Usage

From source file:NewFingerServer.java

public static void main(String[] arguments) throws Exception {
    ServerSocketChannel sockChannel = ServerSocketChannel.open();
    sockChannel.configureBlocking(false);

    InetSocketAddress server = new InetSocketAddress("localhost", 79);
    ServerSocket socket = sockChannel.socket();
    socket.bind(server);

    Selector selector = Selector.open();
    sockChannel.register(selector, SelectionKey.OP_ACCEPT);

    while (true) {
        selector.select();/*from ww w  .  j av  a  2s. c  o  m*/
        Set keys = selector.selectedKeys();
        Iterator it = keys.iterator();
