How to control tcp connection with java tcp socket programing ??

Question

Hi,
I am connecting a server as using java socket programming.
When server close the connection (socket object) as using close() method ,
I can not detect this and My program continue sending data as if there is a connection with server.
How to catch the closing connection ( socket ) with java socket programming.
My Client program is as following :
import java.io.PrintWriter;
import java.net.Socket;
public class client
  public client()
   * @param args
  public static void main(String[] args)
    Socket socket=null;
    PrintWriter pw=null;
    try
                      socket = new Socket("localhost",5555);
                      pw = new PrintWriter(socket.getOutputStream(),true);
                      int i=0;
                      while (true)
                        i++;
                        pw.println(i+". message is being send.");
                        Thread.sleep(5000);
    } catch (Exception ex)
                      ex.printStackTrace();
    } finally
                      try
                        if(pw!=null)pw.close();
                        if(socket!=null)socket.close();
                      } catch (Exception ex)
                        ex.printStackTrace();
                      } finally
}

I changed the code as following. But I couldn't catch the EOFException when I read from the socket. How can I catch this exception ?
import java.io.BufferedReader;
import java.io.EOFException;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;
public class client
  public client()
   * @param args
  public static void main(String[] args)
    Socket socket=null;
    PrintWriter pw=null;
    BufferedReader bufIn=null;
    InputStreamReader inRead=null;
    InputStream in=null;
    try
                      socket = new Socket("localhost",5555);
                      in = socket.getInputStream();
                      inRead = new InputStreamReader(in);
                      bufIn = new BufferedReader(inRead);
                      pw = new PrintWriter(socket.getOutputStream(),true);
                      int i=0;
                      while (true)
                        i++;
                        try
                          bufIn.readLine();
                          pw.println(i+". message is being send.");
                          System.out.println(i+". message has been send");
                        } catch (Exception ex2)
                          System.out.println(ex2.toString());
                          System.out.println(i+". message could not be send");
                        } finally
                        Thread.sleep(5000);
    } catch (EOFException ex)
                      ex.printStackTrace();
    } catch (InterruptedException ex)
                      ex.printStackTrace();
    } catch (IOException ex)
                      ex.printStackTrace();
    } finally
                      try
                        if(pw!=null)pw.close();
                        if(socket!=null)socket.close();
                      } catch (Exception ex)
                        ex.printStackTrace();
                      } finally
}
