Thank you Daniel for this and the other videos ! Cannot say enough about your ability of simplifying the covered material. Will be recommending the videos to others as well and will also subscribe to the Cats course !

A PROBLEM I faced on start - an error "java.lang.class not found exception" when tried to run Playground.
RESOLVED via these steps:
1. Ensured that the `Playground` class is correctly marked as the main class. - Go to `Run` > `Edit Configurations`> click the `+` button, select `Application`, and set up a new configuration with the main class set to `Playground`.
2. Marked correctly the source directory is correctly marked. Right-click on the `src` directory (or the directory containing your `Playground` class) and select `Mark Directory as` > `Sources Root`.
3. Rebuild the project once again.

Great course! Clear, nicely organised and well-structured, thanks Daniel!

For all people with the error with the library: Both on my Windows as well as on my Mac I had to close and reopen IntelliJ after updating the Global Libraries section in IntelliJ manually.

It didn't prompt me, but plugins was readily available, and Scala was at the top of their list to install in 2023 : )

using vscode instead of intellij. Works also fine.

I wonder if anybody knows a Golang toturial like this Light Speed series?

[quasenerd]

Would you mind to explain the main differences between the Youtube 2-hours course and the Udemy 15-hours course? What am I gonna take from the Udemy course that I would not from the Youtube course?

[dinrash]

scala: Error: Error compiling the sbt component

[arvinflores]

I was planning to watch this 2 hour course of yours then buy your udemy course about Spark&Big Data. You think it is feasible or will I have a hard time? I came from Python and Matlab

edit: nvm I'm having a hard time keeping up, I'll just buy the scala beginner's course too in Udemy lol

[keremkurban]

As a python programmer im having challenges running these scripts. I am getting no Scala SDK in module after installing IJ. I installed latest JDK. What else do i need to do ? Thanks for the videos.

[rahuldas]

hey, just came from the Reddit post. This is fantastic! Literally no one on youtube did a scala video series other than Derek Banas and he didn't use intelliJ for it :(. Can you do one for Swift?

[javiercabrera]

I am getting a Cannot resolve symbol App And Cannot resolve symbol println. What could be causing this?

[tomkers]

The faster and lighter way without rootkits would be to use vscode.

[saikiran]

Could you please tell me how to do this on a mobile ??
