This is the codebase of the Learn Java Profiling course.
If you're already a student of the course, you can start exploring this through the lesson notes in the course.
Note that the code for each module is hosted on its own branch; you'll have to switch to the branch corresponding to the module you're on, for example: git checkout module1
