public class MoveNthWord {

    public static String moveNthWordToEndOfString(String s, int n) {
        // Split on whitespace (one or more spaces)
        String[] parts = s.trim().split("\\s+");

        if (n < 0 || n >= parts.length) {
            return s; // Out of range → return original
        }

        // Convert to a mutable list
        java.util.List<String> words = new java.util.ArrayList<>();
        java.util.Collections.addAll(words, parts);

        // Remove the nth word and append it at the end
        String moved = words.remove(n);
        words.add(moved);

        // Rebuild the string
        return String.join(" ", words);
    }

    public static void main(String[] args) {
        String s = "Would you like to know more? (Explore and learn)";
        int n = 2;

        String result = moveNthWordToEndOfString(s, n);
        System.out.println(result);
    }
}
