Question

Write a java program to convert a positive integer value to a roman number. Your program should print a description, prompt them for how many numbers they need to convert and then loop that many times. Each time the program needs to prompt for a number and output the equivalent roman numeral. If the user enters a number less than 1 then output an error message. See sample output below:

You must have a helper class RomanHelper with the following methods. It will be up to you to determine the return type and parameters required for each:

• description: Print the program description to the screen
• getRoman: Converts an integer to a Roman Numeral. No output to the screen should happen here.

Also, you will need to have a driver class RomanDriver with the following methods:

• main: Construct a Scanner object and call the runProgram method.
• runProgram: Prompt the user how many times they would like to run the program and loop that many times calling the getNextNumber method.
• getNextNumber: Prompt for a number to convert and output the result or an error message if the number isn’t positive.

You may add however many additional methods that you would like.
