Java Substring Comparisons

    Solution in java 15. I had to import ArrayList and Comparator classes.

    public static void main(String[] args) {

    Scanner scan = new Scanner(System.in);
    String s = scan.next();
    int k = scan.nextInt();

    ArrayList<String> lista = new ArrayList<String>();
    for (int i= 0; i < s.length()-(k-1);i++){
        lista.add(s.substring(i,k+i));
    }

    lista.sort(Comparator.naturalOrder());
    System.out.println(lista.get(0));
    System.out.println(lista.get(lista.size()-1));
}

    }
