Kotlin. How to get specific subclass of sealed class?
I'm using kotlin sealed class. And I need to retrieve specific subclass. My sealed class:
sealed class Course(
val type: Type
) {
data class ProgrammingCourse(val name: String, val detail: String) : Course(Type.PROGRAMMING)
object LanguageCourse: Course(Type.LANGUAGE)
.....
}

fun getCourse(): Course {
if(...)
return Course.ProgrammingCourse("test", "test")
else
return Course.LanguageCourse
}
