Everything in Java binary format files is stored big-endian, MSB(Most Significant Byte) first. . This means if you use only Java, all files are done the same way on all platforms Mac, PC, Solaris, etc. The problem comes when you must exchange data files with some program not written in Java that uses little-endian order, most commonly C on the PC. Some platforms use big-endian order internally (Mac, IBM 390); some use little-endian order (Intel).

Hi,

I don't know whether it's possible in pure java, but it should be possible using native methods, just write some bytes into byte array from java and convert them to short or int at c side. If bytes are different, you will see the big/little endian difference.

21 questions remain open today, some date back to the year 2000.  I will close those I can today, and
request that Asker attend to the rest as quickly as possible.
