Adding new JRE/JDK ubuntu

This command helps you to add an alternative JDK/JRE a like Azul/Zulu or adoptopenjdk.

After extract your JDK/JRE usually we extract on "/usr/lib/jvm" debian/ubuntu systems.

We will need 3 commands if we are adding a JDK.

To Set directly

sudo update-alternatives — set java <Directory where JAVA has been extracted>/bin/java
sudo update-alternatives — set javac <Directory where JAVA has been extracted>/bin/ javac
sudo update-alternatives — set javaws <Directory where JAVA has been extracted>/bin/javaws
Enter fullscreen mode Exit fullscreen mode

To install as new option

sudo update-alternatives — install “/usr/bin/java” “java” “<Directory where JAVA has been extracted>/bin/java” 1
sudo update-alternatives — install “/usr/bin/javac” “javac” “<Directory where JAVA has been extracted>/bin/javac” 1
sudo update-alternatives — install “/usr/bin/javaws” “javaws” “<Directory where JAVA has been extracted>/bin/javaws” 1

Enter fullscreen mode Exit fullscreen mode

And to select a new one

sudo update-alternatives — config java
Enter fullscreen mode Exit fullscreen mode
