How to serialize a non-serializable in Java?

Question

How can I serialize an object that does not implement Serializable? I cannot mark it Serializable because the class is from a 3rd party library.

Answer 1

Wrap the non-serializable class in a class of your own that implements Serializable. In your class's writeObject method, do whatever's necessary to serialize sufficient information on the non-serializable object so that your class's readObject method can reconstruct it.

Alternatively, contact the developer of the non-serializable class and tell him to fix it. :-)
