How can I detect endianness on a system

Question

How can I detect endianness on a system in java?I dont want to use inbuilt methods as its a interview question. Also how to convert big to small and vice versa?

Am looking for ans using Java and not C/C++. I had found such links Detecting endianness programmatically in a C++ program

If an interviewer wants you to program in Java without using any inbuilt methods then you probably want to call them on that. :) — Chris, Dec 02 '11 at 17:39
If for a minute I put aside that it's just a silly interview question, why would anyone want to know the endianness in Java? It isn't ever going to matter, is it? — harold, Dec 02 '11 at 17:57

Doesn't java.nio.ByteOrder.nativeOrder() give it to you?

Check the source of that.

That method eventually does something dirty with Unsafe. Which is build-in. If there's any way around using that, it's magic. – harold Dec 02 '11 at 18:24
