Does Kotlin have primitive types?

Question

Does Kotlin have primitive types?. When I declare the variable: val myAge: Int = 18 then the myAge variable stores the actual values is 18

Answer 1

Short answer - yes and depends on the declaration.

val myAge: Int = 18           // this is primitive
val myAge2: Int? = 18         // this is not
