使用我的swapNotes（）方法，我需要帮助打印“不再交换”

Question

因此，我的scope.Complete()方法将其后的便笺替换为便笺。例如，如果我swapNotes()，则2处于3的位置，而3处于2的位置。这是我的代码https://repl.it/@NischalShresth2/Notebook。在笔记本课堂上第103-108行

swapNotes(2)

笔记本

class Main {
  public static void main(String[] args) {
    Notebook book;
      book = new Notebook();
      book.storeNote("This is my first note.");
      book.storeNote("Second note.");
      book.listNotes();

      book.storeUrgentNote("This is apparently urgent.");
      book.listNotes();

      System.out.println();


      book = new Notebook();
      book.storeNote("one");
      book.storeNote("two");
      book.storeNote("three");
      book.listNotes();
      book.removeNote(0);
      book.listNotes();

      System.out.println();

      book = new Notebook();
      book.storeNote("This is my first note.");
      book.storeNote("Second note.");
      book.storeUrgentNote("This is apparently urgent.");
      book.storeUrgentNote("This is urgent too.");
      book.listNotes();
      book.listUrgentNotes();

      System.out.println();

      book = new Notebook();
      book.storeNote("this is a non-urgent note");
      book.storeNote("this note is also not urgent");
      book.storeUrgentNote("Remember to study for exam!");
      book.listNotes();
      book.demoteNote(0);
      book.listNotes();

      System.out.println();

      book = new Notebook();
      book.storeNote("one");
      book.storeNote("two");
      book.storeNote("three");
      book.storeUrgentNote("four");
      book.listNotes();
      System.out.println();
      System.out.println("Swap notes");
      System.out.println();
      book.swapNotes(3);


      book.listNotes();
  }
