Tank you Christopher,

I know "jdk" that I use regularly, but I am looking for something different.
The development with JDK produce .jar files that are compressed files made with byte-code (.files.class ).
...To run jar files, you need the java environment (the command is "java -jar xxx.jar").

I look for a possibility to get directly executable files in Linux environment.
They are some tools that convert jar filer in executable for the Windows environment.. (Launch4j, Excelsior <very expensive!!>, ...).

I am looking for a a real compiler in Linux environment for the Java language, a compiler that produce directly executable files (as gcc is for the C language)...

That's a very old version of the Fedora docs. I'm pretty sure gcj is a
dead project. Fedora now ships with OpenJDK. In the latest version
(Fedora 29), there are several versions available. To see them, run:
sudo dnf repoquery --whatprovides \*/bin/javac

You'll probably want either JDK 8 or 11, so one of the following
should work for you:
sudo dnf install java-1.8.0-openjdk-devel # if you want JDK 8, specifically
sudo dnf install java-11-openjdk-devel # if you want JDK 11, specifically
sudo dnf install java-openjdk-devel # if you want the latest OpenJDK,
currently 11
