import java.util.Scanner;

public class StringBuilderApp
{
    static Scanner sc = new Scanner(System.in);

    public static void main(String[] args)
    {
        System.out.print("Enter a string: ");
        String s = sc.nextLine();

        StringBuilder sb = new StringBuilder(s);

        int vowelCount = 0;

        for (int i = 0; i < s.length(); i++)
        {
            char c = s.charAt(i);
            if (   (c == 'A') || (c == 'a')
                 || (c == 'E') || (c == 'e')
                 || (c == 'I') || (c == 'i')
                 || (c == 'O') || (c == 'o')
                 || (c == 'U') || (c == 'u'))
            {
                sb.setCharAt(i,
            }
        }
        System.out.println(s);
        System.out.println(sb.toString());
