I decided to take the Java class because it was an elective for my major, and I felt there were limitations to learning it on my own. Since I had encountered C language first, it was difficult to understand Java concepts, but the professor not only explained the differences between C and Java but also specifically pointed out and explained, "While it works this way in native code, Java processes it this way!", which was very helpful. Due to my shortcomings, I regret not getting the grades I wanted on the midterm and final exams, but I think it was helpful just to learn what the Java language is and how it works. If I were to give a tip to students, I recommend going to a library or bookstore, buying a basic Java concepts book that suits you, and studying along with it. Listening to lectures is good, but it might create a misunderstanding of what you've understood, so I recommend reading it in text, listening to lectures, and doing both simultaneously. Don't skip all the codes in the PPT; execute each one at least once and review them. If names overlap, it's good to just create another directory and repeat. Lastly, I recommend asking an AI to generate problems relevant to the topic and solving them yourself.
