    {

    char replace;

    Scanner in = new Scanner(System.in);
    // print menu
    for (int i = 1; i <= 5; i++)
    System.out.println(i + "Choose Option" + i);
    System.out.println("6 to Quit");
    // handle user commands
    boolean quit = false;
    int menuItem;

    case 2:
    System.out.println("You've chosen to replace");
    replace = in.toCharArray();
    break;

    case 3:
    System.out.println("You've chosen to shift right");
    // do something...
    break;
    case 4:
    System.out.println("You've chosen lowercase");
    // do something...
    break;
    case 5:
    System.out.println("You've chosen average of array");
    // do something...
    break;
    case 6:
    quit = true;
    break;
    default:
