Returns the byte array which this buffer is based on, if there is one.

Usage

From source file:Main.java

public static void main(String args[]) throws IOException {
    FileInputStream fis = new FileInputStream("FileChannelExample.java");
    FileChannel fc = fis.getChannel();

    ByteBuffer bb = ByteBuffer.allocate((int) fc.size());

    fc.read(bb);/*from   w w  w.  j  a v  a  2 s  .c  o m*/
    bb.flip();

    String fileContent = new String(bb.array());

    fc.close();
    fc = null;

    System.out.println("fileContent = " + fileContent);
}

From source file:Test.java

public static void main(String[] args) throws Exception {

    AsynchronousSocketChannel client = AsynchronousSocketChannel.open();
    InetSocketAddress address = new InetSocketAddress("localhost", 5000);

    Future<Void> future = client.connect(address);
    System.out.println("Client: Waiting for the connection to complete");
    future.get();//from ww w  . ja v  a  2  s .co m

    String message = "";
    while (!message.equals("quit")) {
        System.out.print("Enter a message: ");
        Scanner scanner = new Scanner(System.in);
        message = scanner.nextLine();
        System.out.println("Client: Sending ...");
        ByteBuffer buffer = ByteBuffer.wrap(message.getBytes());
        System.out.println("Client: Message sent: " + new String(buffer.array()));
        client.write(buffer);
    }
}
