                       + "\n\nEnter your choice (1-7): ");
        while (!keyboard.hasNextInt() || keyboard.nextInt() < 1 || keyboard.nextInt() > 7){
            System.out.println("Invalid Input");
            System.out.println("Specialty Auto");
            System.out.print("\n(1) Display the Entire automobile list"
                               + "\n(2) Display the entire automobile inventory sorted by year"

        keyboard.nextInt();
        }       

        return keyboard.nextInt();

}

这是我所拥有的，我需要验证以确保用户输入数字1到7，但也没有输入任何字母，它的工作类型。当我测试它时，我没有做出故意的错误（使用数字1）我必须在正确的对话框出现之前输入3次。我做错了什么？
