This document compares Kotlin and Java programming languages. It discusses what Kotlin and Java are, their key features and parameters for comparison such as compilation time, null safety, lambda functions, and community support. While Java has a larger community and is more established, Kotlin has advantages like easier learning curve, concise syntax, and null safety. The document also questions whether Kotlin will replace Java in the future.
