Solution in Java8 (OpenJDK 1.8.0) (judge verdict: Accepted)

import java.util.Scanner;

//c が母音であるとき、vowel と、そうでないとき consonant と出力せよ
public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		char c = sc.next().charAt(0);
		
		if(c == 'a' || c == 'i' || c == 'u' || c == 'e' || c ==  'o') {
			System.out.println("vowel");
		} else {
			System.out.println("consonant");
		}
