java compiler?

[gerrymcc]

I know that javac compiles to bytecode, what does a typical C++
compile to? I'm guessing it's some sort of native machine code, so
there's no need for something like a java runtime environment. Can
Java be compiled like that? I'm wondering because if I wanted to
distribute software I'd written, I'd like it to be in a form where the
user just has to click on icon to launch the program.
Thanks for any help,
Gerard

Compiling Java to machine-code is a common thread in this
newsgroup, so a searh on google or a simple scroll-back
in the thread-list should be enough to find answers.

A simple double-click on a jar-file can start the application
as well if there is a JRE installed on the system and the jar-
file contains informations about the class to be executed
when double-clicked.

Native compilation with Java is possible, but comes at a price: <>.

Have your user install a JRE like any other plug-in. Then create an
executable JAR from your program and the user will be able to start it
by double-clicking on the corresponding icon.

That should have been
<http://www.geocities.com/marcoschmidt.geo/jcomp.html>. The part on
native compilers.

C++ compiles to object code, which is very similar to a machine code
image of each method. It then has to be glued together into an EXE
file by a linker.

You can create exe files (which are then NOT platform independent
anymore) with Java too. See

Try GCC - it contains GCJ that makes native code out of .java/.class files.
