Allow User To Enter Roman Numeral And Then Outputs Integer Number Value - While Loop

Write a program called RomanNumeralHelper that allows a user to enter a roman numeral and then outputs the integer number value. Use a Scanner to accept command line input from the user and continually ask for a roman numeral until the user enters Q (or q) to stop. Your solution should NOT use a switch statement.

Here is sample input / output:

Enter a roman numeral [Q | q to quit]: III
>> 3
Enter a roman numeral [Q | q to quit]: IV
>> 4
Enter a roman numeral [Q | q to quit]: V
>> 5
Enter a roman numeral [Q | q to quit]: Q
Good Bye!

This is what I have so far in my code, but I cant get what the user inputs when I want it to output the number.

import java.util.Scanner;
public class RomanNumber4
{
public static void main(String[] args) {
// obtain input from command window
Scanner input = new Scanner(System.in);
