![]() In functional programming, functions are treated as first-class citizens, meaning that they can be bound to names (including local identifiers), passed as arguments, and returned from other functions, just as any other data type can. It is a declarative programming paradigm in which function definitions are trees of expressions that map values to other values, rather than a sequence of imperative statements which update the running state of the program. In computer science, functional programming is a programming paradigm where programs are constructed by applying and composing functions. Val mutableList = mutableListOf(1, 3, 9, 16)Ĭoncluding this introductory tutorial to Mutable List in Kotlin, we have covered only basic topics like creating, adding an element and removing an element.For subroutine-oriented programming, see Procedural programming. In the following program, we will create a mutable list of integers, and remove the element 9 from the mutable list using remove(element) function. The syntax to use remove() function with element is MutableList.remove(element) The first occurrence, if any, of this specified element will be removed from this mutable list. To remove an element from a Mutable List, call remove() function on this mutable list and pass the element. ![]() In the following program, we will create a mutable list of integers, and add elements to it using add(element) and add(index, element) functions. The syntax to use add() function with specific index and element is MutableList.add(index, element) The syntax to use add() function with element is MutableList.add(element) ![]() We can also specify the index, at which the element has to be inserted. The new element will be added at the end of the list. To add an element to a Mutable List, call add() function on this mutable list and pass the element. ![]() In the following program, we will create a mutable list of integers. The syntax of mutableListOf() function is fun mutableListOf(vararg elements: T): MutableList To create a mutable list in Kotlin, call mutableListOf() function and pass the elements to it. ![]()
