Interoperability between Java and Kotlin collections

In this section, we will discuss the interoperability between Java and Kotlin collections. While we now understand the differences and similarities between the two languages, you might still have questions about how to work with mutable versus immutable collections, handle nullability, or convert collections between the languages. We’ll address these concerns and explore practical examples that demonstrate seamless integration in mixed-language environments.

First, we will talk about how Kotlin automatically handles the conversation between Java and Kotlin collections. When a Java method expects a Java collection, you can pass a Kotlin collection and vice versa.

Remember that since Kotlin is designed to be fully compatible with the Java ecosystem, this means that you can use Java collections in your Kotlin code.

Another important consideration is understanding the differences in mutability and nullability. While...
