Asking help to find tips on JShell source code parsing

[Nazzareno Sileno]

Hi all,
I'm trying to develop an educational tool that uses Jshell as a programming
language. The tool must track the source code execution and it must produce
commands. Commands are the inputs of the JavaFX 3D engine, they are used to
transfer the minimal set of informations needed to reproduce the animations
about the running source code. I want to use a consistent metaphor to teach
the fundamental concepts about the procedural programming and the object
oriented programming.
I'm looking for something like a source code parser that I can use to
extract informations about the execution flow to fill the commands. In
particular I am interested in reproduce every single: declaration of
variable, expression evaluation, passing parameters operation, method
execution and termination, object creation, control flow statement, input
and output stream.
Could you suggest a solution to address these issues?

The SnippetEvents are not enought to achieve the goal. They do not track
every single line of code execution. I need to symulate the source code
execution step-by-step.
