  public static void main(String[] args) {
    LongBuffer longBuf = LongBuffer.allocate(256);
    longBuf.put(345678);
    longBuf.put(8765433);
    longBuf.put(643564);
    longBuf.flip();
    System.out.println("Content in long buffer.");
    while (longBuf.hasRemaining()) {
      System.out.println(longBuf.get());
