Java anonymous inner class 🎭

Java anonymous inner class tutorial

#java #anonymous #class

public class Main {

public static void main(String[] args) {

/*anonymous class = an inner class without a name
only a single object is created from one
The object may have “extras” or "changes"
and no need to create a separate innerclass
when it only need it once.
Helps us to avoid cluttering code with a class name

Syntax is similar to a constructor,
except that there is also a class definition
within a block of code.
GREAT FOR LISTENERS

Great content! Honestly one of the best coding channels out there. Keep up the great vids!

[ryan_millard]

I love this guy's tutorials. I've learnt so much from him.

[frilledshrimpo]

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!

[ramien]

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.

Great content! Honestly, one of the best coding channels out there. Keep up the good work.

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.

Gracias hermano <3
Something I really love of your videos is how you pronounce so clearly that even a non English speaker can understand

[eugenezuev]

I literally love you for the stuff you've done for us struggling

[lynnmyat]

Bro Code, you are very under-rated. Your tutorial videos are really helpful. Love from Myanmar.

[expansivegymnast]

Excellent video. Thanks for the knowledge.

[bentameurmohammedayoub]

thank you bro <3 your way of explaining is very interesting and beautiful, love from algeria <3 .

[hyperkarlotheweeb]

I am learning so much from you bro, thank you

[cheke]

Great Video, you have a new suscriber now. Thanks

[ShiroVK]

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

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.

Something professional like "yo bro!"😂😂

[rafaarteaga]

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 !

[kiruthikas]

I am really happy to see ur video as i expected and got what i need ..tqqq so much...

[Dankake]

Don't know what Jframe is but thank you so much for explaining<3
