What Java IDE is good for programming?What Java IDE is good for programming?

At IDR Solutions we spend a lot of our time working with Java as our JPedal Java PDF Library, BuildVu PDF to HTML5/SVG converter  and JDeli Java Image Library are written in Java.

Our developers spend a lot of time buried in Java code and we use a variety of different IDEs (Integrated Development Environments) to develop Java code, so I thought it would be good to compile a list of the best free IDEs out there for Java programmers, developers and coders.

In this article, I will be taking a look at 11 different IDEs. Everyone has different requirements and we feel one of the strengths of the Java world is the choice available.

These IDEs offer a variety of features: building Java applications, TestNG, debugging, code inspections, code assistance, JUNIT testing, multiple refactoring, visual GUI builder and code editor, Java, Maven build tools, ant, do data modelling and build queries, and more.


NetBeans is an open-source Integrated Development Environment written in Java. Development of NetBeans has really accelerated since it became part of the Apache project.

The NetBeans IDE supports the development of all Java application types (Java SE, JavaFX, web, EJB and mobile applications) out of the box. NetBeans is modular in design. This means it can be extended by third-party developers who can create plugins for NetBeans to enhance functionality (Our PDF Plugin for NetBeans is a good example).

NetBeans has now moved to Apache, making it easier for people to get involved and contribute. They have a new website explaining more about Apache NetBeans.

The NetBeans IDE can be used to develop in Java, but also supports other languages. These include PHP, C/C++, and HTML5.

NetBeans features include an Ant-based project system, support for Maven, refactoring and version control (supporting CVS, Subversion, Git, Mercurial and Clearcase). It is also released under a dual license. These consist of the Common Development and Distribution License (CDDL) v1.0 and the GNU General Public License (GPL) v2.

NetBeans is cross-platform and runs on Microsoft Windows, Mac OS X, Linux, Solaris and other platforms supporting a compatible JVM. It can also be used for working with Cloud applications. This useful guide covers how to use the NetBeans IDE with the Google App Engine.

If you would like to find out more about NetBeans we have a series of articles which includes lots of tips and tutorials.


Eclipse is another free Java IDE for developers and programmers. It is mostly written in Java. Eclipse lets you create various cross-platform Java applications for use on mobile, web, desktop and enterprise domains.

BlueJ is an integrated development environment (IDE) for the Java programming language. It has been mainly developed for educational purposes. However it is also suitable for those who wish to do small-scale software development. It runs with the help of a JDK (Java Development Kit).

BlueJ is mainly developed for the teaching of object-oriented programming. Its design differs from other development environments as a result.

The main screen graphically shows the class structure of an application under development. Objects can be interactively created and tested. This interaction facility, combined with a clean, simple user interface, allows easy experimentation with objects under development. This allows beginners to get started more quickly, and without being overwhelmed.

Newbie users can check values and call methods on objects. They can also pass them as parameters and Java expressions can be invoked without compiling. This means BlueJ is a powerful graphical shell/REPL for Java.

The BlueJ project is free and open source software. It is licensed under GNU GPL with the classpath exception. There are popular textbooks designed for teaching introductory university/college courses with BlueJ. There is also a site full of teaching resources. It can run on Windows, Mac OS X, Linux and other platforms which run Java. It can also run without installation from a USB stick.


jEdit is a text editor with hundreds (counting the time developing plugins) of person-years of development behind it. Most people argue that jEdit beats many expensive development tools for features and ease of use. In particular the jEdit core comes with a built-in macro language. This is an extensible plugin architecture. Hundreds of macros and plugins are available.

There is also an auto indent function, and syntax highlighting for more than 200 languages. It has support for a large number of character encodings including UTF8 and Unicode. Plus folding for selectively hiding regions of text, word wrap, and more.

It can also  be used for source code editing, search and replacing and file management. jEdit is written in Java, so it runs on Mac OS X, OS/2, Unix, VMS and Windows. It is released as free software with full source code, provided under the terms of the GPL 2.0.


jGRASP is a lightweight IDE, primarily created for automatic generation of software visualizations to improve the comprehensibility of software. It is capable of producing static visualizations of source code structure and visualizations of data structures at runtime. jGRASP produces Control Structure Diagrams (CSDs) for Java, C, C++, Objective-C, Python, Ada, and VHDL. Complexity Profile Graphs (CPGs) for Java and Ada are also supported. As are UML class diagrams for Java. It has dynamic object viewers and a viewer canvas. This works in conjunction with an integrated debugger and workbench for Java.

The viewers have a built in feature that allows them to identify data structures. This means they can recognize objects that represent traditional data structures. For example stacks, queues, linked lists, binary trees, and hash tables. These can then be displayed appropriately.

jGRASP is implemented in Java. It was developed by the Department of Computer Science and Software Engineering in the Samuel Ginn College of Engineering at Auburn University.

It can run on any platform that can run a Java Virtual Machine (Java version 1.5 or higher). At present the jGRASP web site offers downloads for Windows, Mac OS, and as a generic ZIP file suitable for Linux and other systems.
