Java exam cheatsheet
Was just allowed to take one full A4 (double sided) notes to the exam for reference purpose. So I decided to use InDesign to set the fonts at 6 pt which for me, is the smallest viewable size of font and put most of the contents that I learned into this cheatsheet. I think it helps very much, not only for the exam, but also for a general overview of Java (not very much advanced, though)
I'm pretty much sure you cannot really view it from the images uploaded cuz it's too small for some reason on here. Just download it and use it or whatever: https://9oelm.github.io/java-exam-cheatsheet-one-paper/
