Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    ServerSocket serverSocket = new ServerSocket(12900, 100, InetAddress.getByName("localhost"));
    System.out.println("Server started  at:  " + serverSocket);

    while (true) {
        System.out.println("Waiting for a  connection...");

        final Socket activeSocket = serverSocket.accept();

        System.out.println("Received a  connection from  " + activeSocket);
        Runnable runnable = () -> handleClientRequest(activeSocket);
        new Thread(runnable).start(); // start a new thread
    }//from w ww.ja  v  a 2  s  .  c  om
}
