  Description     : manages multiple Java installations

jenv is a tool to support mutliple Java installations. It is useful for
developers who need to work with multiple Java versions. Although Debian
already provides the update-alternatives mechanism for maintaining
multiple Java versions, jenv has the advantage that you can specify a
different default Java version on a directory-by-directory basis, useful
when developing multiple projects, some of which only work on Java 11,
others only on Java 8, and then running java/javac/etc from that
directory (or its subdirectories) will automatically invoke the
appropriate version for that project.
