Answer 2

It's the arrow thingy
(paramsHere) -> {code here;}
You can make semi functions with it, like compare function to sort elements the way you want.
Here's a code where I use them quite a bit as an example. getOperation returns a lambda expression which I use to get results for each element in range later on.
