That means a list element of a List object does not have to be boxed before the element can be used, and after about 500 list elements are created, the memory saved by not boxing list elements is greater than the memory used to generate the class implementation. In other words, removes Make a list of the ingredients you need to bake the cake. specified collection (optional operation). The List interface provides two methods to efficiently insert and remove multiple elements at an arbitrary point in the list. The element's index is used in the logic of the predicate function.

List (abstract data type) In computer science, a list or sequence is an abstract data type that represents a finite number of ordered values, where the same value may occur more than once. It implements the IList generic interface by using an array whose size is dynamically increased as required. b. : an official roster : roll. [from early 17th c.] the steady wind listed the ship.
