The “Linux Uprising” team ppa has made the installer script, which automatically downloads and installs Oracle JDK 16 package, and sets Java 16 as the default Java version (setting JAVA_HOME, etc.) on 64-bit Ubuntu based system.
1.) Open terminal and run command to add the PPA:
sudo add-apt-repository ppa:linuxuprising/java
Type user password (no asterisk feedback) when it asks and hit Enter to continue.
2.) After adding PPA, refresh system package cache and install the script:
sudo apt update sudo apt install oracle-java16-installer
If you don’t want to set Java 16 as default, replace the last command with:
sudo apt install oracle-java16-installer --no-install-recommends
Once the package is installed, you have to accept the license (press Tab to highlight) before starting the download process.
And after installed Oracle Java 16, check via java --version command:
(Optional) To uninstall the PPA repository, run command in terminal:
sudo add-apt-repository --remove ppa:linuxuprising/java
And remove Oracle Java 16 if you want by running command:
sudo apt-get remove oracle-java16-installer
