How to transfer a zip file through socket programming in java? -

i new socket programming. did simple program transfer zip files creating empty zip , doesn't transfer files. can me please?

client.java

package filetransfer; import java.io.bufferedoutputstream; import java.io.fileoutputstream; import java.io.ioexception; import java.io.inputstream; import java.net.socket;  public class simpleclient {    public final static int socket_port = 13267;         public final static string server = "00.200.00.00";     public final static string        file_to_received = "d:/projects/transferred.zip";      public final static int file_size = 6022386;      public static void main (string [] args ) throws ioexception {     int bytesread;     int current = 0;     fileoutputstream fos = null;     bufferedoutputstream bos = null;     socket sock = null;     try {       sock = new socket(server, socket_port);       system.out.println("connecting...");        // receive file       byte [] mybytearray  = new byte [file_size];       inputstream = sock.getinputstream();       fos = new fileoutputstream(file_to_received);       bos = new bufferedoutputstream(fos);       bytesread = is.read(mybytearray,0,mybytearray.length);       current = bytesread;        {          bytesread =             is.read(mybytearray, current, (mybytearray.length-current));          if(bytesread >= 0) current += bytesread;       } while(current < file_size);        bos.write(mybytearray, 0 , current);       bos.flush();       system.out.println("file " + file_to_received    + " downloaded (" + current + " bytes read)");     }     {       if (fos != null) fos.close();       if (bos != null) bos.close();       if (sock != null) sock.close();     }   }  } 

server.java

package filetransfer;  import java.io.bufferedinputstream; import java.io.file; import java.io.fileinputstream; import java.io.ioexception; import java.io.outputstream; import java.net.serversocket; import java.net.socket;  public class simpleserver {    public final static int socket_port = 13267;     public final static string file_to_send = "c:/users/public/pictures/sample pictures.zip";      public static void main (string [] args ) throws ioexception {     fileinputstream fis = null;     bufferedinputstream bis = null;     outputstream os = null;     serversocket servsock = null;     socket sock = null;     try {       servsock = new serversocket(socket_port);       while (true) {         system.out.println("waiting...");         try {           sock = servsock.accept();           system.out.println("accepted connection : " + sock);           // send file           file myfile = new file (file_to_send);           byte [] mybytearray  = new byte [(int)myfile.length()];           fis = new fileinputstream(myfile);           bis = new bufferedinputstream(fis);           bis.read(mybytearray,0,mybytearray.length);           os = sock.getoutputstream();           system.out.println("sending " + file_to_send + "(" + mybytearray.length + " bytes)");           os.write(mybytearray,0,mybytearray.length);           os.flush();           system.out.println("done.");         }         {           if (bis != null) bis.close();           if (os != null) os.close();           if (sock!=null) sock.close();         }       }     }     {       if (servsock != null) servsock.close();     }   } } 

kindly me fix this!!!

try read file in such way on client side:

    socket s = servsock.accept();      inputstream in = s.getinputstream();     bufferedoutputstream bos = new bufferedoutputstream(new fileoutputstream("your_file"));      int c=0;     byte[] buff=new byte[2048];      while((c=in.read(buff))>0){ // read inputstream buffer         // if read          bos.write(buff, 0, c);     }      in.close();     bos.close(); 

do same on server side. inputstream file , output socket. robust way copy streams.
