Perhaps the easiest example, and one of the most interesting, of interoperability between Java and Kotlin is the ability to quickly convert Java code into Kotlin code with a single IDE command. Technically, this is more of a feature of the IDE, but as powerful tooling is an important aspect of the viability of a language, it's worth exploring how this conversion process works.
By converting existing Java code in this way, you can help to do the following:
- Introduce Kotlin into a Java code base in places where existing tests can validate no regressions
- Understand common Kotlin features and idioms by comparing them to Java code you already understand
- Allow developers to quickly start using Kotlin without a steep learning curve
All of these traits can make the Kotlin learning and adoption process much easier and more enjoyable. In this section,...
