Lambda implementation of interface in kotlin

Question

What would be the equivalent of that code in kotlin, nothing seems to work of what I try:

public interface AnInterface {
    void doSmth(MyClass inst, int nu         


        

Answer 1

If AnInterface is Java, you can work with SAM conversion:

val impl = AnInterface { inst, num -> 
     //...
}

Otherwise, if the interface is Kotlin...

interface AnInterface {
     fun doSmth(inst: MyClass, num: Int)
}

...you can use the object syntax for implementing it anonymously:

val impl = object : AnInterface {
    override fun doSmth(inst:, num: Int) {
        //...
    }
}
