How install java on mintos 2025

Java is one of the most widely used programming languages, powering applications from enterprise systems to mobile apps. If you’re using MintOS 2025, setting up Java is essential for running Java-based software, development tools, and application servers

Step 1: Update MintOS Package Index

Before installing any new software, it’s best to update the package index so your system uses the latest repository information:

sudo apt update && sudo apt upgrade -y

Step 2: Install the Default Java Runtime Environment (JRE)

The JRE is enough if you only need to run Java applications. MintOS 2025 provides it directly from the repositories:

sudo apt install default-jre -y

Check installation:

java -version

Step 3: Install the Java Development Kit (JDK)

If you plan to do development or need tools like Maven, Gradle, or application servers, install the JDK package:

sudo apt install default-jdk -y

Verify installation:

javac -version

Step 4: Set JAVA_HOME Environment Variable

Some applications require the JAVA_HOME variable to locate your Java installation. You can configure it in your shell profile:

echo "export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64" >> ~/.bashrc
echo "export PATH=\$JAVA_HOME/bin:\$PATH" >> ~/.bashrc
source ~/.bashrc

Confirm:

echo $JAVA_HOME

Step 5: Verify Java Installation

To ensure everything works correctly, run a simple check of your Java environment:

java -version
javac -version

If both commands return version details, Java is successfully installed and ready for use on MintOS 2025.
