I feel like there is an important piece missing here, which is the whole reason to have Optional instead of nulls in the code -> optionals are visible in the typesystem. You immediately know if certain function might return "empty" value and you have to handle it explicitly in the code. Nulls in the other hand are "invisible", just from looking at function signature you don't know if it might return null or not.

im java developer 15 yrs and thats best clever explanation of Optionals

I don't know what magic this is but just this month i started as a working student for backend development. Two of the things i don't know yet but of which there is a lot in my company's code are streams and optionals - so thanks for making your last two videos exactly about those things, the last one already helped me a lot!

I watched video about same topic from Coding with John channel and I must say that he have the better desk.

I'm so glad found you on LinkedIn Learning! Love your content, so helpful for a Junior Java Developer like me! Thank you so much!

I actually didn’t know Java had optionals before watching this video 😅 pretty neat!

[a.koomson]

The video is both engaging and informative. I Like it. Is there a situation where you wouldnt use optionals? I cant think of one...

[prodsg]

could you do some vedio about spring security and thanks for your efforts😊.

Why not to try return String type of method? Then we dont have to use optionals?

Hi, a little question, in your opinion, the best choice to work with android and new applets is Java or Kotlin and why? Happy coding!!! Greetings from Colombia ;)

[fernandorg]

Good job bytes, can I ask you a question? how many languages do you know? :) and keep on rolling!!

[sonxuannguyen]

Hi, which cloud provider (AWS, Azure, GCP) do u or your company often use for Java Spring applications?

[cristianscript]

that's awesome how about javascript?

[adeshmishra]

I know this question is quite absurd but I want to know the reason of learning Java now, Since we have many great programming languages like Python, JavaScript, C++ etc.
Plzz reply ..

She said the F word. I am scarred for life.

Blondie, you don't need to write "System.out.println..", just "SOUT" and press tab 😉
