Convert byte array to integer
<p>I have a byte array, I want to convert them to integer.
How to do it?
My code as below:</p>

<pre><code>byte[] bytes = new byte[]{(byte)0xFF, (byte)0x01, (byte)0x0F, ...};
int[] integers = new int[bytes.length];
int i;
for(i = 0; i &lt; bytes.length; i++) {
integers[i] = bytes[i];
}
</code></pre>

<p>Get to integers array as {-1, 1, 15, ...}.
But I want to get is {255, 1, 15, ...}.
Any function can arrived it?</p>
