Little Endian and Big Endian

Endianness: is the ordering of individually addressable
sub-units (words, bytes, or even bits) within a longer data
word stored in external memory.
for example, the byte-order


Little Endian and Big Endian

In JNI, if the type is specified using java type, for example,
int a;
Then in JNI, we don't need to convert to little endian for Linux,
only those data in raw byte array, if we need convert them to same
data structure, for those int, short, long... , we need convert
them to local host format( linux is little endian, solaris is big endian)
