  IntelliJ IDEA for Beginners: How to Set Up Your First Java Project the Right Way

  Posted by Carl on December 12, 2025 at 2:36 am

  Getting started with Java development can feel a little overwhelming, especially when you’re new to both the language and the tools. Fortunately, IntelliJ IDEA—often simply called intelli by many developers—makes the process much more approachable. If you’re just stepping into Java development, here’s a simple and human-friendly walkthrough to help you set up your first project the right way. First, when you open IntelliJ IDEA, you’ll be greeted with a clean welcome screen that lets you create a new project. Choose “New Project,” select Java, and make sure you have the correct JDK installed. IntelliJ is pretty smart—it will detect available JDKs automatically or let you download one right from the interface.

  For beginners, the default settings are usually perfect, so there’s no need to tweak anything advanced just yet. After creating your project, IntelliJ generates the basic structure for you. Inside the src folder, you can create your first Java file—typically a simple Main class. IntelliJ helps by offering templates, auto-suggestions, and error checks as you type. These small touches really help beginners avoid common mistakes early on.

  One of the best habits you can build from the start is organizing your code properly and running it often. IntelliJ provides a super convenient green “Run” button that executes your program instantly. As your projects grow, tools like Keploy can even help you generate tests automatically based on your application’s behavior, making early testing easier than ever. Finally, spend a bit of time exploring the environment. Intelli’s sidebar, code completion, and built-in terminal make it a complete development space without needing extra setup. Setting up your first Java project the right way in IntelliJ IDEA isn’t just about getting it to run—it’s about establishing a smooth workflow that will help you grow confidently as a developer.
