public class Kboat20LetterSet
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.println("Enter any 20 letters");
int vc = 0, cc = 0;
for (int i = 0; i < 20; i++) {
char ch = in.next().charAt(0);
ch = Character.toUpperCase(ch);
if (ch == 'A' ||
ch == 'E' ||
ch == 'I' ||
ch == 'O' ||
ch == 'U')
vc++;
else if (ch >= 'A' && ch <= 'Z')
cc++;
}
System.out.println("Number of Vowels = " + vc);
System.out.println("Number of Consonants = " + cc);
