Sending files over network in Java

Client Code

import java.io.BufferedOutputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.net.Socket;

public class Client {

public static void main (String [] args ) throws IOException {

    int filesize=1022386;

    int currentTot = 0;

    Socket socket = new Socket("127.0.0.1",15123);
    byte [] bytearray = new byte [filesize]; 
    InputStream is = socket.getInputStream();

    FileOutputStream fos = new FileOutputStream("UNNK2125.jpg");
    BufferedOutputStream bos = new BufferedOutputStream(fos);
    bytesRead = is.read(bytearray,0,bytearray.length);      
    currentTot = bytesRead;

    do { 
        bytesRead = is.read(bytearray, currentTot, (bytearray.length-currentTot));

        if(bytesRead >= 0)
            currentTot += bytesRead;

    } while(bytesRead > -1);

    bos.write(bytearray, 0 , currentTot);
    bos.flush();

}

Server Code

import java.io.IOException; import java.io.OutputStream; import java.net.ServerSocket; import java.net.Socket;

import java.io.*; public class Server {

public static void main (String [] args ) throws IOException {

    ServerSocket serverSocket = new ServerSocket(15123);

    System.out.println("Accepted connection : " + socket);

    File transferFile = new File ("./resources/UNNK2125.jpg");
    byte [] bytearray = new byte [(int)transferFile.length()];

    FileInputStream fin = new FileInputStream(transferFile);
    BufferedInputStream bin = new BufferedInputStream(fin);
    bin.read(bytearray,0,bytearray.length);

    OutputStream os = socket.getOutputStream(); 
    System.out.println("Sending Files..."); 

    os.write(bytearray,0,bytearray.length);
    os.flush();

    bin.close();
    socket.close();
    serverSocket.close();

    System.out.println("File transfer complete"); 
}
