ShortBuffer shortBuff = ShortBuffer.allocate(capacity);

    shortBuff.put((short) 565);

    shortBuff.flip();

    System.out.println("Limit of short buffer : "

                                  + shortBuff.limit());

    System.out.println("capacity of short buffer : " 

                              + shortBuff.capacity());

    while (shortBuff.hasRemaining()) 

      {
