IDE stands for Integrated Development Environment which is a software that combines developer tools required to write and test applications. These tools include text editors, compiler libraries, and debuggers. In this article, we shall cover the installation and usage of IntelliJ IDEA on KDE Neon|Kubuntu.

IntelliJ IDEA is an IDE that is used by software developers due to its efficiency and built-in design to maximize productivity and minimize destructing developer flow. It has built-in tools that assist in detecting errors and bugs on the fly before you compile and run it. IntelliJ IDEA is written in Java Programming Language and also works with other JVM languages like Kotlin and Scala.

Its features include:

  • Has keyboard shortcuts for pretty much everything.
  • Has standard and custom themes which can be used to change the UI.
  • Accessibility features like using a Screen Reader.
  • Smart coding assistance like Intelligent code completion.
  • Has diagrams that help visualize and analyze your code.
  • Search Everywhere Dialog that helps in finding anything stored in the code base.
  • Has a powerful toolset that is used to run, build, debug and test code.
  • Built-in tools integration like terminal, database and profiler.
  • Supports version control systems like Git.
  • Offers support for leading frameworks and technologies used to develop modern applications and microservices.
  • Offers integration with popular container systems like kubernetes and Docker.
  • Bundled with JRE to run Java applications.

IntelliJ IDEA has two editions

  • IntelliJ IDEA Ultimate which has all the features mentioned, but not for free. Though, it has a free 30-Day Trial period.
  • IntelliJ IDEA Community Edition which has basic features but not all features like version control support and debugger.

System requirements

  • Atleast 2GB of RAM.
  • Atleast 5GB free.
  • Monitor Resolution of 1024×768.
  • 64bit Operating system.

In this guide, I will show you how to;

  • Install IntelliJ IDEA on Kubuntu|KDE Neon.
  • Customize themes.
  • Install Plugins.
  • Create a Java Project on intelliJ IDEA.

Install IntelliJ IDEA on Kubuntu / KDE Neon Linux

Download the Tarball file from the downloads page of the official website.

Save the file and click OK

You will find the file in the Downloads folder as shown below. You can rename the file or use it as it is.

Open your Konsole and navigate to the Downloads folder or the folder you file downloaded to. Then extract the file to the /opt/ directory.

cd Downloads
tar -xzf ideaIC-*.tar.gz
sudo mv idea-IC-*/ /opt/ideaIC

The extract command contains the name of the file downloaded. If yours is different, edit the command to fit the name. To check if the item was extracted, navigate to the opt directory and ls the items.

cd /opt/ideaIC

Then navigate to the bin folder and run the launching script. Again the command is with respect to the anem of the file extracted, Countercheck that.

cd bin

This launches the IntelliJ IDEA from the CLI and opens as follows. Accept the terms and conditions and click continue.

Next is to choose if you want to share data. Choose the option you want and continue.

Then it launches as below.

Then it opens as below.

You can customize the theme to your liking. I chose High Contrast.

You can install plugins that are required in your project.

You can learn IntelliJ IDEA like how to get started and use keyboard shortcuts.

Create a Project in IntelliJ IDEA

Click on the ‘+’ to create a new project. It opens the wizard to select the project framework. I will use Java.

If you do not have the necessary JDK to develop an app in Java, You can download it by selecting the ‘Download JDK’

It will open with the lastest version selected and you can just click Download.

Once downloaded, it will list on the SDK label as shown below. For this project, We do not require additional libraries so click on Next

After that click next to continue and name the project

Then the project opens. In the ‘src’ right-click and select ‘New’ then select ‘Java Class’.

Name the class as ‘com.example.helloworld.HelloWorld’. Then double click on Class.

It will create a class named ‘HelloWorld‘ and a package name ‘com.example.helloworld‘. It will open a project where you will put a simple ‘Hello World‘ script. You can append the following script.

public static void main(String[] args){
    System.out.printIn("<Your text here>");

The output is as follows

Then on the class line with the green play button, right-click and select Run ‘HelloWorld.main()’.

The project builds successfully and run as shown below.


In this guide, we have learned how to install IntelliJ IDEA on Kubuntu|KDE Neon systems. We have also learned how to customize themes and also seen that we can install different plugins that might be required for the project’s development process. We have also created a sample java project that also ran on the IDE.
