One effect of the unpacking syntax (see Item 5: “Prefer Multiple-Assignment Unpacking over Indexing”) is that it allows a Python function to seemingly return more than one value. For example, say that I’m trying to determine various statistics for a population of alligators. Given a list...

In this tutorial, we’ll discuss whether the collect() method can return a null value. 2. Introduction to the Problem The question, “Can Stream‘s collect() method return null?” has two meanings: Must we perform the null check when we use this method with standard collectors? Is it ...
