            // Create a directory

            File noteFile = new File("notes/note.txt");
            if (noteFile.createNewFile()) {
                System.out.println("File 'note.txt' created successfully");
            }

            // List contents of the directory
            File[] files = ____.____();
            if (files != null) {
                for (File f : files) {
                    System.out.println("File: " + f.getName());
                }
            }
            
			// Retrieve and print the absolute path of the file
            System.out.println("Absolute Path: " + ____.____());

        } catch (Exception e) {
            System.out.println("An error occurred: " + e.getMessage());
