I've been struggling as a JavaScript developer to wrap my head around Java and this video was exactly what I was looking for. I needed someone to connect what I already know in JavaScript with what I'll be using in Java and you did just that! Thank you so much!

[satinek]

Really helpful video! You really have a talent for teaching.

[iiimiiim]

Thank you SO much for making this video!

Thank you so much for this. As a JavaScript first (and mostly only still) dev, I've been wanting to branch out more and dig into other more structured and static languages. This was definitely a very concise introduction to foundational differences between JavaScript and Java, although I feel once I actually get writing some Java, I'll def be smacking my head a bit for awhile haha There is something beautiful about bringing order to the malleable chaos that is JavaScript and then there's having to share a codebase with other JavaScript devs. Java seems like it would be a lot less painful on a larger scale when you've got the ropes down.

The simplest crash course I've seen about java, thanks

[rockNbrain]

Tks, thats what I needed to read clean code

[domtaylor]

Exactly what I was looking for. Underrated video.

[vamshikrishnareddy]

youtube recommended me this video and I was like meh and wanted to watch the first 10 min but ended up watching the entire video. Thank you for explained everything in detail loved it

[gambo]

[robb]

That was awesome! Thanks for this. Great introduction.

[MrJohn]

This was very educational. Thanks for sharing

You can loop the hashmap and get the values for each key.
for(int i = 0;i < studentAges.size();i++) {
String key =


}

This is really great vodeo, It seems that if ypu know typescrpt, switching to java is much ore natural :)

I cannot believe it has only 810 views

[stefanoconsonni]

Thank you so much! It was very helpful

[jetmartin]

I believe you can store different types in an ArrayList (e.g., ArrayList<Object> arr = new ArrayList<Object>();)

[absurdshark]

This was very helpful. thank you so much, I hope you make more fun videos ✨✨

[jetmartin]

You can override methods in JavaScript.

[ingogriebsch]

Is there also such a course available that explains JavaScript to Java programmers? :)

[jpfrolic]

A lot don't get it! Dark screens are difficult to read.
