Can "Kotlin" be able to surpass "Java"?

Answer 1

yes in case of android it good than java

Answer 2

Google recently accepted kotlin as an official language for android development, but Java is still used for SO many things, that it's not gonna replace Java 100% probably ever. However, kotlin is pretty new, and is constantly evolving, so if you want to learn a new language, then kotlin is not a bad choice.
