Thank you in advance

Answer 1

If you are using Ubuntu try this:

sudo apt install openjdk-12-jdk

Use the following command to verify the installed version of Java on your system.

java -version

If you are using Debian try this:

Create a new Apt configuration file /etc/apt/sources.list.d/java-13-debian.list, and edit in text editor.

sudo vim /etc/apt/sources.list.d/java-13-debian.list

and add following content in it.

deb http://ppa.launchpad.net/linuxuprising/java/ubuntu bionic main
deb-src http://ppa.launchpad.net/linuxuprising/java/ubuntu bionic main

Now import GPG key on your system for validating packages before installing them.

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EA8CACC073C3DB2A

Run the following commands to update apt-cache and then install Java 13 on the Debian system using the apt-get package manager.

sudo apt-get update
sudo apt-get install oracle-java13-installer

Use the following command to verify the installed version of Java on your system.

java -version
java version "13" 2019年09月17日
Java(TM) SE Runtime Environment (build 13+33)
Java HotSpot(TM) 64-Bit Server VM (build 13+33, mixed mode, sharing)

• Ingo: But on Debian/Raspbian (that's what the OP use) it will install version 13 and not version 12 as asked.

Answer 2

I'm using the BellSoft Liberica JDK's on Raspbian.

If you start from a fresh Raspbian you will have version 11

$ java -version
openjdk version "11.0.3" 2019年04月16日
OpenJDK Runtime Environment (build 11.0.3+7-post-Raspbian-5)
OpenJDK Server VM (build 11.0.3+7-post-Raspbian-5, mixed mode)

Easiest way to install:

• Visit https://bell-sw.com/
• Look for the version you want to use for "Linux ARM v7 & v8 32 bit HardFloat"
• Copy the link location to the deb-file
• Run the following script (is for the version 12.0.2 you are looking for)
• Check if the version installed correctly by running "java -version" again

$ cd /home/pi

$ wget https://download.bell-sw.com/java/12.0.2/bellsoft-jdk12.0.2-linux-arm32-vfp-hflt.deb

$ sudo apt-get install ./bellsoft-jdk12.0.2-linux-arm32-vfp-hflt.deb

$ sudo update-alternatives --config javac

$ sudo update-alternatives --config java

• Ingo: You downloaded bellsoft-jdk12.0.2-linux-arm32-vfp-hflt.deb (jdk12) and installed bellsoft-jdk13-linux-arm32-vfp-hflt.deb (jdk13)? Really?
• Frank: Sorry @Ingo my mistake, copy/paste and only half adapted ;-) Fixed now!
