It has been developed since 2001, and its popularity owes its popularity to built-in refactoring tools, i.e. the process of modification of the existing software while maintaining the adopted patterns and the overall quality of the code. IntelliJ IDEA Community Edition offers the programmer all the necessary tools and functions for convenient code writing and its subsequent expansion.

These include an intelligent code editor with syntax highlighting and auto-complete options, refactorisation and code inspection tools, a built-in XML editor and version control mechanisms that support CVS, Subversion, Mercurial and Git systems, as well as visual wizards for graphical interfaces based on the Swing library. The environment supports such programming languages as Java and Groovy, and additional plugins introduce support for Scala and Clojure, among others. In addition, it has integrated JUnit and TestNG frameworks, allowing for comprehensive testing of manufactured software.

The latest version of IntelliJ IDEA Community Edition offers full support for Java 7 and SDK for Android. The Community Edition has some limitations compared to the commercial version marked by the manufacturer as Ultimate. In the free edition you will not find support for Java Enterprise Edition technologies (including JSP, EJB, JSF, JPA and many others) and additional programming languages (Ruby/JRuby, Python, JavaScript/ActionScript, PHP and others).

More on the differences between the two releases of IntelliJ IDEA can be found on the manufacturer's website.
