How do I install Java 14 on Ubuntu Linux?

For reference, I have successfully installed Pop for OpenJDK 11 by default! It was successfully installed on _ OS 19.10.

Here, we will use the Java 14 installer for Linux Uprising (originally based on the WebUpd 8 Java package).

Simply enter the following command in the terminal to install:

sudo add-apt-repository ppa:linuxuprising/java
sudo apt update
sudo apt install oracle-java14-installer

This should be done. If you want to set it as the default, you can enter the following command:

sudo apt install oracle-java14-set-default

It is worth noting that this only applies to Ubuntu-based distributions. If you want to install it on Debian and other Linux distributions, you can also install Java 14 according to the detailed guidelines in Linux Uprising.

Summarize

Of course, these will bring the latest features. If you don't want to break the original environment, you may want to continue to use Java 11. If you want to experiment with an understanding of the risks, keep trying!
