Question

Suppose I have an OutputStream (and not an ObjectOutputStream). Is is possible to send a serialized object using the write method? Thanks!

Answer 1

Here is what you do to serialize the object:

new ObjectOutputStream(outputStream).writeObject(obj);

If you want to control the byte[] output:

ByteArrayOutputStream buffer = new ByteArrayOutputStream();

ObjectOutputStream oos = new ObjectOutputStream(buffer);

oos.writeObject(obj);

oos.close();

byte[] rawData = buffer.toByteArray();
