Passing a Scala function to a Java 8 method
The following Scala code works and can be passed to a Java method expecting a function. Is there a cleaner way to do this? Here’s my first pass:
Why were default and static methods added to interfaces in Java 8 when we already had abstract classes?
In Java 8, interfaces can contain implemented methods, static methods, and the so-called “default” methods (which the implementing classes do not need to override).

How the Stream.filter() method works?
I know how the lambda expresion works and I know it is an argument for .filter() that establish the criteria to filter with. But I don’t get how .filter() uses the argument, in this case a lambda expression, because .filter() does’t have an implementation or at least require one at compile time. I search for this unknown implementation in the Oracle’s site but there are just a few words explaning how it works and no code at all.

Java Streams API Documentation
Currently learning Java so this may be a question resulting from lack of understanding of Java (while also learning Streams API)
Is it a sane thing to return Streams wherever we would normally return Collections?
While developing my API that is not tied to any legacy code, I often find myself writing methods that are purely Streams pipeline terminated by collecting the results. Like this one:
