Interoperability, Gradle, and Maven

Transitioning from Java to Kotlin is not just a change in syntax but an evolution towards more modern and efficient programming. In this chapter, we will focus on three fundamental pillars for developers who want to integrate Kotlin into their existing projects or start new projects leveraging the Java ecosystem: interoperability, Gradle, and Maven.

One of Kotlin’s greatest advantages is its seamless integration with existing Java code. This interoperability between Kotlin and Java is a game-changer for developers, enabling them to leverage the extensive ecosystem of Java libraries, frameworks, and tools without disruption. The interoperability feature allows for a hybrid code base where Kotlin and Java can coexist, interact, and complement each other efficiently. This capability ensures that developers can call methods, instantiate classes, and use Java libraries directly from Kotlin code, thereby preserving their established workflows...
