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.
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 👏
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.
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.
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
@@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.
@@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 🙄
@@makramziani2507 Whatever, dude. Her and I have been married 22 years. I don't have to explain myself to you. If you can't read, then go get some help.
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?
hi, is there a video that covers registering users via admin menu? something like that? i'm having trouble creating multiple users. you might know what's wrong based on what I will say: when I register a member, it goes into the .txt file. but as soon as I create another one, the last one is removed. I know where my mistake is, but I don't know how to go around it! any tips?
thanks so much! although i hv a little problem, wherein my welcome page tab isn't displaying, overall, this tutorial is exceptional and helpful for me who's a beginner in java (GUI) .
If you can put source code on Github or somewhere it will be great... It look so messy on TH-cam comment. 😆 Thanks you for tutorial it really help me a lot.
It would be very kind, if you could tell me how to add an image to JLabel, so that I can have an image on the welcome page. Thanks a lot for the professional explanation in this video!
This is very new to me since my teacher on senior highschool only taught me basics about this and then focused on teaching me how to use JFrame Form GUI... btw, does bro have a tutorial about JFrame Form GUI with those palettes that you can drag and edit? I searched around and only found those that I can hhardly understand...
Can you make a second video on this for multiple details? Luke for a product were each cystomer got there own login info. Or can you do that with this obe aswell?
Hi, great video, very well explained, could you pls help me out a little, In this video you are doing many imports ,but in my eclipse the import option is not coming for listener method

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

yall doing this for assignments lol tuff imagine doing it in class and mispellng HashMap by mistake.
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.

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!
Thanks bud, it brings me back to my CSc labs in college!
My recent favorite TH-camr... Love from🇧🇩
Please do as many projects as possible sir..Loved Your Concept..❤️ from india
Thanks for such a wonderful video lecture😍.
Thank you so much for this man, easy to follow and undestand
As Java beginner, I've finished this after days of trying to understand 😁
Thank you very much ! Simple & easy and solved my pin point problems.
Amazing explain and session of coding
Very helpful for Revature's Java course week 3 project 1 work.
It is very interesting to learn to catch concept of develop design; I expect another better video from you,thank you so much.
Please do one where you mentioned, grabbing user login info from a file that was stored on a db, that would be dope my bro.
this is so much helpful
very clear and helpful.
Thank you for that video
Awesome I like the explanation
thank you so much, after watching your videos I more interesting to practice Java .... Cheers
i added the back and exit buttons to welcome page easily, thx for video
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?
bro, thanks a lot, you showed an easier way to make the same thing comparing to the way that i was doing
I hope you will create a tutorial about JavaDesignPattern or Android in your next video. Than you! :)
Super,simple,interesting
Wow I got some idea from your work Thank you
Thank you for this amazin class
very helpful for a beginners.
İt is very helpful. Thank you so much!
This was most of my school assignment, thanks.
That's true.. I enjoyed so much while wathcing this video. You expalained so well that I got it all ... Thankssssssss 🙃
Thank you! Simply but awesome!
All time best coding video Ever 🌟
Awesome tutorial!
Thank you Bro!
Great tutorial. Keep on with the good work.
This video is so helpful. Thank you.
Thank You BroCode. Helped me alot!
awesome
Bro Code, you are such a genius!
Great Explanation BRo
just what I needed, and it worked. thanks bro!!
quick question, why not just make the IDandPasswords class static, that way you won't have to make an instance of it in the main method?
it's easy to understand. Thankyou Bro Code
Thank you so much, you saved my life, by the way I love that there is a D&D file just chilling there
Thanks for your awesome content ❤
Awesome
Do you also have idea in using oracle database? Please release a tutorial for that too. 😊
Thank you, this is helping me a lot
rly interesting thank you.
it would be nice to do it with a database (could you do it ?)
Yeah maybe for a future video. It gets complex
Hello Bro
I learned alot from your tutorials.
your videos are soo helpful love from pakistan
Broo, thank you very much, this is exactly what I needed.
Thanks bro, this is so informative
Just here to complete the 2nd step you mentioned at the end
great stuff!
Thank you so much, this video is great!
Nice video, well done, thank you for sharing it :)
I was typing along with you till I realized you had the code below! LOL Thank you so much!
so read the comment first LOL!
Actually, Elizabeth, you did the right thing. typing code sets it in your head, and that is the important thing
I want to make an inventory system from this. Does that mean I have to just create multiple constructors?
great tutorial, thank you
Thank you so much for making this Video!!!!
Amazing
Nicee
hi, is there a video that covers registering users via admin menu? something like that?
i'm having trouble creating multiple users. you might know what's wrong based on what I will say:
when I register a member, it goes into the .txt file. but as soon as I create another one, the last one is removed.
I know where my mistake is, but I don't know how to go around it!
any tips?
Your voice is gooood❤️
Very nice. Thank you
Make more tutorial bro thanks! :)
this is a real chad. I hope to meet you one day, mr. bro
Thanks really helped me out
could you make a continue. How to create a account in this system? thanks for the nice tutorial
thanks so much! although i hv a little problem, wherein my welcome page tab isn't displaying, overall, this tutorial is exceptional and helpful for me who's a beginner in java (GUI) .
update: fixed it within 30 mins. ty chatgpt!
i love your videos brooo
your videos are so clear and short, essential
If you can put source code on Github or somewhere it will be great... It look so messy on TH-cam comment. 😆 Thanks you for tutorial it really help me a lot.
Wouldve loved it if you included user creation instead of it being already stated inside the code. But still great vid!
Thankyou for the video!
It would be very kind, if you could tell me how to add an image to JLabel, so that I can have an image on the welcome page. Thanks a lot for the professional explanation in this video!
identifier.setIcon(new ImageIcon("path"));
I reccomand watching his GUI video and going to the Label section
@@jbones2513 Alright, thanks
Thank you dear sir

Thank you
This is very new to me since my teacher on senior highschool only taught me basics about this and then focused on teaching me how to use JFrame Form GUI...
btw, does bro have a tutorial about JFrame Form GUI with those palettes that you can drag and edit? I searched around and only found those that I can hhardly understand...
this channel provided a 4hours long video about JAVA GUI ,check it you may find it helpful
You are uploading videos are more useful for me 'Thanks Bro'
can you upload how to connect with server our application videos
Thank you, helped me a lot. You saved my grades. hahah
super
👏👏👏
Really really good job, thank you !
Can you make a second video on this for multiple details?
Luke for a product were each cystomer got there own login info. Or can you do that with this obe aswell?
You would probably want to connect to a database for functionality such as that. I would need to release a database playlist first tho
@BroCodez do you have a database playlist yet? It would be reallllly useful
I think instead of ambiguously circuitous welcomlabel with new comstructor
jOptionPane might be more effacacious to break down some some complexity
hi, great tutorial, but does this work also when you have multiple users loging in that code ? thx for the answer;
Excelent Bro
Good
