JAVA- NETBEANS- 返回带有代码的方法

Question

第一篇文章在这里!

所以我有这段代码:

    static boolean getInternationalCalls() {
    Scanner intercalls = new Scanner(System.in);
    System.out.println("Would the customer like International Calls to be included within their minutes?");
    System.out.println("If yes, please enter Y, if no please enter N below.");

    Scanner scanner = new Scanner(System.in);

    if (scanner.next().equalsIgnoreCase("Y") || scanner.next().equalsIgnoreCase("yes")) {
        System.out.println("Internatinal Calls will be included");
    } else if (scanner.next().equalsIgnoreCase("N") || scanner.next().equalsIgnoreCase("no")) {
        System.out.println("International Calls will not be included");
    } else {
        System.out.println("Invalid character, please enter Y or N");

    }

我自己很困惑，不知道如何编写它的返回语句

返回:

boolean interCalls = getInternationalCalls();

提前致谢! :)

我希望这不是你的作业杰米。你的方法遗漏了很多东西并且有语法错误。请使用像 eclipse 这样的 IDE，会容易得多。

static boolean getInternationalCalls() {
        Scanner intercalls = new Scanner(System.in);
        System.out.println("Would the customer like International Calls to be included within their minutes?");
        System.out.println("If yes, please enter Y, if no please enter N below.");

        Scanner scanner = new Scanner(System.in);
        String input = null;
        while (true) {
            input = scanner.next();
            if (input != null && (input.equalsIgnoreCase("Y") || input.equalsIgnoreCase("yes"))) {
                System.out.println("Internatinal Calls will be included");
                return true;
            } else if (input != null && (input.equalsIgnoreCase("N") || input.equalsIgnoreCase("no"))) {
                System.out.println("International Calls will not be included");
                return false;
            } else {
                System.out.println("Invalid character, please enter Y or N");

            }
        }

    }
