Usage

From source file:SquareClient.java

public static void main(String args[]) throws Exception {
    String server = args[0];//w w  w.  ja  v  a2  s.  com
    int port = Integer.parseInt(args[1]);
    double value = Double.valueOf(args[2]).doubleValue();

    Socket s = new Socket(server, port);
    OutputStream os = s.getOutputStream();
    DataOutputStream dos = new DataOutputStream(os);
    dos.writeDouble(value);

    InputStream is = s.getInputStream();
    DataInputStream dis = new DataInputStream(is);
    value = dis.readDouble();

    System.out.println(value);
    s.close();
}
