Change JAVA_HOME value in Linux Mint 19x

Question

I have a linux mint 19x and if I do:

echo $JAVA_HOME >> /usr/lib/jvm/java-8-oracle

I want to change the path to put Java 11, but not in the .bashrc, .profile, /etc/enviroment file, I see my JAVA_HOME defined

I tried to put the JAVA_HOME path in my /etc/environment

JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"

Can someone tell me where my JAVA_HOME can be defined, so I can change it well.

Via the command line, you can simply change your JAVA_HOME variable path:

export JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"

Then redefine the current path prefixing the jdk binaries:

export PATH=$JAVA_HOME/bin:$PATH

NB: This will only take effect within the current terminal session.

Another great option is to use SDKMan to manage SDKs like Java and so on.

I use all the time on all my Linux machines and it's very easy to switch between Java version.

You can find the link here:

Firstly, check what JDKs you have installed :

sudo update-alternatives --config java
   # And select the usr/lib/jvm/java-11-openjdk-amd64/bin/java version.
   # Also, set the JAVA_HOME variable for Maven to pick the correct JDK:

Then :

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
