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.

[michaeledie]

you are more useful than any of my university professors

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!

Muito bom que conteúdo Exemplar, que bacana e leve o jeito de fazer e explicar embora não entenda nada do que diz . Tá de parabéns Obrigado por compartilhar o seu conhecimento 👏

[angelcastineira]

your videos are getting better and better, this one helped me understand a lot better some previous concepts. thanks!

[amandatimmons]

I watched this video a thousand times this weekend and it helped me do and understand my homework assignment. thank you so much for such a good step by step video with explanations that are clear and easier to understand.

[primeoptumas]

Thanks for such a wonderful video lecture😍.

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.

very clear and helpful.
Thank you for that video

[elsaeelias]

It is very interesting to learn to catch concept of develop design; I expect another better video from you, thank you so much.

[hariom]

Please do as many projects as possible sir..Loved Your Concept..❤️ from india

[Bianchi]

Nice video, well done, thank you for sharing it :)

[mrCetus]

Hey Bro Code, thank You so much for dedicating the time to put this video together. It truly helped me to understand this new concept of Java for me.

[amedeekreuzer]

Thank you Bro Code, it all went very well and I could understand most of the code lines that you ecplained logically. Thank you very much!

[radosmirkovic]

Great tutorial. Keep on with the good work.

[azro]

As Java beginner, I've finished this after days of trying to understand 😁

[y.bgamesplayer]

Wow I got some idea from your work Thank you
