I have been coding in scala for the last 4 years, this was the best tutorial i have found. Thank you

So 
* Java "interface" is "trait" in Scala
* "Implements" is "with" in Scala
Just testing few methods in my local.
* I can write multiple apply by overriding with number of arguments and access it the same way you have explained.

Love the case class
❤

Wow the Case for catching exception avoids writing multiple catch blocks for every type of exception. That's nice.
This is like simple case statements.

I have joined the company and here all the spark jobs are in Scala. I am watching your videos, they are really helpfull.

scala is truly amazing, but I will have to come back to this tutorial when i learned my OO and functional paradigms more better. Subscribed.

This is soooo useful content. Pure Gem! And Daniel you are a great teacher! The content quality is very good, truly jam-packed.. and a one stop shop to learn. I am surprised why you have so less views, likes and subscriptions..

You are rocking buddy, Thank you very much for your efforts !. Best part is, these videos are too good for a experienced programmer and can relate things easily.

24:24 "trying to catch an exception in c++ is like trying to shoot yourself with a chicken wing" LOL

[UpTown]

Crystal clear explanations, very helpful content in a short time you really Rock man! Thank you!

[alexpopa]

Hi Daniel,
Really nice series, appreciate a lot the time and effort you spend to create this extremely useful content. Keep up the awesome work!

[Wooder]

Soo i am starting my career with programming and this seem so advanced, but i kind of like it. Really well done.

[kirillvourlakidis]

Java most certainly has (and always had) anonymous classes, that's why Java8 lambdas are backwards-compatible.

this series is just awesome.... thanks

Thank you so much! Exactly what I needed :)
