Problem

Your task is to write a program that takes a string of input from the user, and then count the number of vowels that are contained within this string. As output, provide the user with the final count of vowels, as well as the percentage of all characters in the string that these vowels represent. Repeat this until the user either cancels the input, or enters an empty string. For the purposes of this question, you may treat 'y' as though it is always a consonant (ie, just treat 'a', 'e', 'i', 'o', and 'u' as vowels).

I still have to do the solution write-up...

import javax.swing.JOptionPane;

public class test 
{
    public static void main( String[] args )
    {
        String input; //input string
        boolean done = false; //loop control variable
        int vowelCount = 0; //our vowel count
        
        //keep going until we're done
        while( !done )
        {
            //get input from the user
            input = JOptionPane.showInputDialog( "Enter a sentence:" );
            
            if( input == null
