I took this course in my mid-30s to change my career from mechanical engineering to software development. When I was in college, my teaching assistant would give me a rough explanation or I would study on my own with a book, but I would often get confused about capitalization and give up on methods. But thanks to the great teaching this time, I was able to easily understand the concept of object orientation, which sounded scary. I still don't know what field I will pursue as a developer, but I will study the Spring roadmap and other fields for now and wait for the intermediate level. Thank you for making such a great course.
