Spring 5.0 By Example

Wrapping it up

Now, we can use the basics of the Kotlin language. We saw some examples and practiced a little bit.

We looked at the main concepts of Kotlin. We have learned how data classes can help developers to transfer data between application layers. Also, we learned about singleton and companion objects. Now we can try to create a real project with the pretty new support from Spring Framework.

In the next sections, we will create a project using the Kotlin language, for now, we can forget about the Java language.
