Document

Writes all the remaining bytes of the src byte buffer to this buffer's current position, and increases both buffers' position by the number of bytes copied.

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    SocketChannel sChannel = SocketChannel.open();
    sChannel.configureBlocking(false);/*from w  w w  .  j  a v a2  s . c  o  m*/
    sChannel.connect(new InetSocketAddress("hostName", 12345));

    ByteBuffer buf = ByteBuffer.allocateDirect(1024);
    buf.put((byte) 0xFF);

    buf.flip();

    int numBytesWritten = sChannel.write(buf);
}

From source file:MainClass.java

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

    bb.put((byte) 0x12);
    bb.put((byte) 0x13);
