You can do Better with Kotlin
summary
Kotlin claims concrete wins: concise data classes that generate equals hashCode to cut boilerplate, zero-overhead nullable types with ? and the Elvis operator to move null errors to compile time, and extension functions used to implement toast and startActivity helpers that compile to ordinary static Java methods. Tooling lives in IntelliJ/Android Studio, Java interop works via class files and a small runtime library (low method count), and an automatic Java→Kotlin converter eases migration.
