import java.util.Scanner;


public class PP69

{

public static void main(String[] args)

{

char Letters, a =0, e = 0, i = 0;
char u = 0, o = 0, nonvowels = 0;

String category;
  


Scanner scan = new Scanner (System.in);

System.out.println("Enter a String to be processed for vowels: ");

category = scan.nextLine();


switch (letterschar)
  
   {

case 1 :

a = a++;

   System.out.println("'a' " + a );


break;

case 2 :
   e = e++;
  
   System.out.println( ", 'e' " + e );
break;

case 3:
   i = i++;
  


System.out.println( ", 'i' " + i );
break;

case 4 :
   o = o++;
  

System.out.println( ", 'o' " + o );
break;

case 5 :

   u = u++;

  
System.out.println( ", 'u' " + u );
break;

case 6 :

   nonvowels = nonvowels++;
  

System.out.println( ", nonvowels " + nonvowels);
break;

default:

System.out.println("Error: String contained no characters.");

}


}

}
