public class Main {
  public static void main(String[] args) {
    String[] alphabets = { "A", "B", "C", "D", "E", "F", "G", "H", "I", "J" };

    List<String> list = Arrays.asList(alphabets);

    Collections.shuffle(list);

    for (String alpha : list) {
      System.out.print(alpha + " ");
    }
  }
}
