Little/Big Endian

Question

How can I determine if the OS is little/big endian in Java?

Why do you want to do this? Java doesn't care and if you're calling native code can't you use that to figure out what architecture you're on? — Amok, Aug 31 '09 at 18:19

@Zed: I think that question is different. It is asking if the VM itself uses big- or little-endian representation internally, not necessarily how to detect what the OS is using. — erickson, Aug 31 '09 at 18:52

Check whether java.nio.ByteOrder.nativeOrder() is equal to ByteOrder.LITTLE_ENDIAN or ByteOrder.BIG_ENDIAN.

Much like erickson, +1 - both for the correct answer, and the gumption :) – aperkins Aug 31 '09 at 19:51
