![]() ![]() ![]() It allows dynamic resizing of the list, and provides various methods for adding, removing, and manipulating elements in the list. In Kotlin, we have special functions to create arrays of primitive types: val bytes byteArrayOf ( 42 ) val shorts shortArrayOf ( 42 ) val ints intArrayOf ( 42 ) val longs longArrayOf ( 42 ) val floats floatArrayOf ( 42.0f ) val doubles doubleArrayOf ( 42. The only difference is that we donât specify the value for it since it will only be mapped by that. In Kotlin, an ArrayList is a resizable list implementation backed by an array, similar to the ArrayList in Java. The sortedWith() method takes a comparator compareBy that compares. Val user3 = User("Dave", 34, givenList_whenConvertToMap_thenResult(). In the above example, to sort the list with the property, we used lists sortedWith() method. Its also extended by to be used when a collection that allows for item modification is needed. Val user2 = User("Sara", 25, listOf("Chess")) Furthermore is an interface implemented among others by . The sort() method modifies the list in-place, and a sorted() built-in. Kotlin offers the convenient toMap method which, given a list of complex objects, will allow us to have elements in our list mapped by any values we provide: val user1 = User("John", 18, listOf("Hiking"))
