public class SocketClient {
    private final static Logger logger = Logger.getLogger(SocketClient.class);
    private static class inner {
        private static SocketClient sc = new SocketClient();
    }

    private SocketClient() {
    }

    public static SocketClient getSocketClient() {
        return inner.sc;
    }
}
