Summary

This interactive chapter that introduced some of the commonly used operations on objects and collections was only a glimpse to demonstrate some of the expressiveness and powerful constructs of Scala.

In the next chapter, we are going to increasingly blend Scala with an existing standard Java web application. Since there are so many ways by which one can create a standard web application, combining some of the many frameworks and database technologies available, irrespective of whether they involve Spring, Hibernate, JPA, SQL, or NoSQL, we will take the straightforward path of some of the well-established JavaEE tutorials.
