As mentioned below, class files are MSB. That is defined in the Java
specification. For serialized objects, one only has to look at the
serialization source code. The specification also indicates that a VM's
internal representation is implementation dependent. The common sense of

Okay, I did a grep on the VMSpec docs and found out:

You are looking in the *wrong* place , try these two excellent books on the
Java Virtual machines,
1.) "The Java Virtual Machine by Jon Meyer and Troy Downing (Publisher
O'Reilly)"
2.) "Inside the Java Virtual Machine by Bill Venners ( publisher McGraw - Hill
)

Class files and serialized objects are MSB. The endianness of the VM
itself is implementation dependent; however, if you could devise a
pure-Java program th

It can't be done, so you *have* to do it using native code (JNI). Sorry,
but that's the way it is.

You can deal with endianess in native code not in Java
code. I think that system dependent stuffs should not be
dealt with in Java code.

You won't...not from java at least. How you determine endianess will be
platform-dependant. In glibc (and possibly libc5) systems, look at
/usr/include/endian.h (you'll have to have native code for this). This
will be different on other systems (for example, Solaris).

Dear all,
I would like to ask about a question. I am doing a JAVA program
which should deal with system architeucture. I would like to ask a
question how can I know the system is little endian or big endian?
Thanks!
