Your examples are amazing. I Really gotta give you props on how clear and complete you make your explanations. From defining the actual word and giving it some context, providing a simple example, and then showing a use case. It's just top notch work my guy. I wish you the best!
this is really high quality content!!, and your way in explaining the things make them so easy to understand; I was so scary from the inner class for months for now until this video.
In Chinese there is something calls 匿名内部类，匿名对象，means a inner class or object without a name,it is convenient to use it if you want to use it only once a time.which always used to implement interface and override method, and it is very basic knowledge for us to know because if we don’t familiar with it , it will be hard for us to understand lambda expression.
Chinese teachers teaches their students by using very boring examples and it’s make me very hard to remember. And I really don’t know why they don’t teach me anything about Java swing classes such as JFrame or event. Action listeners. Your example is really easy to remember and it’s more interesting. And by the way, button1.addActionListener can be replaced by lambda expression so that it makes code more beautiful and easy to read.
I remember that when I learned android studio , I have learnt something like this : Button btn = (Button) findViewById(R.id.button) ; btn.setOnClickListener(welcome) ;
// Once the onClick event is detected , run the code below . public View.OnClickListener welcome = new View.OnClickListener() { public void onClick(View v) { // code block } } ; I figure out that I can write it in a similar way in eclipse : button1.addActionListener(welcome) ;
public ActionListener welcome = new ActionListener() { @Override public void actionPerformed(ActionEvent e) { System.out.println("Hello") ; } } ; Android studio and the GUI functions similarly . I was confused of that strange structure . Now you let me know that it is anonymous class . Thank you bro . The funny fact is that my tutor teaches me to use the methods (more difficult) mentioned above before teaching us to use implements which is very efficient for handling many buttons .

Great content! Honestly one of the best coding channels out there. Keep up the great vids!
I love this guy's tutorials. I've learnt so much from him.

I literally love you for the stuff you've done for us struggling
Bro Code, you are very under-rated. Your tutorial videos are really helpful. Love from Myanmar.
Gracias hermano

didn't hear of that programming language

Excellent video. Thanks for the knowledge.
I am learning so much from you bro, thank you
thank you bro
I learned something new
Very nice BRO ;)
Keep up!!

That is true. I want to make a video on lambda soon, however it's taking a lot of time because it's difficult to explain
Bro Code thanks! On that course I must try my best to understand it. Because it is really hard to understand.
You're a lifesaver
Great Video, you have a new suscriber now. Thanks
81th. Thank you, ma Bro Sensei
I am really happy to see ur video as i expected and got what i need ..tqqq so much...
Thanks. Great explanation!
that´s neat bro, I had always done it by typing all that "crap" ( x'DDD) at the beggining, now you enlightened me haha, thanks sr !
hey Bro, superb lesson!
Hey thank you for the Java content Please make video about Arrays and maybe Array.list in while loops so I can print all after the loop its over
Don't know what Jframe is but thank you so much for explaining
And why method name Welcome capitalized? Just to confide beginners?
thank you ! your videos are great !
Commenting to help BRO
Something professional like "yo bro!"😂😂
thats some Good content Bro!
niceeeeeeeee and cleannn explanation Bro Code! Thanks a lot!!!!
thanks for watching Temur!
Your channel should have got more viewer bro
Very helpful bro..!
nice tutorial
Chefs kiss
thanks for making me pass my OOP exam lol
Hi!
Thank you so much Bro!!
Can anyone help I'm getting an error saying can't find symbol for class MyFrame? 😢
Thank you!
Thanks
Ly bro 9
thanks bro
thanks bro💛
🤩
THANK YOU
thank you
What is and is not in scope in the anonymous inner class?
i found it thx
thank you!
Aren't methods supposed to be lowercase?
:)
where is the code
I'm probably too late but it's in the description
Help me, help you
