Socket Programming Problem

Question

I am using multi threading with socket programming. One thread uses socket's output stream to send the data and the other thread keeps waiting for the data to arrive from that socket's input stream.
Now when the readLine or readObject is excuting on the receiver thread it will be blocked untill data arrives. In which case sending thread will not be able to send the data.
Now is there any way to make the readLine or readObject method non blocking?
Please advise ASAP
thnks

Below is an example of a simple blocking multi-threaded client program that connects to google. I don't believe I've ever experienced a problem like you're describing before while dealing with Java sockets; perhaps this will give you an idea about what's going wrong. One thread reads from stdin, the other (the main-thread of execution) reads from the socket and writes to the screen.
java Test
Then do a GET request to the HTTP server:
"GET / HTTP/1.0"
Then press return again and watch it send you google's root page.
import java.net.*;
import java.io.*;
class Test
    Test()
     try
          Socket mySocket = new Socket("www.google.com", 80);
          BufferedReader myReader;
          final BufferedWriter myWriter;
          myWriter = new BufferedWriter(new OutputStreamWriter(mySocket.getOutputStream()));
          Thread myThread = new Thread()
               public void run()
                   System.out.println("here");
                   try
                   BufferedReader inputReader = new BufferedReader(new InputStreamReader(System.in));
                   String str;
                   while((str = inputReader.readLine()) != null)
                        myWriter.write(str);
                        myWriter.write("\n");
                        myWriter.flush();
                   catch(IOException e)
                    System.err.println("Error reading from stdin.");
                    System.exit(-1);
          myThread.start();
                   System.out.println("there");
          myReader = new BufferedReader(new InputStreamReader(mySocket.getInputStream()));
          String str;
          while((str = myReader.readLine()) != null)
               System.out.println(str);
     catch(IOException hostExcep)
          System.out.println("Host terminated the connection!");
          hostExcep.printStackTrace();
    public static void main(String args[])
     new Test();
}
