Best Java IDEs of 2025: Top 6 Picks by Our Developers

In order to take full advantage of the capabilities of Java, programmers can use special tools to facilitate writing code and creating applications.
This role is played by Java development environments (Java IDEs).

In this article, we will answer the following questions:

• What is an Integrated IDE Development Environment?
• What makes a good Java IDE in 2025?
• What are the most popular free JAVA IDEs in 2025, and what are their pros and cons?
• What functionalities should a good IDE platform contain?

Best Java IDE: What is an Integrated Development Environment?

The IDE is an integrated development environment that helps you build your application by combining various development tools into one universal system.

The average IDE usually consists of a java code editor, compilation automation tools and a debugger, but typically modern environments also include a number of additional, useful functionalities.

The most important advantages of using an integrated programming environment include:

• Integrated development environments reduce the configuration time required to link multiple development tools.
• The tools and systems contained in the IDE are packed into one consistent and transparent user interface.
  Thanks to this, a programmer who is not fully familiar with a given functionality will learn it much quicker.
• Most modern IDE development environments include tools that let the developer add comments to code in a faster and seamless manner.
  Thanks to this, project documentation can be created much swifter and more efficiently.

What makes a good Java IDE in 2025?

When deciding to use the Java IDE, it’s important to first determine what you need.

This way, you will make sure that the Java development environment contains the necessary tools for your needs.

Regardless of your level of experience, there is an ideal Java IDE for you.

Any good Java development environment should include at least these features:

Validation

Any good IDE should have a tool to highlight minor mistakes and bugs in the code so as not to cause additional problems and delays.

Automatic code compilation

The Java development environment should allow developers to write and run code in the same window. This increases the productivity and efficiency of the entire system.

Syntax highlighting

A robust IDE should include functionality to highlight important java code elements. This solution can help you find potential bugs in the code and make the code easier to understand.

Clean Graphical User Interface (GUI)

The powerful GUI of the development environments facilitates the work and enables programmers to learn more quickly the functionalities that they have not dealt with before.

Code Completion

Many modern IDEs have tools that automatically identify and fill in missing code components to save time and reduce the risk of minor bugs, typos, and errors.

It is worth noting, however, that the best Java IDE is one in which you will feel at ease. The choice of an Java IDE depends entirely on the specifics of the project, as well as the selected technologies and equipment.

Best 6 Java IDEs in 2025

1. IntelliJ

IntelliJ IDEA is a popular Java integrated development environment that is widely used by development companies around the world.

It is fully equipped with highly efficient tools and features that are helpful in the developer’s work.

The first version of IntelliJ IDEA was released in January 2001. It was one of the first Java IDEs with advanced code navigation and integrated refactoring functions.

In addition to supporting Java programming language and many Java frameworks, IntelliJ IDEA provides support for other JVM-based programming languages such as Kotlin.

IntelliJ is by far the favorite among developers in Stratoflow.

The major advantages of this environment are, among others, much better optimization and stability as compared to other solutions, as well as the availability of many additional plugins and synchronization of settings.

Selected functions:

• Advanced Debugger
• Decompiler
• Language injection
• Detecting duplicate
• Quick search
• Chain Completion
• Quick completion
• Refactoring (the process of automatic improvement of the internal code structure)

Advantages:

• Numerous additional functions and plugins
• Stability
• Very good technical support
• Automatic generation of basic code
• Simple and functional interface

Disadvantages:

• Relatively expensive subscription in the Ultimate version
• Uses a relatively large amount of computer resources

2. Eclipse

Eclipse is yet another popular Java integrated development environment in 2025. It’s one of the best best free java ides on the market.

It includes a basic workspace that can be expanded to meet the needs thanks to the entire plug-in system.

The VisualAge family of integrated development environment (IDE) products powered by Smalltalk inspired the creation of Eclipse.

According to Lee Nackman, then IBM’s chief technology officer, the name Eclipse was meant to refer to the company’s main competitor – Microsoft and their Visual Studio environment, which Eclipse was supposed to “eclipse”.

Subsequent versions of Eclipse also received names related to science and astronomy, such as the versions of Callisto, Europa, and Ganymede, which refer to the moons of Jupiter.

The Eclipse Development Kit (SDK) is intended primarily for Java programming.

However, users can extend its capabilities by installing plugins written for the Eclipse platform, such as development toolkits for other programming languages. You can also write and contribute your own plug-in modules.

The Eclipse IDE is available in both a desktop and a cloud-based version. The cloud version of Eclipse, named Eclipse Che, allows developers to build applications via a web browser.

Eclipse is often compared to IntelliJ and many Java developers point these two as the best Java IDE.

For one of our programmers, it was Eclipse that turned out to be a better choice.

According to him, Eclipse has better plugins for languages/toolsets/SDK, which cannot be found in competing solutions. Moreover, he noted that although IntelliJ has better stability, it uses much more computer resources, in particular the CPU and disk.

Selected functions:

• Runtime core
• PDE (Tool for creating custom plugins)
• Modeling and control language
• Automatic syntax checking
• Interfaces designed for custom solvers
• Custom Compiler
• Easy-to-use functionalities for editing, viewing and refactoring
