e165.
Setting the Byte Ordering for a ByteBuffer</h3>
By default, the byte ordering for a <code>ByteBuffer</code> is
<code>ByteOrder.BIG_ENDIAN</code>. This means that if you put a multibyte
value into the buffer, the most significant byte is written out first.
With <code>LITTLE_ENDIAN</code>, the least significant byte is
written out first.
<pre>
// Obtain a ByteBuffer; see also <a href="../java.nio/CreateBuf.html" class="eglink"><font size="-1"><b>e158</b> Creating a ByteBuffer</font></a>
ByteBuffer buf = ByteBuffer.allocate(<font color="#0066ff"><i>10</i></font>);
// Get default byte ordering
ByteOrder order = buf.order(); // ByteOrder.BIG_ENDIAN
// Put a multibyte value
buf.putShort(0, <font color="#0066ff"><i>(short)123</i></font>);
buf.get(0); // 0
buf.get(1); // 123
// Set to little endian
buf.order(ByteOrder.LITTLE_ENDIAN);
// Put a multibyte value
buf.putShort(0, <font color="#0066ff"><i>(short)123</i></font>);
buf.get(0); // 123
buf.get(1); // 0
