Copies characters from this string into the destination byte array.

Usage

From source file:MainClass.java

public static void main(String args[]) throws Exception {
    byte buff[] = new byte[1024];
    InetAddress addr = InetAddress.getByName("www.java2s.com");
    Socket s = new Socket(addr, 80);

    OutputStream output = s.getOutputStream();
    InputStream input = s.getInputStream();
    String GetCmd = "GET /index.html HTTP/1.0\r\n\r\n";
    GetCmd.getBytes(0, GetCmd.length(), buff, 0);
    output.write(buff);/*www . j  ava  2  s  . c  o m*/
    input.read(buff, 0, buff.length);
    System.out.println(new String(buff, 0));

From source file:MulticastSender.java

public static void main(String[] args) {

    InetAddress ia = null;/* w  w w .  ja v a  2 s  .c  o  m*/
    int port = 0;
    String characters = "Here's some multicast data\n";
    byte[] data = new byte[characters.length()];

    // read the address from the command line
    try {
        try {
            ia = InetAddress.getByName(args[0]);
        } catch (UnknownHostException e) {
            //ia = InetAddressFactory.newInetAddress(args[0]);
        }
        port = Integer.parseInt(args[1]);
    } catch (Exception e) {
        System.err.println(e);
        System.err.println("Usage: java MulticastSender MulticastAddress port");
        System.exit(1);
    }

    characters.getBytes(0, characters.length(), data, 0);
    DatagramPacket dp = new DatagramPacket(data, data.length, ia, port);

    try {
        MulticastSocket ms = new MulticastSocket();
        ms.joinGroup(ia);
        for (int i = 1; i < 10; i++) {
            ms.send(dp, (byte) 1);
        }
        ms.leaveGroup(ia);
        ms.close();
    } catch (SocketException se) {
        System.err.println(se);
    } catch (IOException ie) {
        System.err.println(ie);
    }
