Select the version we have just installed: There are 2 choices for the alternative javac (providing /usr/bin/javac).ġ /opt/jdk-16.0.1/bin/javac 1000 manual modeĪnd verify the result by running the same command: sudo update-alternatives -config javac Now repeat the drill for Java compiler: sudo update-alternatives -config javac There are 2 choices for the alternative java (providing /usr/bin/java).
