Constructor in kotlin-CodePudding

i'm wondering is it okey to do something like this in Kotlin?

Java:

   public class DemoSuper {
        private int a;
        private int b;
    
        public DemoSuper(int a, int b) {
            this.a = a;
            this.b = b;
        }
    }

Kotlin.

class DemoClass(
        private val a: Int,
        private val b: Int
) : DemoSuper(a, b)

Basically, I want to call the Java constructor DemoSuper from Kotlin primary constructor DemoClass. I could use the super keyword in Java, but in Kotlin is it possible to do it like this?

Tnx.

CodePudding user response：

Yes, that's exactly the way you do it. Except if DemoSuper also has getA() and/or getB(), you should remove private val from a and/or b because it'll inherit the properties.
