I had considered iterables for a while but wasn’t sure how to join an iterable. After some research and experimentation, I found out that it is not difficult to do at all! In this post, we’ll discuss how to join an iterable in Java and Scala. The first step is to create a new iterable. This can be done in Java by creating an instance of java. util.ArrayList and calling the constructor with no parameters, or in Scala by using Array(Nil) where N is any natural number greater than zero (0). The next step is to call either flatMap() on a function that takes two arguments: some element from your iterable and returns another Iterator for it; It’s also possible to use map(). In this post, we’ll see how both methods work when joining an array list together into one long list as opposed to separating them into sublists. First, let’s take a look at the `flat map implementation in Java code – note
