Introduction

There are multiple ways to install Java on Ubuntu but this is the simplest way to install Java. In this blog, we will guide you through the process of installing Java on Ubuntu.

Before we begin, let’s take a look at the different versions of Java available.

1. OpenJDK – This is an open-source implementation of the Java SE platform, and it is the default Java runtime environment on Ubuntu.
2. Oracle Java – This is a proprietary version of Java that is developed and distributed by Oracle Corporation.

There are other versions of Java available, but we’ll focus on installing OpenJDK on Ubuntu.

Step 1: Upgrade your system to latest version

Before you begin the installation process, it’s a good idea to update your system’s package list and upgrade any existing packages to their latest versions. Open a terminal and run the following commands :

sudo apt upgrade -y

Once the system upgrade process completed, We will check whether Java is already installed in the system.

java -version

If Java is already installed, You will get below like output with Java version details :

sudo apt install default-jdk

sudo apt install default-jre

In this case we are installing JDK – 17 but to install specific version of Java replace “17” with your version and run the following command :

sudo apt install openjdk-17-jre-headless

To check all the version of Java available to install visit official Java release page.

After successful installation we need to verify the Java installation and it’s version. To do that we can run Step-2 command or run below command :

java -version
