DrJava vs JuiceMind Java IDE

DrJava is a free, open-source development environment for writing Java programs, designed primarily for students. Its intelligent editor supports coding, while the Interactions pane lets users evaluate Java code interactively. The environment includes JUnit testing, a source-level debugger and Javadoc generation for source files. It runs on Windows, macOS and Linux under a standard BSD open-source license. The current beta is compatible with Java 8, identified by the project page as the only supported version of traditional Java. That beta is distributed only as a JAR, which the page says is intended to reduce cross-platform compatibility issues. The Eclipse plugin is described as very old and compatible only with Eclipse versions from the same era. The Linux FAQ reports an incompatibility with the Compiz window manager and recommends disabling Compiz if it occurs. Bug reports and feature requests require a SourceForge account login. The Free plan costs nothing, with no free trial listed.

JuiceMind Java IDE is a browser-based Java environment for AP Computer Science A and K-12 classrooms. It compiles and runs Java in the cloud, so devices need no local JDK or installation. The IDE works on Chromebooks, tablets, and other web-browser devices. Teachers can configure unit tests that run against student code and return automatic feedback. Compiler messages and stack traces identify error lines, and a line-by-line debugger is described. Supported AP topics include classes, arrays, ArrayList, and recursion. Student work saves automatically, can be shared by link, or submitted for grading. LTI integration works with Canvas, Google Classroom, and Schoology. The product also describes real-time group projects and 24-hour customer support. The free Starter plan is free, with limited introductory Java and curriculum-aligned exercises and three AI-graded submissions. Teacher Pro and School & District use custom pricing. JuiceMind was founded in 2021.
