4.6 (How) Does Debian support Java?
Since the official Java Development kit and Runtime Environment from Sun
Microsystems is non-free software, even undistributeable by Debian, it cannot
properly be included in Debian. If you want those installed anyway, please
refer to the
java-package package in contrib.
However, both the JDK and several free implementations of Java
technology are available as Debian packages. You can write, debug and run Java
programs using Debian.
Running a Java applet requires a web browser with the capability to recognize
and execute them. Several web browsers available in Debian, such as Mozilla or
Konqueror, support Java plug-ins that enable running Java applets within them.
Netscape Navigator, while non-free, is also available as a Debian package and
it can run Java applets.
Please refer to the
FAQ for more information.
