Var planets = arrayListOf("Mercury", "Venus", "Earth", "Jupiter") In the below example, we are checking if ArrayList contains the planet Pluto. We can use contains method to check if ArrayList contains the element or not. In the below example, we are using add method to insert Jupiter in between the ArrayList. This accomplishes adding element to that location.
We can use add method, specifying an index where to add the element followed by the element. Jupiter Adding element to middle of an ArrayList In the below example, we are using add method to add Jupiter to the end of planets list. We can add elements to end of an ArrayList using add function call.
Saturn Adding element to end of an ArrayList Planets.addAll(listOf("Jupiter", "Saturn")) In the following example, we are adding more planets to our list of planets using addAll method. We can use method addAll to add a list of elements to array list. Pluto Adding elements to an existing ArrayList In the following example, we are iterating through array list of planets and printing each planet. We can use for loop to iterate through an arraylist in Kotlin. Var planets = arrayListOf("Mercury", "Venus", "Earth", "Pluto") In the following example, we are creating an arraylist with list of planets and then printing the arraylist. We created String theory of empty cosmos below. We can create an array list using arrayListOf builtin function. In this tutorial we will go through features of ArrayList in Kotlin. This is how my provides implementation for MutableList interface in Kotlin. Import .ansactionĬall.respond(HttpStatusCode.InternalServerError, ex.localizedMessage) This is how my file looks: package routes To be registered automatically, class 'ArrayList' has to be and the base class 'List' has to be sealed and register the serializer for 'ArrayList' explicitly in a corresponding SerializersModule.
Everytime I call the endpoint I get Class 'ArrayList' is not registered for polymorphic serialization in the scope of 'List'. I'm trying to get started with ktor and exposed and I created this file that just retrieves films from a postgresql db but I can't seem to make it work.
