Java - Sending an object that points to a BufferedImage through a Socket

Question

Me and a group of friends are working on a project in Java, and we need some help regarding sending objects through sockets.

So far, we have achieved to send simple

Answer 1

on each node you can use writeObject() and readObject() check http://java.sun.com/developer/technicalArticles/Programming/serialization/ for more info

essentially it will become

public Node implements Serializable{

    transient BufferedImage buff;//transient make it so it won't be written with defaultWriteObject (which would error)

    private void writeObject(ObjectOutputStream out)throws IOException{
        out.defaultWriteObject();
        //write buff with imageIO to out
    }

    private void readObject(ObjectInputStream in) throws IOException, ClassNotFoundException{
        in.defaultReadObject();
        //read buff with imageIO from in
    }
}
