New to pattern matching, I liked how the presenter explained it using real-world examples, before demonstrating how it works with instanceof and switch. Also, how it decreases the cognitive load.

[andrealves]

Thank you for your explanation and really good examples of Switch Statements and Sealed Classes Mala.
Before watching your video, I was having a hard time to think of a scenario which I would use sealed classes.

Just became a proud IntelliJ Customer. Love these videos!

Straight forward explanation, love it!

The demo of code reduction at 8:32 is done in under 60 seconds! I'm an experienced Java developer but I had to review it several times. Then there is the result - it makes maintenance harder. Someone looking at it for the first time would have to expend a lot of mental effort to understand what it does, instead of taking it in line by line as its read.

It is really a great explanation kudus to you !! I started following you.

[atellezfx]

Great explanation! 👍, I have a question, How do you create that kind of comments? (the one that appears in 06:27 "Pattern matching for instanceof")

[sandeepthakur]

Nice work can you provide code used for examples as github repository

Java 17 has no JRE so how can I run a Swing program outside of Intellij ?

[sushilraikwar]

I hope java also upgrade as like python, scala programing language. Then jave more use in machine learning in data science. Then jave beat to scala in spark (big data) . Stop support of old version till java 16 then now start support 17 to upcoming version then production and software company move on java 17 and upcoming version. Most of java developer love to java that is why they want use java in data science, machine learning, big data(hadoop, spark) as like python, scala.

How come my IntelliJ IDEA doesn't convert if to switch? Does anyone know?

[lgoptimusv]

Thank you very much for the video. It’s a bit too long for me.

[mohammedabraruddin]

i would love to see the tutorial in dark mode intellij

[alexei]

Why project Loom is not include in Java 17 ?

[jhonathanmartini]

that's too much updates every 6 months you are making it tedious on engineers
