What is jGRASP?
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 1.5 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.
Microsoft OneDrive On-Demand Problems
If you are attempting to compile Java source files from a OneDrive folder on Windows 10, the compile may fail with a “not a file” message. You can correct this by turning off “Files on Demand” in the OneDrive settings, if you have sufficient disk space for all your OneDrive files. Otherwise, you will need to copy the source files to a normal folder to work on them, then back to the OneDrive folder when done.
How To Use It:
To run jGRASP and develop Java programs, you will need the JDK with Java version 1.6 (JDK 6) or higher. You can get this by installing a jGRASP distribution that is bundled with OpenJDK. Otherwise, you may use any Java distribution, but we currently recommend an OpenJDK distribution that has installer packages for Windows and MacOS, such as AdoptOpenJDK. On Linux and Unix systems, the JDK or JRE “bin” directory must be on your system path.
