Clone objects using Serialization by byte array java

Question

How to serialize and deserialize objects using ByteArrayOutputStream and ByteArrayInputStream? I need a simple and explicit explanation of this topic.

It's a template of this method:

public class Cloner {

    public <T> T clone(T value) { … }
}

Answer 1

You do just what you said:

1. Create a ByteArrayOutputStream
2. Serialize it to that ByteArrayOutputStream, via new ObjectOutputStream(baos)
3. Get the byte array out of the ByteArrayOutputStream
4. Wrap a ByteArrayInputStream around it
5. Wrap an ObjectInputStream around that
6. De-serialize.

NB your generic signature could usefully be <T extends Serializable>.
