sir,
    i have done a server to client program.it will trasfer the file length from server to client successfully.now i want to make a delay between server to client.so give me a idea to me and to give me a small delay program to add this.
server program:

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

public class server1 {



  public static void main (String [] args ) throws IOException {
   
    ServerSocket servsock = new ServerSocket(13267);
    while (true) {
      System.out.println("Waiting...");

      Socket sock = servsock.accept();
      System.out.println("Accepted connection : " + sock);

     
      File myFile = new File ("D:man.txt");
      byte [] mybytearray  = new byte [(int)myFile.length()];
     
      FileInputStream fis = new FileInputStream(myFile);
      BufferedInputStream bis = new BufferedInputStream(fis);
       bis.read(mybytearray,0,mybytearray.length);
     
      OutputStream os = sock.getOutputStream();
      System.out.println("Sending...");
       os.write(mybytearray,0,mybytearray.length);
     
      os.flush();
      sock.close();
      }
    }
}
client program:

 

   import java.net.*;
import java.io.*;
 
public class client {



  public static void main (String [] args ) throws IOException {
    int filesize=6022386; // filesize temporary hardcoded

    long start = System.currentTimeMillis();
    int bytesRead;
    int current = 0;
   
    Socket sock = new Socket("127.0.0.1",13267);
    System.out.println("Connecting...");

   
    byte [] mybytearray  = new byte [filesize];
    InputStream is = sock.getInputStream();
    FileOutputStream fos = new FileOutputStream("E:man.txt");
    BufferedOutputStream bos = new BufferedOutputStream(fos);
    bytesRead = is.read(mybytearray,0,mybytearray.length);
    current = bytesRead;

   
    do {
       bytesRead =
          is.read(mybytearray, current, (mybytearray.length-current));
       if(bytesRead >= 0) current += bytesRead;
    } while(bytesRead > -1);

    bos.write(mybytearray, 0 , current);
    bos.flush();
    long end = System.currentTimeMillis();
    System.out.println(end-start);
    bos.close();
    sock.close();
  }
}

What if you added the delay after you write to the output stream on the server?

  os.write(mybytearray,0,mybytearray.length);
  Thread.sleep(2000)  // sleep for 2 seconds  
      os.flush();


time interval is ms so 1000 is 1 second
