vowel count in codeabbey

Question

I'm working on the vowel counting problem at coedabbey, but my solution doesn't seem to be working. Here's what I'm doing:

import java.util.Scanner;

public class Solution {
    private static Scanner input;

    public static void main(final String[] args){

        input = new Scanner(System.in);
        int amount = input.nextInt();

        for(int i = 0 ; i < amount ; i++){
            int sum = 0;
            String nowa = input.nextLine();

            for(int j = 0; j < nowa.length() ; j++){
                char x = nowa.charAt(j);

                if(x == 'a' || x == 'o' || x == 'u' || x == 'i' || x == 'e' || x == 'y'){
                    ++sum;
                }
            }
            System.out.println(sum+ " ");
         }
    }
}

But it does not do the right number of lines, and always outputs 0 for the count for a line after I enter the input. After that it does one fewer line than I expected.

An example run might look as follows:

> java Solution
> 3
0
> hello
2
> george
3

But, I wanted to enter another line because I said "3" at the beginning.

Answer 1

Skip a line after nextInt() as it doesnt consumes whole line it consumes only token

 int amount = input.nextInt();
 input.nextLine();

Demo

Answer 2

Instead of String nowa = input.nextLine(); try String nowa = input.next();.
