Installing and Using IntelliJ IDEA for Java Projects for 2025

Installing and Using IntelliJ IDEA for Java Projects: A Comprehensive Tutorial


Developing a Java project is always a challenging task. As we embark on 2025, it’s essential to have a reliable and efficient Integrated Development Environment (IDE) to handle complex programming tasks with ease, speed, and flexibility. Among the many IDEs available today, IntelliJ IDEA stands out for its extraordinary features and capabilities that enhance the overall development experience.

In this tutorial, we will focus on installing and using IntelliJ IDEA for java projects. Whether you're a seasoned developer looking to switch IDEs or a beginner starting your programming journey, this guide will walk you through the complete process.

Installing IntelliJ IDEA


The first step is to download the IDE. IntelliJ IDEA is available in two editions: Community Edition (free), perfect for JVM and Android development, and Ultimate Edition (paid), which provides additional support for web and enterprise development.

To download IntelliJ IDEA, follow the steps below:

  1. Visit the official IntelliJ IDEA download page.

  2. Select the edition that you want to download.

  3. Once the download is complete, run the installer.

  4. Follow the instructions provided by the setup wizard to install IntelliJ IDEA on your machine.

After a successful installation, IntelliJ IDEA is ready to kick-off your Java programming voyage.

Creating a New Java Project


Here’s how to create a new Java project in IntelliJ IDEA:

  1. Starting IntelliJ IDEA: Upon starting IntelliJ, a welcome screen will appear. Click on the "New Project" option that appears on this screen.

  2. Project SDK: In the 'New Project' window, you will need to set up the 'Project SDK'. If an SDK is already configured, it will be automatically populated. If not, click on 'Add SDK' at the top of the window and add your JDK.

  3. Project information: Set the project name and location, then click on the 'Finish' button to create the new project. The IDE will display the project in the left-most pane, known as the 'Project tool window'.

Writing Java Code in IntelliJ IDEA


After you’ve set up your project, it’s time to write some Java code. As soon as you create a new Java class, IntelliJ IDEA opens a corresponding file in the editor and allows you to start coding.

This IDE goes beyond just syntactic assistance, providing intelligent suggestions in various contexts. It also comes with helpful quick fixes and smart navigation, making it easier to read, write, and change your code.

Compiling and Running Java Programs


When it comes to compiling and running Java programs, IntelliJ IDEA provides a seamless experience. Simply use the 'Build Project' command (Ctrl + F9). This command compiles the project and builds an artifact. If your program contains errors, the IDE will highlight them and provide quick fixes.

To run a program, all you need to do is right-click anywhere in the code editor and then select 'Run'. The output of the program is displayed in the 'Run' tool window.

Debugging Java Code


IntelliJ IDEA provides a comprehensive set of debugging tools and features. It offers variable expression evaluation, detailed view of call stacks, and a visual debugger. This powerful debugging environment gives you complete control over the program's execution, allowing you to diagnose and fix issues effectively.

The main advantage of IntelliJ IDEA is its simplicity and user-friendly interface that helps developers significantly reduce coding time. From installation to executing codes, debugging, and finally running tests, this popular IDE renders Java project development simpler and more manageable.

In conclusion, IntelliJ IDEA has emerged as one of the most utilized IDEs for Java development. If you're not using it yet, now is a great time to explore it and enjoy a smoother and more productive coding experience.
