Learning Scala Programming

Packaging and importing

One of the important aspects of object-oriented programs is how we define modular, reusable, and hierarchical structures. We're allowed to put all the code that we write, constructs like classes, traits, and objects, in some particular package. By using packaging and visibility rules, we can make our code more to reason about, means to expose some method to other classes or  and we get structured and modular code as an added advantage. There are a couple of ways you're allowed to write package statements in Scala; we'll take a look at those.
