So exciting to see the Java evolution! And as Venkat mentions in the end, imagine having things like destructuring in Java, dear lord, just can't wait to see it.

I was waiting for several minutes for you to spot the superfluous "r" in "interger", and was very happy when you finally removed it.
Just for you to undo 20 seconds later and put it back in again :D

can you ask Venkat to use some IDE which uses syntax highlighting.. this will make code reading a lot better.. Presentation is really good.

It is very interesting and push to have more elegance in coding. Perhaps it missing something on generic types.

How pattern matching is going to handle dynamic code and scenarios that can occurs with OSGi?

Nice presentation. However, you should be aware most of the examples presented here violate Liskov substition principle. I hope I'll never see switch cases differentiating between interface implementations.

Why is this called pattern matching ? I thought pattern matching was related to regex

I do not understand why Venkat encourages us not to use default when an unexpected value is received. I always throw an IllegalArgumentException. That behaviour is future proof.

Dr Subramaniam might not do Scala any more, but I guess he will admit that Scala's pattern matching is the best and although Java's pattern matching is nice, it's like a joke compared to the Scala one.
