sockets - How to receive an object on a socketServer in java -

i want send object(array) client server. use objectinputstream , objectoutputstream. however, invokes error, these methods not defined in serversocket class. how resolve situation ??`

public int[] readresponse() throws ioexception, classnotfoundexception{     int[] x = new int[5];        objectoutputstream co = new objectoutputstream(serversocket.getoutputstream()); //here error     objectinputstream ci = new objectinputstream(serversocket.getinputstream()); // here error      co.writeobject(x);        x = (int[]) ci.readobject();      (int = 0; < 5; i++){          system.out.println(x[i]);      }      return x;     } 

a java.net.serversocket not meant used actual input , output; socket listening on server incoming connection requests accepted, resulting in java.net.socket 1 reading , writing.

socket socket = serversocket.accept(); objectinputstream ci =       new objectinputstream(socket.getinputstream()); 

on client side, java.net.socket created calling constructor , connected, via address, client.

socket socket = new socket( address, port ); objectoutputstream co =      new objectoutputstream(socket.getoutputstream());
