Converts the double argument to a long using the doubleToLongBits method in class Double, and then writes that long value to the underlying output stream as an 8-byte quantity, high byte first.

Usage

From source file:SquareClient.java

public static void main(String args[]) throws Exception {
    String server = args[0];/*from w  w w .j  a  va2s . c om*/
    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();
}
