This is because it uses the concept of an array for searching elements based on the index while LinkedList traverses through every element.
ArrayList is the best operation for searching elements since performance is O(1) while comparing with LinkedList that has O(n).It is always a good option to use LinkedList for frequent insertion and deletion operation since the performance is faster which is O(1) when comparing with ArrayList which is O(n).("Elements in LinkedList" + states) Įlements in ArrayList: Įlements in LinkedList specified beyond the fact that adding an element has constant amortized. The details of the growth policy are not. As elements are added to an ArrayList, its capacity grows automatically. They present a fixed length which is not possible to be altered during runtime. In this example, we create an ArrayList of String type to store city names and create a LinkedList of String type to store state names. the size of the array used to store the elements in the list. Arrays are strongly-typed data collections of the same type. The iterator and listiterator are fail-fast which means it throws ConcurrentModificationException if the list is modified after it creates the iterator.Maintains insertion order which means it displays the elements in the same order it inserts.
