Classic ServerSocket Loop
class Server implements Runnable {
public void run() {
try {
ServerSocket ss = new ServerSocket(PORT);
while (!Thread.interrupted())
new Thread(new Handler(ss.accept())).start();
// or, single-threaded, or a thread pool
} catch (IOException ex) { /* ... */ }
}
static class Handler implements Runnable {
final Socket socket;
Handler(Socket s) { socket = s; }
public void run() {
try {
byte[] input = new byte[MAX_INPUT];
socket.getInputStream().read(input);
byte[] output = process(input);
socket.getOutputStream().write(output);
} catch (IOException ex) { /* ... */ }
}
private byte[] process(byte[] cmd) { /* ... */ }
}
}
Note: most exception handling elided from code examples
