Knowing how to install Java in Ubuntu is an essential skill for developers, system administrators, and businesses running Java-based applications. Whether you’re deploying enterprise software, hosting Minecraft servers, running Jenkins, or building Spring Boot applications, Java remains one of the world’s most widely used programming platforms.
Modern Ubuntu servers provide an excellent environment for Java because they are secure, stable, lightweight, and highly scalable. Combined with enterprise-grade VPS hosting from India, Ubuntu delivers outstanding performance for developers serving users across Asia and worldwide. If you’re planning to install Java in Ubuntu, understanding the correct installation method helps improve application stability, simplifies updates, and ensures long-term compatibility.
Why Install Java in Ubuntu?
Many enterprise applications require Java to function correctly. Ubuntu provides official repositories that make Java installation simple, secure, and easy to maintain.
Reasons to install Java in Ubuntu include:
- Run Java applications
- Deploy Spring Boot projects
- Host Minecraft servers
- Build Android applications
- Run Jenkins automation
- Execute Apache Tomcat
- Use Elasticsearch
- Develop enterprise software
Because Ubuntu includes trusted package repositories, installing Java is safer than downloading software from unknown sources.
Install Java in Ubuntu Using OpenJDK
The easiest way to install Java in Ubuntu is by using OpenJDK, the official open-source implementation of the Java Platform.
Step 1: Update Ubuntu
First, update your package list.
sudo apt update
Updating packages ensures Ubuntu downloads the latest Java version available from official repositories.
Step 2: Install OpenJDK
Install the default Java package.
sudo apt install default-jdk -y
Alternatively, install a specific version such as OpenJDK 17.
sudo apt install openjdk-17-jdk -y
OpenJDK 17 is currently one of the most widely recommended Long-Term Support (LTS) releases for production environments.
Step 3: Verify Installation
After installation completes, verify Java.
java -version
Example output:
openjdk version "17.0.x"
If the version appears successfully, you have completed the install Java in Ubuntu process.
How to Check Installed Java Version
Sometimes multiple Java versions are installed on the same server.
To verify the active version:
java -version
To locate Java:
which java
To display compiler version:
javac -version
These commands help administrators verify that Java has been installed correctly.
Install Multiple Java Versions
Developers often need different Java versions for different applications.
Ubuntu supports multiple Java installations simultaneously.
For example:
sudo apt install openjdk-11-jdk
sudo apt install openjdk-17-jdk
sudo apt install openjdk-21-jdk
This flexibility allows developers to test applications across different Java releases without reinstalling the operating system.
Switch Between Java Versions
If multiple Java versions exist, Ubuntu allows administrators to select the default version.
Run:
sudo update-alternatives --config java
Ubuntu displays all installed Java versions.
Example:
Selection Path
1 Java 11
2 Java 17
3 Java 21
Enter the preferred number to switch the active Java installation.
Choosing the Right VPS for Java Applications
Running Java applications requires sufficient CPU, RAM, and storage to maintain smooth performance. Small projects may run on entry-level VPS plans, while enterprise applications often require additional resources for databases, APIs, and background services.
If you’re planning to install Java in Ubuntu for production workloads, choosing a reliable VPS platform is just as important as selecting the correct Java version. You can explore Linux VPS Hosting for scalable virtual servers with dedicated resources, root access, and reliable infrastructure.
