Dialogs Freezing on MacOS Big Sur
If you are experiencing dialogs freezing on Big Sur, here is a temporary work-around:
Java Compiler
- Shut down jGRASP if it is running.
- From the Apple Menu go to 'System Preferences' > 'General'.
- For 'Prefer tabs when opening documents', select 'never'.
This will of course affect other applications that use that setting. We are working on a permanent fix for the next jGRASP release.
New Features
jGRASP version 2.0.6_09 Beta adds CSD and run support for new Java 17 language features (sealed classes).
jGRASP version 2.0.6_08 Beta 2 adds CSD and run support for new Java 16 language features (records and pattern-matching instanceof).
jGRASP version 2.0.6_08 Beta supports system UI scaling on Windows and Linux (automatically integer-rounded). Previously only fonts and custom icons were scaled. Now scaling will also apply to system icons on file choosers, border thicknesses, spacing and margins, etc.
jGRASP version 2.0.6_05 Beta adds CSD, interactions, and run support for Java 15 features (text blocks).
jGRASP version 2.0.6 includes dark themes.
The jGRASP Plugin for Eclipse version 1.0.0 Beta 6 adds support for the Eclipse dark theme.
About jGRASP and jGRASP Plugins
jGRASP is a lightweight development environment, created specifically to provide automatic generation of software visualizations to improve the comprehensibility of software. jGRASP is implemented in Java, and runs on all platforms with a Java Virtual Machine (Java version 1.8 or higher). jGRASP produces Control Structure Diagrams (CSDs) for Java, C, C++, Objective-C, Python, Ada, and VHDL; Complexity Profile Graphs (CPGs) for Java and Ada; UML class diagrams for Java; and has dynamic object viewers and a viewer canvas that work in conjunction with an integrated debugger and workbench for Java. The viewers include a data structure identifier mechanism which recognizes objects that represent traditional data structures such as stacks, queues, linked lists, binary trees, and hash tables, and then displays them in an intuitive textbook-like presentation view.
jGRASP plugins for IntelliJ (IDEA and Android Studio) and Eclipse add the viewer and canvas features to those IDEs. For IntelliJ, the viewers and canvas will also work with Kotlin (JVM) code.
jGRASP is developed by the Department of Computer Science and Software Engineering in the Samuel Ginn College of Engineering at Auburn University.
Current Development
We are currently building a gdb/lldb interface for the debugger and visualizations in jGRASP, with support initially for C and C++ and the potential for other languages in the future. In parallel with this, we are developing a viewer/canvas plugin for CLion.
Acknowledgments
The development of jGRASP plugins for Eclipse, IntelliJ, and CLion and future jGRASP C/C++ visualizations is supported by the Auburn Cyber Research Center.
Prior development of jGRASP was supported by a research grant from the National Science Foundation.
The development of GRASP, the predecessor of jGRASP, was supported by research grants from NASA Marshall Space Flight Center, the Department of Defense Advanced Research Projects Agency (ARPA), and the Defense Information Systems Agency (DISA).
Looking for a free Java Compiler? You've come to the right place.
Here are some of the compilers that I have personally used throughout my Java programming career. As I find others, I will of course try them out and then if I like it enough I'll put it up here as well. If you have a compiler you'd like to recommend, feel free to contact me in the Contact Us section of the site.
Free Java Compiler For Mac Computers
Note: No matter what compiler you get, you'll need the JRE (Java Runtime Environment). If you don't have the JRE, you may download it at Java.com. Once at the downloads page, it automatically selects what it thinks is the correct version for your system. That is probably the version you should go ahead and download.
Compilers
Eclipse - This is my favorite IDE. The tutorials on this site all use Eclipse as it is extremely user friendly and the best professional tool for beginners. When at the downloads page select Eclipse Classic if you want just the basic features that will run Java.
Netbeans - Another great IDE, and the one I used before I discovered Eclipse. I still have Netbeans and find it easy to work with, although it's not AS friendly as Eclipse. Still, it is a great tool for development. When you're at the download page, if you only want Java and none of the other features, make sure to download the Java SE bundle, the one that is 31 MB.
JGrasp - JGrasp is a basic Wordpad-like program that also can compile and run Java programs. This is a standard beginners compiler and used by many schools that teach Java. I'm not the biggest fan of this program although I used to use it before I discovered the power of true IDE's. I don't like JGrasp much because it isn't a professional tool used in the real-world, and is more for hobbyists and those learning. It also does not come with the JDK (Java Development Kit), so you'd have to download that separately if you don't already have it.
