Learn Kotlin for Spring Development

Java developers who want to move to Kotlin, a language that runs on the Java Virtual Machine, will find a practical path here. The book builds on existing Java experience and covers the core techniques needed to create working applications in Kotlin.

The opening chapter offers a brisk overview of the language, and later chapters return to each topic in more depth. Readers study the essentials of generics, functional programming, the type system, debugging, and unit testing. Free online appendices extend the material to Spring Boot applications, data persistence, and microservices.

Along the way, the book covers functions, types, collections, generics, and classes, along with higher-order functions. It also shows how to apply Kotlin inside Spring Boot, how to add Hibernate for persistence and data access, and how to put Kotlin's functional features to use.
