Hi,

Thanks for sharing this list of top programming language for mobile app development in 2021.

For mobile app development kotlin and java are one the top languages picked by developers.

If you want to choose between Kotlin and Java, my vote goes with Kotlin.

Kotlin combines features of both object-oriented and functional programming, whereas Java is limited to object-oriented programming. Kotlin allows users to create an extension function while Java doesn't offer any extension functions.

But both have their own benefits.

If you want to compare between Kotlin vs java, read this blog to know more.
