I still remember how Intellij taught me about this feature of Java ! It was the first time i learnt something from an IDE. Great experience 😅

Hi Dan, can you please make a video about heap and thread dumps. How can we investigate them, which valuable data can we retrieve, and how to operate efficiently with it

[mrMarseleene]

I already knew that, but it was nice to make sure that i still had that knowlage!
always glad to watch your videos

[swipped]

More quality java content is always nice, ty Dan

[MohamedDernoun]

The way you are explaining is fascinating ❤

If you're planning on doing more of these Java ones, could you consider a Beginner, Intermediate and Advanced tutorial on Optional. Particularly focusing on refactoring a method that checks for null the old way.

Hey Dan nice vidoes, please show more content about stream processing with spliterator and how to work efficiently in parallel

Hi Dan, could you look into reactive Java? Ive seen it used alot with Spring.

Another great video. Thanks Dan! One thing I'm still puzzling over: Why the :: syntax? If I want to use a method I use the dot operator, like: object.method() and in some other languages, if I want a reference to the method I can just use the dot without calling the method to get a reference to the method, see: object.method. Is there a reason why there's a specific syntax that seems to me to be dedicated to getting a reference to a method, as opposed to using a syntax that is consistent with accessing other properties on an object (the dot operator)? Maybe there is something fundamentally different about accessing method references vs other object properties that I am missing because Java is not my first programming language?

Good idea Dan, I would like to learn Java from you.

5:35 but println is not a static method. Isn't that what you call a bound receiver?

[Reclusive_shayar]

How does using unnamed classes gonna change the current spring boot development ?

[kacpergrabiec]

Can you make a video about spring websocket (and security)?

[haroldpepete]

if you're using java 21, why not use a unnamed class, new { ... } and you avoid to write all that bolierplate code

[SandipChitale]

Without IDEs to help it make it harder to read the code as the signature of the method is hidden by this syntax. To be fair almost very one uses IDE. Conciseness is not always good. I feel the same way about Java allowing dropping types for lambdas.

System.out.println is NOT a static method

I hope you are well. Visiting your channel I have seen your all videos and content are very good but your video SEO optimization is not professional. Perhaps you are busy for managing the channel
