Optionals In Java - Simple Tutorial

thanks

"orElse, It almost sounds like a threat." I laughed at this more than I should have. 😂

Wow John didn't know you were so tall 😮

You are the BEST on these streets.

Schrodinger's object

The best is the final .. advice where to use, generally in return of funciona, not every where creating a mess.

The cat 😂....nice video.... What video editor do you use Sir?

Schrödinger’s Optional

Hello mr jhon .
Thanks for your teaching video 🎉🎉🎉

hahaha ,.. u have a cat in real ,.. so cute , pretty .. Now i got to know Why cat object is there in many video. Give me this optional<cat> to me .. orElse ..

Great job 🙏

Can't resist writing a review, I am preparing for a job as a developer and chose Java as my technology, I have been learning since 4 months now, I was completely devastated and lost few days back as I am not getting any calls for the interviews, luckily discovered your channel and since then I have been going through all the concepts again from your videos, it's just making me so much more confident and stronger, your energy is just pure GOLD!

All the topics have been explained crisply.

Hope I'll soon land a good offer!

Lots of love from India!
❤❤❤❤

Thanks! Direct to the point, it worth all 16 minutes. If I could give 100 likes I will ask why I can't give 1,000

nice, thank you

Love that desk setup, could you do a video about your desk setup? And maybe other stuff as well, such as your favorite IDE, text editors etc.

make a video on StringUtils

John is the best

You know how I am certain this is the best Java channel? I have no interviews to crack, I have no exams to clear and I'm still here learning because it just is explained in such an interesting, problem-solution kinda way.
Brilliant work, John!

This is pure gold, thank you so much!

Very cool, thanks for sharing this information -- just to be nitpicky -- would negative 1 not be a better age to fallback on instead of 0? Kittens can be of age 0 for example -- my comment is less about the technicalities of feline lifespans and more about if in Java- is -1 is an more idiomatic way to express a fallback number for a value that could be 0 OR > 0? For example this is the case in JS where methods like indexOf will return -1 to express that the searched value doesn't exist at any index. OR is it that in java specifically that -1 has a specific integer type that would have complicated your video and been outside of the scope of the subject you were discussing?

Loved your explanation with Cat :) as I am a cat person

Schrodinger's cat

You didn't call it schrodingersCat, my disappointment is immeasurable and my day is ruined.


But otherwise great tutorial xD

Great explanation John

Absolutely brilliant teaching style.

Why not tell the truth? Why no tell that we stall Undefined from the JS?

6' 5''? Didn't know I was learning from a giant.

why don’t we have something like this obj.isPresent().get().orElse(“do something”). ??

Awesome

thank tho i will never use it in my carer

this is so amazing
as backend engineer, I 100% agree
thanks a lot

guard keyword should also be introduced in Java to handle optionals in a systematic way…

I would risk a Code Review bollocking to have called the Optional Variable schrodingersCat.

Thank you, this video has helped me immensely.

Alright I've had enough of you cooking I'm subscribing 🥵

Fred is a really huge cat

This is why I like C#, you just simply cat?.GetAge() ?? 0

Idk if I learned something or if I was threatened subliminally?

Either way, it stuck. Thanks!

I m surprised there is no comment on the cat and the box ? that was the best part

epic explanation with the cat in the box it was so funny!

big WOW

thank you :)
