You need 3 classes. Receiver, RemoteThread and Sender. These classes are not tested by me
//these classes are on the clientside
public class Receiver{//listens to connections
ServerSocket serverSocket = new ServerSocket(port);
while (...){
Socket client=serverSocket.accept();//waits for new connection
RemoteThread thread=new RemoteThread(client);
thread.start();
serverSocket.close();
public class RemoteThread{
final static int BUSYWAITTIME=10;//10 ms
Socket socket;
public RemoteThread(Socket _socket) {
this.socket = _socket;
public void run() {
BufferedOutputStream out = new java.io.BufferedOutputStream(socket.getOutputStream(),socket.getSendBufferSize());
int inBuffSize=socket.getReceiveBufferSize();
BufferedInputStream in = new java.io.BufferedInputStream(socket.getInputStream(),inBuffSize);//wait until get enuff
byte[] buff=new byte[inBuffSize];
while (...) {
//read
while(in.available()<=0 && !stopped){//just wait for it to become ready
try{wait(BUSYWAITTIME);}catch(InterruptedException e){}
int readBytes=in.read(buff);
//do something with the bytes in buff
//This class is on the clientside
public class Sender{
Socket socket = new Socket(host, port);//connects to server
OutputStream out = socket.getOutputStream();
PrintWriter outPrinter=new PrintWriter(out,true);
InputStream in = socket.getInputStream();
//use out or outPrinter to write to server
