Convert byte array to an integer/long/double

[TheObserver]

I have a byte array I'm reading in from a file. I need to be able to take n bytes from that array and convert them into an integer/long/double, such that the resultant value is equal to the four bytes.

For example, if I have these values in my byte array:
10100111
00001010
11100110
10001010

I would like to read them like this:
10100111000010101110011010001010

And produce the value:
2802509450

Thanks for your time.

You should post in the general Java forum. This one uses to be just for J2EE questions.

If you post the way you're reading the file, it'd be useful too.

Cheers,
