Why Kotlin is the better Java and how you can start using it
summary
Kotlin claims fewer null pointer exceptions by enforcing compile time nullability and the Elvis operator, generates boilerplate automatically via data classes (getters, equals, hashCode, toString), and adds behavior to libraries with extension functions. Demos show smart casts and string templates, a three year production Kotlin codebase reads easier after a Java-to-Kotlin team migration, Kotlin targets JVM/Android (preferred for Android since 2019) and interoperates with Java at project level though not within a single source file.
