This guide is intended to get you up and running with this tool quickly with the most common settings. For a thorough review of all options, refer to the official documentation.
Java is a high-level, object-oriented programming language first released by Sun Microsystems in 1995.
It is designed to have as few implementation dependencies as possible, making it a versatile and widely-used language.
Yes, there are numerous ways to install Java on Arm Linux distributions.
Below are some of the common methods to install Java. This includes both the Java runtime environment (JRE), which is used to run Java applications and the Java development kit (JDK) which is used to create Java applications.
Pick the one that works best for you.
For distributions using apt - including Debian and Ubuntu:
sudo apt update
sudo apt install default-jre -y
sudo apt install default-jdk -y
For distributions using dnf - including Fedora and Red Hat:
sudo dnf install java-latest-openjdk
For distributions using pacman - including Arch and Manjaro:
sudo pacman -S jdk-openjdk
sudo pacman -S jre-openjdk
Amazon Corretto is a no-cost distribution of the Open Java Development Kit (OpenJDK). It is maintained and supported by Amazon Web Services (AWS).
You can install Corretto using apt with the commands:
wget -O - https://apt.corretto.aws/corretto.key | sudo gpg --dearmor -o /usr/share/keyrings/corretto-keyring.gpg && \
echo "deb [signed-by=/usr/share/keyrings/corretto-keyring.gpg] https://apt.corretto.aws stable main" | sudo tee /etc/apt/sources.list.d/corretto.list
sudo apt-get update; sudo apt-get install -y java-21-amazon-corretto-jdk
More installation options for Corretto are available in the Amazon Corretto 21 Guide for Linux
For Linux distributions with snap you can install Java using:
sudo snap install openjdk
You can download Java from the Oracle website and install it manually. Look for the files with ARM64 in the description.
Download a tar.gz file from the website.
Extract the contents of the file:
tar xvf jdk-22_linux-aarch64_bin.tar.gz
Move the contents to a directory of your choice:
sudo mv jdk-22.0.2 /usr/local/
Set up environment variables to locate your installation:
export JAVA_HOME=/usr/local/jdk-22.0.2
export PATH=$JAVA_HOME/bin:$PATH
Add the environment variables to your ~/.bashrc file to set them permanently.
Yes, you can change the default version. For systems with apt use:
sudo update-alternatives --config java
You will be given the option to select a new version. The options are depend on the software currently installed on your computer.
There are 3 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/lib/jvm/java-21-amazon-corretto/bin/java 12100004 auto mode
1 /usr/lib/jvm/java-17-openjdk-arm64/bin/java 1711 manual mode
2 /usr/lib/jvm/java-21-amazon-corretto/bin/java 12100004 manual mode
3 /usr/lib/jvm/java-21-openjdk-arm64/bin/java 2111 manual mode
Press <enter> to keep the current choice[*], or type selection number:
For this case, if you select option 1, Java 17 becomes the default.
Print the version of the Java runtime:
java -version
The output will be similar to:
openjdk version "21.0.4" 2024-07-16
OpenJDK Runtime Environment (build 21.0.4+7-Ubuntu-1ubuntu224.04)
OpenJDK 64-Bit Server VM (build 21.0.4+7-Ubuntu-1ubuntu224.04, mixed mode, sharing)
Print the version of the Java compiler:
javac -version
The output will be similar to:
javac 21.0.4
It’s important to ensure that your version of Java is at least 11.0.9. There are large performance improvements starting from version 11.0.9. Since then, Java performance has steadily increased over time and newer versions will provide better performance.
The Java virtual machine (JVM) includes a number of flags which are available to tune performance and aid in debugging. Some of the flags are general purpose and some are Arm architecture specific.
To print the final values of the flags after the JVM has been initialized run:
java -XX:+PrintFlagsFinal -version
There are a number of Java related tools you may want to install.
Apache Maven is a powerful build automation tool primarily used for Java projects.
It simplifies the build process by providing a uniform build system, dependency management, and project management capabilities.
You can install it from the apt package manager:
sudo apt-get install -y maven
Print the version:
mvn -v
The output is similar to:
Apache Maven 3.8.7
Maven home: /usr/share/maven

Default locale: en, platform encoding: UTF-8
OS name: "linux", version: "6.8.0-41-generic", arch: "aarch64", family: "unix"
Gradle is another build automation tool that is widely used for Java projects.
It is designed to be highly customizable and flexible, making it suitable for a wide range of projects.
You can install it from the apt package manager:
sudo apt install gradle -y
You can also install specific versions by downloading and extracting a zip file:
wget https://services.gradle.org/distributions/gradle-8.10-bin.zip -O gradle-8.10-bin.zip
unzip gradle-8.10-bin.zip
sudo mv gradle-8.10 /opt/gradle
sudo ln -s /opt/gradle/bin/gradle /usr/local/bin/gradle
Print the version:
gradle -v
The output is similar to:
Welcome to Gradle 8.10!
Here are the highlights of this release:
- Support for Java 23
