What is the equivalent of Java static final fields in Kotlin?

Question

In Java, to declare a constant, you do something like:

class Hello {
    public static final int MAX_LEN = 20;
}

What is the equivalent in Ko

Answer 1

For me

object Hello {
   const val MAX_LEN = 20
}

was to much boilerplate. I simple put the static final fields above my class like this

val MIN_LENGTH = 10

class MyService{
}
