What is a Java IDE?
An IDE, or integrated development environment, streamlines a developer’s individual environment and enables a developer to write, edit, and test code in a single application. This is more efficient than switching between applications for each of these functions.
Can I Write Java Code Without an IDE?
The short answer is yes: You can write Java code without using an IDE.
The long answer is: Why would you want to? Most Java IDEs are free for personal use (including Microsoft VSCode and Eclipse). Using an IDE to write to write Java code can make the process more efficient and offer tools for debugging.
What is a Lightweight Java IDE?
Back to topA lightweight Java IDE is an IDE that is fast, simple, elegant, and most importantly, more beginner friendly than more complex Java IDEs.
What’s the Most Popular Java IDE?
According to the 2025 Java Developer Productivity Report, the most popular Java IDE is IntelliJ IDEA at 84%. Behind, Microsoft VS Code, or Visual Studio Code, is second at 31% and Eclipse is close third at 28%.
Digging into the numbers deeper, and you'll find some interesting trends in the most popular Java IDEs over the past five years. IntelliJ IDEA has firmly held the top spot over that timespan, with the Java IDE's popularity only increasing.

Back to topOther Java IDEs
While the so-called “Big Three” of IntelliJ IDEA, Eclipse, and VSCode comprise the vast majority of IDE usage, those are not the only IDEs available. Read on to learn more about secondary IDEs including NetBeans, Rational Application Developer, Oracle JDeveloper, MyEclipse, and web-based IDE options.
NetBeans
NetBeans is a good choice for developers on a budget, or those who need a lightweight IDE. Because it's a free and open-source Java IDE, it can be a viable alternative to a paid IDE like IntelliJ IDEA Ultimate.
MyEclipse
MyEclipse is a commercially available Java IDE that’s built upon the Eclipse platform. MyEclipse integrates both proprietary and open-source code into the development environment.
Back to topAI Integration in Java IDEs
Generative AI writes Java code based on user input and Natural Language Learning models. The user completes a prompt about what they want the code to do in plain language, and the generative AI tool will return Java code that addresses the requirements set forth in the prompt.
Many IDEs are now adding AI extensions or plugins. Instead of copy/pasting AI-generated code from GitHub Copilot or ChatGPT, AI code generators integrated with IDEs, including VSCode and IntelliJ IDEA, are directly integrated and offer a seamless user experience.

Back to topCan You Use More Than One Java IDE?
Many Java developers have strongly-held IDE preferences, but that doesn’t mean that one is better than another. And it’s not a one-size-fits-all approach, either. Increasingly, Java developers are using more than one Java IDE.
According to the 2025 Java Developer Productivity Report, 42% of respondents are using more than one IDE in their Java development practice, with IntelliJ IDEA and VS Code being the most popular IDE combination.
Why Use More Than One Java IDE?
While fully-featured IDEs like IntelliJ IDEA or Eclipse attempt to offer all of the tools a Java developer may need in one comprehensive package, the reality is that no single IDE excels in all facets of code development. And as shops move to more than one development language, IDEs that support a polyglot environment become crucial.
