Java Serializable Object to Byte Array

Question

(im new to java)

from my searches for Serialization in Java most of the examples document writing to a file or reading from one.

my question is lets say i have a serializable class AppMessage.

I would like to transmit it as byte[] over sockets to another machine where it is rebuilt from bytes received.

how could i achieve this please?

thanks for your insight in advance.

Answer 1

Prepare bytes to send:

ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutput out = new ObjectOutputStream(bos);   
out.writeObject(yourObject);
byte[] yourBytes = bos.toByteArray(); 

Create object from bytes:

ByteArrayIntputSream bis = new ByteArrayInputStream(yourBytes);
ObjectInput in = new ObjectInputStream(bis);
Object o = in.readObject();
