在预订菜单中，我主要有 3 个选项：a、b 和 c。选项 'a' - 选择房间类型。5种不同的房型可供选择。选项“b”- 为每个房间选择附加组件。每个附加组件都可以额外付费选择。选项 'c' - 从进行预订页面返回到主页
我的程序需要显示 5 种不同类型的房间。此时客户只能选择选项“a”、“b”或“c”。
如果客户在选择房间时输入了无效的号码（包括1到5），系统会给出错误信息并提示用户重新输入。一旦用户输入了他/她想要的房间类型，他们可以继续输入每个房间的数量房间类型。选择房型后，系统会提示您选择每种房型的附加组件。
这是我下面的代码。当用户选择选项“b”时，我无法从选项“a”获取存储在整数数组列表中的附加组件数量。
我初始化了 2 个数组列表，但我不确定它们是否正确。第一个数组列表是存储房间类型和日期的字符串。第二个数组列表是整数，它存储房价、房间需求数量、附加组件数量、晚数、用户选择的附加选项和附加组件的数量。
我对编码很陌生，所以需要帮助。
