A variable provides a name to a specific piece of memory that contains data you can use in your code. Or, if you are using an IDE like Android Studio or IntelliJ, you can install the Kotlin plugin. In this Kotlin Tutorial, we learned how to check if at least one of the elements in this list matches the given predicate, using Kotlin List.any() function.To execute the Kotlin code snippets demonstrated in this guide, you can use the Kotlin online playground.

Println('Does list2 have at least one element? $anyInList2')ĭoes list1 have at least one element? trueĭoes list2 have at least one element? false Println('Does list1 have at least one element? $anyInList1') We will call list.any() function on these lists, and observe the output in the two scenarios. In this example, we will take two lists: list1 with two elements, and list2 with no elements. Println('Does at least one element in list matches predicate? $anyElementMatchesPredicate')ĭoes at least one element in list matches predicate? trueĮxample 2: Check if List has At least One Element Val anyElementMatchesPredicate = list1.any(predicate) In this example, we will take a list of elements, of type string, and check if at least one of the elements matches the given predicate that the length of string is 3. If no argument is given to any() function, then it returns true if collection has at least one element.Įxample 1: Check if At least one element of List matches Predicate The function returns true if at least one element matches the given predicate. The syntax of List.any() function with a predicate passed to it is

So, the working of any() depends on if an argument is given to it. The Kotlin List.any(predicate) function checks if any one of element in the list matches the given predicate. The Kotlin List.any() function checks if there is at least one element in the list, and returns a boolean value. To check if at least one of the elements of this List satisfy a given condition/predicate, call any() function on this List object and pass the predicate as argument to the function.
