It's a great video well and clearly explained. As a Java beginner, it has saved me time and the headache I could have gone through in class. Thank a lot. I wish if you could do a video of the same but with a connection to MySQL database where the IDs and passwords would be store in the database.

[@Re9sTwitch]

Another great vid, very clear, well explained. Would be great to learn how you develop this code from scratch. Thanks again, keep up the great work!

First, I'm so glad that I found your channel. I started messing with Java because I understand it better than my wife and she's leaning on me to help her with her college class. She's sitting at a B, because she suffers test anxiety and doesn't really put in the work. Her final project is using 2D arrays and it bugs me because her class is so slow. I learned so much more by watching your videos and I've only been learning for less than a month. Second, I created a rudimentary RPG text based console game (complete with main menu, shop menu, inventory for shop and player, player classes, enemies, and enemy classes, combat engine, and combat menu). What I learned from you helped tremendously. I mostly did it on my own, but there were a few times that I had to google something. While googling, I ran into 2 scenarios that irked me. Which leads me to number 3 (last one). Third, I ran into lazy people basically expecting others to do their work for them (almost like my wife) and elitist MF's. The lazy people only bothered me a little. In the end, they're only hurting themselves. Elitists, though. Those people piss me off. Nobody is born with all the knowledge and all the skills. No one is born at the top of their field. Everyone starts at the bottom/beginning at some point. Elitist either forget that, or they like to pretend that they skipped that part and became a god at whatever it is that they're doing. This mentality hurts other people and can even turn them away. Plus they seem that everyone can read the docs (or man pages) and automatically understand it. However, everybody learns differently. Me, I learn by doing. I can read stuff all day long, or listen to someone all day long, and I'll never understand it. I have to do it for it to stick in my mind. Sorry for being long winded. Thanks, again, for doing these awesome videos.

[@makramziani2507]

bro i would hate to be your wife u bad mouth her way too much if it bothers u that she is lazy why did u marry her love her for who she is or dont waste her time

[@andromydous]

@@makramziani2507 Where did you learn to read? The only "negative" thing I said is that instead of her practicing, she looks to me to do it for her. If you're in school to learn something, especially if it relates to your chosen field, you should put the work in. That's not being negative. That's just facts. Besides, I could care less what you think.

[@makramziani2507]

@@andromydous ok habibi it might be facts that should be kept between you and her you can’t just go running around telling ppl how lazy your wife you might actually be one of the reasons she is lazy because you keep criticizing her you gotta be more supportive I am not tryna judge you or bad mouth you just an advice if you hate hearing this imagine her hating you hear she is lazy from you 🙄

I have to know, when you make these videos for practical applications, do you just do them on the fly, or do you make them ahead of time, then troubleshoot them and get them perfected before making the tutorials?

How can we create a sign up system and connect it with the log in system?
