- The Intro to Java course was able to break down multiple concepts into easily digestible chunks. I actually felt like I was practicing the information the moment I was learning it, as opposed to just watching a video and trying to remember what was said afterwards.Mike M.Verified Learner
- Very organized course overall, well-structured sub-tasks and great quality tips and notes in every lesson. For someone with a Codecademy subscription, and no background in Java, this course does the job of setting up the foundations and developing a critical-thinking repertoire to tackle problems in Java.Elie C.Verified Learner
