Java cross-platform
Hello. My name is Mary.
I have been assigned the task of writing an in-depth paper on "Why JAVA is
NOT cross-platform" for a Graduate course in Java programming (although its
still an intro to Java course).
I have found signifcant literature on how it IS cross-platform with the exception
of performance issues and licensing issues. What I am interested in is finding
out more about the technical modifications that must be made in the source
code for optimal performance on various platforms.
Any input? Thanks.

Re: Java cross-platform
The only place where you will find this to be an issue is probably on embeded
platforms. Not all API's will work on platforms with limited space - yet.
Check out the Sept 2001 issue of JDJ.

Re: Java cross-platform
Frankly, I wouldn't agree that having to make source code modifications
simply for performance reasons makes it "NOT cross-platform". But if you
can convince your prof that it does, then good for you.

I agree, cross-platform is a matter of whether or not it works on all platforms,
not how fast it runs.
But if thats what you are interested in, you might want to look into hardware
acceleration of graphics in Java. Under windows, some image classes(VolatileImage
or something like that i think?) is implemented using DirectX, while it uses
different code in other systems(i dont know very much about it but check
the information about Java SDK 1.4), so it might not run very well under
another operating system where Java doesnt use a native API. Also regarding
the Look&Feel system, you cant apply the Windows look and feel under a Mac(or
couldnt the last time i tried anyway), but thats hardly an issue.
Why are you writing an assignment about this, it sounds strange...
