How to install Java 13 on Ubuntu 18.04 and newer? (Tested onUbuntu 22.04 with Java 21 also)

Question

How to install Java 13 on Ubuntu 18.04.3 from terminal with sudo privildges?

Answer 1

Method 2 For newer Ubuntu (tested in 2025 with Ubuntu 22.04):

 sudo apt update
 sudo apt upgrade -y
 apt search openjdk
 #select a version like openjdk-21-jdk or headless if server
 # notice the jdk and not jre if you want to compile & build
 # headless for jdk without UI non GUi programs; server side, batch, terminal only
 sudo apt install openjdk-21-jdk-headless -y

Remove the -y if you want to be prompted

this lists till jdk 21, for newer ones need to use method 1 for now

Method 1: Followed https://openjdk.java.net/install/index.html per Pilot6 comment (thanks).

JDk 22 and later : https://jdk.java.net/23/

JDK 9 to 21

Oracle's OpenJDK JDK binaries for Windows, macOS, and Linux are available on release-specific pages of jdk.java.net as .tar.gz or .zip archives.

As an example, the archives for JDK 13 may be found on jdk.java.net/13 and may be extracted on the command line using

$ tar xvf openjdk-13*_bin.tar.gz

Commands to download java 15 from jdk net (Linux / x64) using terminal and saving to a folder in Downloads folder called 'j'. ~ is shortcut for current logged in user's home directory

mkdir ~/Downloads/j
cd  ~/Downloads/j
curl https://download.java.net/java/GA/jdk15.0.2/0d1cfde4252546c6931946de8db48ee2/7/GPL/openjdk-15.0.2_linux-x64_bin.tar.gz --output ./jdk_15.0.2_linuxx64bin.tar.gz
 tar xvf j16.tar.gz

Used sudo mv to move directory 'jdk-13.0.1' to /usr/lib/jvm/

  sudo mv jdk-13  /usr/lib/jvm/

Then in my ~/.profile file added/edited (as I had Java 11 before) in text editor:

export JAVA_HOME=/usr/lib/jvm/jdk-13.0.1
export PATH=$JAVA_HOME/bin:$PATH

In the current terminal(s) to reload the profile after changes gave command:

. ~/.profile 

Note that its a period, a space and then the file name. Its short hand for the command:

source ~/.profile

and could use Java 13. Worked after restart too, without running the commands, due to entry in ~/.profile

To test, in terminal give command : echo $JAVA_HOME Will see out put :

/usr/lib/jvm/jdk-13.0.1

You can also set it up as alternatives as in https://askubuntu.com/a/464894/165511 I like to set up the JAVA_HOME variable as need that to run maven etc

sudo update-alternatives --config java
sudo update-alternatives --config javac

Also run

java -version

and

javac -version

To check version of java that is used in that terminal. remember ytou can have different versions in different scripts and programs
