Encodes this String into a sequence of bytes using the platform's default charset, storing the result into a new byte array.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    DatagramChannel server = DatagramChannel.open();
    server.bind(null);/* w  ww .  j a va2  s  . co m*/
    NetworkInterface interf = NetworkInterface.getByName(MULTICAST_INTERFACE_NAME);
    server.setOption(StandardSocketOptions.IP_MULTICAST_IF, interf);

    String msg = "Hello!";
    ByteBuffer buffer = ByteBuffer.wrap(msg.getBytes());
    InetSocketAddress group = new InetSocketAddress(MULTICAST_IP, MULTICAST_PORT);

    server.send(buffer, group);
    System.out.println("Sent the   multicast  message: " + msg);
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    String strFilePath = "C://demo.txt";
    FileOutputStream fos = new FileOutputStream(strFilePath);
    String strContent = "Write File using Java FileOutputStream example !";
    fos.write(strContent.getBytes());
    fos.close();/*from  w ww .  java2s . co m*/
}
