Let’s assume I want to send many messages between 2 programs made in java that use TCP sockets.

I think the most convienient way is to send objects like:

PrintStream ps = new PrintStream(s.getOutputStream());

ObjectOutputStream oos = new ObjectOutputStream(ps);

  some_kind_of_object_here;

  oos.writeObject(some_kind_of_object_here);

 ps.print(oos);

I want to send, strings, numbers, HashMaps, boolean values
How can I do this using fx 1 object that can store all that properties?
I though about ArrayList that is serializable and we can put there everything but is not elegant way.
I want to send different types of data because user can choose from a variety of options that server can do for it.
Any advices?

    Master, you know you can send any serializable object across a socket to another JVM, yes?

    If so, the easiest way is to have a serializable object containing all your objects and then just forward that. A list of objects is probably the most simple. You can then deserialize it on the other side, and process the objects in the list in whatever way you need.

    I would suggest you read up on the serialization technology in Java, so you know all the smart things you can do.
