Kotlin was designed to be a better, more modern language than Java while remaining fully interoperable.
Kotlin's type system distinguishes between nullable and non-nullable types at compile time to prevent null pointer exceptions.
Data classes automatically generate getters, setters, equals(), hashCode(), and toString() methods to simplify POJOs.
Extension functions allow you to add new methods to existing classes without inheriting from them, avoiding utility classes.
String templates provide intuitive string formatting, while smart casts automatically handle type casting after an `is` check.
Java still has features not present in Kotlin, such as checked exceptions, primitive types, and wildcard types.
Kotlin and Java code can coexist and call each other within the same project, though with some limitations like null safety.
Developers can learn Kotlin through interactive exercises like Kotlin Koans, books, and by building backend or Android applications.
Migrating a Spring Boot project can be done incrementally, and convincing a team involves focusing on long-term benefits like code stability.
While Java's community is larger, Kotlin leverages the same JVM ecosystem and is unlikely to be fully matched by Java due to legacy constraints.
