How to shrink Java ObjectOutputStream

Question

I have to store a list of Serializable Objects that contains various nested lists of other Objects with many fields, I have noticed that using a normal ObjectOutputstream to store this list requires lot of space also for few entries.

Is there a way to automatically shrink the serializable object before the storage? (without change my Object structure)

Answer 1

You could try compressing the object before you store it using a GZIPOutputStream.
