# How To Install Java On Ubuntu 26.04 LTS (Linux)
In this complete step-by-step tutorial, you'll learn **how to install Java on Ubuntu 26.04 LTS** and configure your Linux system for Java development. Java is one of the most widely used programming languages and is essential for building desktop applications, backend services, enterprise software, Android applications, development tools, and many other types of software.
Whether you're a beginner learning Java, a software developer, Linux user, student, DevOps engineer, or preparing your Ubuntu machine for programming, this guide will show you how to install Java correctly and verify that everything is working.
In this video, we'll start by explaining **what Java is and why you may need it on Ubuntu Linux**. You'll learn about the Java Development Kit (JDK), Java Runtime Environment (JRE), and Java Virtual Machine (JVM), and understand the role each component plays when running or developing Java applications.
Next, we'll walk through the process of installing Java on **Ubuntu 26.04 LTS** using the Linux terminal and Ubuntu's package management system. You'll learn how to update your package lists, install the appropriate Java package, and verify the installation using standard Java commands.
Topics covered in this tutorial:
* What is Java?
* What is the JDK?
* What is the JRE?
* What is the JVM?
* Java installation on Ubuntu 26.04 LTS
* Updating Ubuntu packages
* Installing Java using APT
* Checking the installed Java version
* Checking the Java compiler
* Configuring Java environment variables
* Setting JAVA_HOME
* Managing multiple Java versions
* Switching between Java versions
* Troubleshooting Java installation problems
* Verifying your Java development environment
In the practical demonstration, we'll show you how to open the Ubuntu Terminal and install Java using simple commands. After installation, we'll verify that Java is available by checking the installed version and confirm that the Java compiler is working correctly.
We'll also explain how to determine which Java version your system is currently using and how to manage multiple Java installations if you need different versions for different development projects.
If you're planning to use Java for programming, we'll also cover the basics of setting up your environment so you can move on to writing and compiling your first Java application. You'll learn how Java source code is compiled and how the Java compiler and runtime work together on Ubuntu.
This tutorial is useful for anyone setting up Ubuntu as a **Java development environment**. It can also be a helpful first step before installing tools such as IntelliJ IDEA, Eclipse, Visual Studio Code, Maven, Gradle, Spring Boot, or other Java development frameworks and tools.
We'll also cover common issues beginners may encounter, such as Java not being found after installation, selecting the wrong Java version, configuring `JAVA_HOME`, and checking whether the Java compiler is correctly installed.
By the end of this tutorial, you'll know how to install Java on Ubuntu 26.04 LTS, verify your installation, understand the basic Java components, and prepare your Linux system for Java development.
