解决方案
如果您已经有一个预定时间工作，您需要做的就是将所有数据结构用于存储信息那个预订时间和双倍的时间来支持几个独立的预订时间。
例如， ArrayList< String> SeatingAvailable = new ArrayList< String>（）; 将成为：
字典< Time，ArrayList<字符串> > seatsAvailable =
新词典< Time，ArrayList< String> >（）;
时间firstBooking =新时间（13,0,0）;
时间secondBooking =新时间（15,0,0）;
seatsAvailable.put（firstBooking，new ArrayList< String>（））;
seatsAvailable.put（secondBooking，new ArrayList< String>（））;
现在您可以跟踪两个完全独立的座位数组列表。
I am currently developing a booking system as a task for my degree. I need the seating plan to be "saved/stored" for each showing time (radio buttons), so that e.g. If I book 2 tickets at 13:00, I can also book 2 tickets on the same spot for 15:00. What is the best way of doing this?
PS: I'm not making use of a database and I would prefer not to; due to task's requirements.
Here's my code, please run it if you can.

解决方案
If you already have it working for one booking time, all you need to do is take all your data structures used for storing information about that booking time and double them up to support several independent booking times.
For instance, ArrayList<String> seatsAvailable = new ArrayList<String>(); will become:
Dictionary<Time, ArrayList<String> > seatsAvailable =
new Dictionary<Time, ArrayList<String> >();
Time firstBooking = new Time(13,0,0);
Time secondBooking = new Time(15,0,0);
seatsAvailable.put( firstBooking , new ArrayList<String>() );
seatsAvailable.put( secondBooking , new ArrayList<String>() );
Now you can keep track of two completely seperate ArrayLists of seatsAvailable.
