Java didn't copy Linq. It copied Linq syntax. Linq is not just about syntax it's about expression trees or "code as data".

A Linq expression can be translated at runtime to allow the same code to be tranlated to Sql for an RDMS , MongoQuery, or anything else that you write a provider for.

How does Java linq look like?

I think he's referring to the Stream-API

It is the Stream API.

IMO it's completely inferior to LINQ in C#. One of the main reasons being that Java still lacks extension methods, so you're stuck with the methods that are provided for you. In C#, if I want a Dedupe in my LINQ method call chain, I can simply implement it myself.

Annotations are a Java innovation.

Edit: this is not correct. My bad.

C# Attributes were introduced in .NET 1.0. Released in 2002. Betas were available already during 2001.

Java annotations started to be discussed in 2002, with JSR-175, finally delivered with Java 1.5, released in 2004.

So how come it is a Java innovation?

You are absolutely right. My bad.
