyboard=new Scanner(System.in);

//declare string data type variables

String phoneNumber= "";

String formattedPhoneNumber="";

/*Run the loop infinitely until user enters 999 to exit from program*/

while(true)

{

System.out.println("Enter phone number: ");

phoneNumber=keyboard.nextLine();

//exit from the program if enters 999

if(phoneNumber.equalsIgnoreCase("999"))

System.exit(0);

if(phoneNumber.length() < 10)

System.out.println("Invalid phone number .");

else {

/* append the ( +xxx++) three characters to formattedPhoneNumber */

formattedPhoneNumber+= "(" + phoneNumber.substring(0, 3) + ")";

//append next three characters

formattedPhoneNumber+=phoneNumber.substring(3, 6);

formattedPhoneNumber+="-";

/* Then append rest of the phoneNumber to the formattedPhoneNumber */

formattedPhoneNumber+= phoneNumber.substring(6, phoneNumber.length());

//print the formatted phone number

System.out.println(formattedPhoneNumber);

}//end of else case

}

This is what the program is showing as it counts it wrong -
