You can use either.

Answer 3

If you notice most of the official Android Development updates especially for Android Studio, are geared toward Kotlin, not really Java. Especially with the fact that Android is trying to ditch XML and use Jetpack compose which is Kotlin as well.
I am unfortunately not sure what Prashanth Kumar means by syntax sugar, because whatever you can use in Java, you can use in Kotlin as well, it's just less verbose. Less verbosity and boilerplate code doesn't mean syntax sugar.
