Yes it is Poosible to send an Object using Sockets,

for example refer to below given code snippet.

ObjectOutputStream out = new ObjectOutputStream
(socket.getOutputStream());
out.flush();
ObjectInputStream in = new ObjectInputStream
(socket.getInputStream());
type=(String)in.readObject();
out.writeObject("ok");
in.close();
out.close();
socket.close();

Objects that implement Serializable may be sent across a socket connection using an ObjectInputStream and ObjectOutputStream combination.

Here are the steps to follow:

First, define an object to send. As an example, we can define a class called Message to encapsulate our communications:
public class Message implements Serializable {
private int senderID;
private String messageText;

public Message(int id, String text) {
senderID = id;
messageText = text;
}
public String getText() {
return messageText;
}
}
Next, instantiate the object, wrap the socket's streams in object streams, then send the message across the socket:
Message sayhey = new Message("123456789", "Hello");

Socket socket = new Socket(host, port);
ObjectOutputStream out = new ObjectOutputStream(socket.getOutputStream());

out.writeObject(sayhey);
On the other side of the socket, the message can be retrieved and used by invoking methods on the returned object:
ObjectInputStream in = new ObjectInputStream(socket.getInputStream());
Message messageObject = (Message) in.readObject();
String messageText = messageObject.getText();
