Oracle Java is a popular programming language and platform for creating and running a variety of applications. If you are using Debian and need to install Oracle Java 17 on Debian, this article will walk you through the installation process step by step. Please keep in mind that Oracle Java must be installed manually on Debian because it is not accessible in the official Debian repositories. In this article, I’ll show you How to Install Oracle Java 17 on Debian step by step procedures.

Prerequisites

  • You should have a Debian 11(Bullseye) system up and running.
  • To run root commands, you must have sudo or root access.

Step 1: Initial Setup

Make sure your system or server packages are updated to the latest version available.

sudo apt update sudo apt upgrade -y

Step 2: Search for Java 17 Package

You can search your Debian 11 system to find if Java 17 packages are available in the system repositories.

Execute the below command to search for Java 17.

sudo apt-cache search openjdk | grep 17

If you get the below output you, you are having JRE and JDK repositories available in your Debian system.

openjdk-17-dbg – Java runtime based on OpenJDK (debugging symbols) openjdk-17-demo – Java runtime based on OpenJDK (demos and examples) openjdk-17-doc – OpenJDK Development Kit (JDK) documentation openjdk-17-jdk – OpenJDK Development Kit (JDK) openjdk-17-jdk-headless – OpenJDK Development Kit (JDK) (headless) openjdk-17-jre – OpenJDK Java runtime, using Hotspot JIT openjdk-17-jre-headless – OpenJDK Java runtime, using Hotspot JIT (headless) openjdk-17-jre-zero – Alternative JVM for OpenJDK, using Zero openjdk-17-source – OpenJDK Development Kit (JDK) source files

Step 3: Install Java 17

You can also install JDK using the below command.

sudo apt install openjdk-17-jdk

Once the installation is complete, you should have Java 17 installed on your Debian 11.

Step 4: Verify Java 17 Installation

Verify the installation using the below command

java -version

You will receive an output similar to the one below.

openjdk 17.0.7 2023-04-18 OpenJDK Runtime Environment (build 17.0.7+7-Debian-1deb11u1) OpenJDK 64-Bit Server VM (build 17.0.7+7-Debian-1deb11u1, mixed mode, sharing)

Step 5: Configure Environment Variables

To set the Java environment variables, you need add the following lines to your profile to export Java path.

Execute the below command to create a new file in your profile.d directory or to your bashrc file, so that each time you open your terminal this file runs.

Now we will add the Path to the profile.

cat <<EOF | sudo tee /etc/profile.d/jdk.sh export JAVA_HOME=/usr/lib/jvm/jdk-17/ export PATH=$PATH:$JAVA_HOME/bin EOF echo ‘export JAVA_HOME=/usr/local/jdk-17’ >> ~/.bashrc echo ‘export PATH=$JAVA_HOME/bin:$PATH’ >> ~/.bashrc

These commands will append the export lines to the end of the.bashrc file.

To implement the changes instantly, you must source the.bashrc file. Execute this command:

source ~/.bashrc

The environment variables in your current terminal session will be modified when you source the file. If you do not wish to source it right now, the modifications will be applied the next time you launch a new terminal session.

Step 6: Validate Java Path

Run the following command to validate the JAVA_HOME environment variable:

echo $JAVA_HOME
