In actuality the definition of Array. So, the collection must be a mutable list.
find is kept around as an alias because it's more intuitive and discoverable for programmers not already familiar with these Linq-style - or functional - methods. We can use sort () and sortDescending () methods to sort lists in Kotlin in ascending and descending order, respectively: val sortCitiesAscending cities.sort () val sortCitiesDescending cities.sortDescending () Copy These methods will use the natural order of the elements and will sort in-place.Your program will be able to create an order, add noodles and vegetables to it, and then calculate the total cost of the order. You will create a food ordering program that uses lists in the Kotlin Playground. find(predicate) and firstOrNull(predicate) are identical in behaviour and find can be considered alias of firstOrNull You will experiment with lists and list operations in the Kotlin Playground. In this lesson, youll learn how to find certain items in a Kotlin list.Watch the entire FREE Kotlin Programming course here: AboutPressCopyrightContact.People who like precise meaning can use firstOrNull, singleOrNull to express the intent. Much like indexOf has well-known semantics, find is also widely recognised as "find first item matching predicate or return null if nothing is found". I think we can undeprecate find and make it an alias to firstOrNull.
While not an official statement, JetBrains' employee Ilya Ryzhenkov describes it as: In this thread from 2014, Kotlin community members and JetBrains staff discuss the merits of the different methods find and firstOrNull:
