在 Java 的 RecordStore 中表示和存储数据的好方法是什么？
鉴于 Java ME 不允许反射并且相当精简，那么在 RecordStore 中存储数据的好方法是什么？我想到设计一个类似 JSON 的语法适配器类，它可能需要每个要存储值的类来实现 Hashtable + 可能需要一个额外的正则表达式库，因为即使它已被删除。
如果你想知道我到底为什么需要它，那是为了一项任务。因此，真正的困境在于，在原则上编写相当不必要的大块正确代码，还是在知道没有人会因为维护这些垃圾而对所有内容进行硬编码之间。但是，我身上有良好原则的人倾向于前者。
编辑：我应该详细说明 - 我想将对象的数据存储在 RecordStore 中，因此我尝试设计一种方法将对象表示为字符串，然后可以将其转换为字节数组。
Given that Java ME allows for no reflection and is quite stripped down, what would a good approach to storing data in a RecordStore be? I thought of devising a JSON-like syntax adapter class which would probably require every class whose values are to be stored to implement a Hashtable + might probably require an additional regex library as even that's been taken away.
If you're wondering why on earth I need it, it's for an assignment. So the dilemma is really between writing a rather unnecessarily large chunk of proper code as a matter of principle or hardcoding everything in knowing nobody has to suffer through maintenance of this junk down the line. But, the good principles person in me is leaning towards the former.
EDIT: I should have elaborated — I'd like to store object's data within the RecordStore, so I'm trying to devise a method to represent an object as a string which can then be converted into a byte array.

对于要保存在 RecordStore 中的每个对象，将其削减为其组件字符串和基元，然后使用包装在
DataOutputStream中的ByteArrayOutputStream将其序列化为字节数组。然后将此字节数组写入 RMS。使用包装在
DataInputStream中的ByteArrayInputStream反转该过程以取回对象。For every object you want to save in the RecordStore, pare it down to its component Strings and primitives, then serialise it to a byte array, using a
ByteArrayOutputStreamwrapped in aDataOutputStream. Then write this byte array to RMS.Reverse the process using a
ByteArrayInputStreamwrapped in aDataInputStreamto get the object back.
