How to install JDK 17 on Ubuntu!

Introduction

JDK 17 has been released recently, so I decided to tell you how to install it on Ubuntu. Fun fact, my first ever post was "How to install JDK 16 on Ubuntu!" Let's get started.

Installation

Option 1

There are 2 ways you can install JDK 17, let's do the first option. Since Java OpenJDK 17 is an open-source implementation of the Java SE platform. Since the OpenJDK versions available in the default repositories are not up to date, we will have to download the Open-source JDK 17 using the wget command.

wget https://download.java.net/java/GA/jdk17.0.2/dfd4a8d0985749f896bed50d7138ee7f/8/GPL/openjdk-17.0.2_linux-x64_bin.tar.gz

Extract the downloaded tarball.

tar xvf openjdk-17.0.2_linux-x64_bin.tar.gz

Then move the extracted file to the /opt/ directory as shown.

sudo mv jdk-17.0.2/ /opt/jdk-17/

Then we need to set the environment variables.

echo 'export JAVA_HOME=/opt/jdk-17' | tee -a ~/.bashrc
echo 'export PATH=$PATH:$JAVA_HOME/bin '|tee -a ~/.bashrc
source ~/.bashrc

Verify the Java installation as below.

echo $JAVA_HOME
/opt/jdk-17

Check the installed version of Java.

java --version
openjdk 17.0.2 2022-01-18
OpenJDK Runtime Environment (build 17.0.2+8-86)
OpenJDK 64-Bit Server VM (build 17.0.2+8-86, mixed mode, sharing)

Option 2

For this option, we download the production-ready Java from the Java SE Downloads page. Alternatively, one can install Oracle JDK 17 on Ubuntu 20.04/18.04 using the “Linux Uprising” team PPA installer script which automatically downloads and sets the default Java version on Ubuntu 64-bit based systems. First, we need to add the PPA as below.

sudo add-apt-repository ppa:linuxuprising/java

Then install Oracle JDK 17 as shown.
