Use java -version to verify openjdk installation
java -version openjdk version "11.0.4" 2019-07-16 OpenJDK Runtime Environment (build 11.0.4+7) OpenJDK 64-Bit Server VM (build 11.0.4+7, mixed mode)
Install openjdk 12 manually
The first step is downloading the openjdk binary archive file. The official openjdk website is https://jdk.java.net and you can download the openjdk version you are looking for from https://jdk.java.net/archive/.
To download openjdk 12 binary archive file in arch you can use following command. Download it in a place you are going to extract it. For manual installation of an application in linux, linux admins use mostly /opt folder. However you root access for any write access. That means you need run linux command as sudo user.
Make sure you have wget cli tool installed, if not you can use sudo pacman -S wget to install it
$ cd /opt $ sudo mkdir java $ cd java $ sudo wget https://download.java.net/java/GA/jdk12/33/GPL/openjdk-12_linux-x64_bin.tar.gz
After downloading the .tar.gz archive file, you can use tar -xfv to extract it in /opt
sudo tar -xvf openjdk-12_linux-x64_bin.tar.gz
After extracting I recommend use jEnv to set JAVA_HOME and PATH variables. Refer to Switching JDKs using jEnv for more information
