Answer 1

You can use following code in Kotlin.

var callback:Callback = object:Callback() {
  fun getCallback(serverResponse:ServerResponse) {
  }
}

var callback:CallBack = object:CallBack { override fun callBackFun(obj: Any, function: () -> Unit) { } } – Uncurl

Answer 2

var callback:Callback = object:Callback() {
  override fun getCallback(serverResponse:ServerResponse) {
  }
}

var callback:Callback says that the variable type is a Callback

object:Callback() { } is an anonymous class. It has no name when created, before being assigned to var callback. It's similar to the new Callback() code.

override replaces @Override

fun indicates that it is a function

I think it's not an anonymous function, rather it's an anonymous class, which implements the Callback interface. Actually the overridden function getCallback has a name, 'getCallback', which is not anonymous. – Bwana
