Summary
In this chapter, we explored the essential concepts of Collections and Sequences in Kotlin and compared them with their Java counterparts. You learned about key collection functions such as filter, fold, groupBy, and maxBy, along with their concise and expressive implementations in Kotlin. We discussed the advantages of Kotlin collections, including their immutability, declarative syntax, and functional programming capabilities, which simplify complex data manipulation tasks.
In addition, we delved into sequences and their lazy evaluation model, which optimizes memory usage and processing for large datasets or long pipelines. By comparing sequences to Java Streams, we highlighted their superior syntax, reusability, and integration with Kotlin’s type system. These comparisons equipped you with the knowledge to choose between collections and sequences depending on performance needs and application context.
Finally, we addressed the interoperability between Java...
