Well, that's the point really: you *can* run the same Java application
unmodified on multiple platforms, as long as it is written in 100% pure Java. This is
even a possibility for J3D, assuming in the future it too becomes 100% pure Java and
is based on top of JOGL.
Having a Java -> Native compiler is not as straightforward as a C compiler.
Java provides a lot of extra runtime flexibility over C/C++ which makes it nearly
useless
to compile it offline. Many of these decision branches must be resolved at runtime
which in turn influences the program execution path and optimization.

does not care but anuse class which ask more memory to manage. And of course slow
down CPU. I would like to know if depending on the OS (operation system)
performence are better or worse. But we must feep in mind that the tortul win at the
end
(La Fontaine). I am sure that improving the none creationos anuse mamorie class
JAVA could go much faster. I think that it is not san easy way. But it is the rigth
direction
to follow.
>So my question is why Sun does not create a compiler for the code. One compiler for
each OS. Because anyway we cannot export JAVA from one to another OS specialy
when we use J3D.
>It is just an idea. SUN should give the possibility of compiling any JAVA code for all
OS platform. We could send the rigth code to every OS. No need to do a quick
compiler on the user machine. Possibility of optimize the code from the begining and
not promote unuse clas and memory. There lto way in life be forward lor be backward.
in businnes it is much better to be forwward during war backward.
