Greenfoot vs Jvdroid

Greenfoot is educational software for learning object-oriented programming with standard Java code. Learners build games, simulations, and other graphical programs by placing actors in worlds. The programming environment combines visualization and interaction tools with an IDE that includes project management, auto-completion, and syntax highlighting. Projects can be published online for others to play and comment on, and sharing is built into the environment. Greenfoot runs on Windows, macOS, and Linux; downloads cover Windows 10 and 11, macOS 11 and later, Ubuntu with Debian support, and a generic option for systems with JDK and JavaFX. From version 3.6.0, Intel/AMD systems need a 64-bit CPU and operating system; version 3.5.4 is the listed option for 32-bit support. The software is free, and its IDE source code is available under the GNU General Public Licence version 2 with classpath exception. Learning resources include written and video tutorials for beginners and advanced users, along with the Greenroom instructor community.

Jvdroid is an educational Java IDE for Android with an offline compiler, so Java programs can run without an internet connection. It includes standalone OpenJDK 11 and supports Maven projects and libraries. Maven can build Kotlin, Scala, and Clojure programs, although Jvdroid does not provide code prediction or analysis for those languages. The editor offers a Javadoc viewer, code formatting, syntax highlighting, themes, tabs, and one-click sharing to Pastebin. Code prediction, automatic indentation, and real-time code analysis are marked as Premium features. The Free plan costs nothing and contains ads and in-app purchases; a Premium plan is listed without a price. At least 250 MB of free internal memory is required, with 300 MB or more recommended. Jvdroid does not build native Android applications. Google Play says the app may collect location and personal information, share location and financial information with third parties, encrypt data in transit, and not allow data deletion. BusyBox and OpenJDK in the APK are GPL-licensed.
