BlueJ vs Inteljava IQ

BlueJ is a free development environment for building Java programs, designed for beginners and teaching. It runs on Windows, macOS and Linux, with current downloads requiring a 64-bit operating system. Its interactive tools let users create and inspect objects, call methods, and evaluate Java expressions without compiling. In the editor, scope highlighting distinguishes code blocks and can help reveal misplaced curly brackets. BlueJ 6.0.0 added Kotlin editing and execution, though some Kotlin features, including code completion, are not supported. Documentation includes a Git teamwork tutorial for BlueJ 4 and later. Third parties can add functionality through an extensions API; the listed extensions page covers BlueJ 4 and older, while BlueJ 5.0.0 rewrote the API. The free Blueroom site offers teaching resources for educators. BlueJ directs software questions to its FAQ, technical support contact and bug database, and says it aims to respond to technical support requests within one working day.

Inteljava IQ is a Windows IDE for Java and other JVM development, with additional tools for web and enterprise work. After it indexes source code, it provides code completion, analysis during coding, and refactoring. Smart completion proposes types suited to the current context, while language assistance covers SQL, JPQL, HTML, and JavaScript, including expressions within Java string literals. Built-in tools include build and version-control tools, a decompiler, coverage, and database tools with SQL. Listed JVM languages include Java, Scala, Groovy, and Kotlin; named frameworks include Spring, Java EE, GWT/Vaadin, JBoss, Play, and Grails. The Community edition is for JVM and Android development and is open-source under Apache 2.0. Ultimate is for web and enterprise development under a commercial license. A free trial is available.
