That’s why we have designed this guide to assist you with the top 11 free Java IDE 2021. Before we get into the list, we need you to know the essential features a good Java IDE should have.

What are the Ideal Features of Java IDE?

The IDE is a short-term Integrated Development Environment that comprises all the necessary Java tools that you require to build powerful Java applications. The IDE helps you write, debug, and test your Java code for creating applications. Developers are able to work in a single environment and improve their workload using IDE tools. Each IDE comes with different resources and each of them includes text editors, build tools, debuggers, etc. To identify which IDE is best for your needs, you need to be sure of what you expect out of it. So, here are the essential features of the IDE that you might need, no matter how experienced or beginner developer you are.


The type of debugging an IDE provides varies from one IDE to another. But it is important for all IDEs to have a debugging tool that will identify the potential errors of codes and help you improve them quickly.

Highlighting errors

An IDE comes with a built-in highlighting tool that will help you highlight the errors of the code. In this way, you can resolve the errors to make your codes more efficient and readable.


The IDE helps you write and run your Java code at the same time you are working on your program to make it more efficient.

Code completion

Code completion allows you to identify and insert components of codes into the application so that you can save time and also reduce the risk of typos and glitches.

Graphical User Interface (GUI)

An IDE should provide you with an attractive Graphical User Interface (GUI) so that your web applications also come with a modern user interface.
