data exchange betweem client server using sockets

Use a DataOutputStrea/SDataInputStream to pass the random numbers.
something like:

import java.net.*;
import java.io.*;

public class Server
{
     public Server()
     {
          try
          {
               //creating server socket binding at port # 3000
               ServerSocket server=new ServerSocket(3000);
               System.out.println("Server binded at "+((server.getInetAddress()).getLocalHost()).getHostAddress()+":3000");
               System.out.println("Run the Client");
               //ready to accept client request
               Socket socket=server.accept();
               //opening the input stream to read data from client connection
               BufferedReader in= new BufferedReader(new InputStreamReader(socket.getInputStream()));
               System.out.println(in.readLine());
               //using output stream responsing data
               DataOutputStream out=new DataOutputStream(socket.getOutputStream());
               for (int i=0; i<8; i++)
               {
                       out.writeInt(Math.random()*10);
               }
               out.flush();
               //closing the in & out streams
               out.close();
               in.close();
          }
          catch(Exception err)
          {
               System.err.println("* err"+err);
          }
               
     }
     
     public static void main(String a[])
     {
          new Server();
     }
     
}

client code
------------------------------------
import java.net.*;
import java.io.*;

public class Client
{
     
     public Client()
     {
          try
          {
               //ceating the socket to connect to server running on same machine binded on port no 3000
               Socket client=new Socket("localhost",3000);
               System.out.println("Client connected ");
               //getting the o/p stream of that connection
               PrintStream out=new PrintStream(client.getOutputStream());
               //sending the message to server
               out.print("Hello from client\n");
               out.flush();
               //reading the response using input stream
               DataInputStream in= new DataInputStream(client.getInputStream());
               for (int i=0; i<8; i++)
               {
                  System.out.println(in.readInt());
               }
               //closing the streams
               in.close();
               out.close();
 
          }
          catch(Exception err)
          {
               System.err.println("* err"+err);
          }
               
     }
     
     public static void main(String a[])
     {
          new Client();
     }
     
}

Here when generating the random number its of double type   [out.writeInt(Math.random()*10);] it say that out can't accept double type values
