The installation of java is complete, with configuration issues
remaining.
You must use update-alternatives for java and javac.
$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac
What you have to enter is the previous number (2 in the table above),
not the back number.
Maybe even 2 in javac.
And put the following in your .bash_profile.
JAVA_HOME=$(readlink -f /usr/bin/javac | sed "s:/bin/javac::")
export JAVA_HOME
Then, execute as follows
$ source ~/.bash_profile
After this , by
$ echo $JAVA_HOME
###############
wolfgang@Fuji:~$ echo $JAVA_HOME
/usr/lib/jvm/java-11-openjdk-amd64
in my .bash_profile is:
JAVA_HOME=$(readlink -f /usr/bin/javac | sed "s:/bin/javac::")
export JAVA_HOME
#############
Confirm that it returns following
/usr/lib64/jvm/java-1.8.0-openjdk-1.8.0
This completes the JAVA setup.
Regards.
