Choosing Between ArrayList and LinkedList in Java: A Comparative Analysis

ArrayList and LinkedList are two commonly used list implementations in Java. Both implement the List interface but differ in how they store elements. ArrayList uses a dynamic array to store elements, making it efficient for random access. In contrast, LinkedList uses a doubly-linked list, which is better suited for frequent insertions and deletions.

Here’s an example of using ArrayList and LinkedList:

import java.util.ArrayList;
import java.util.LinkedList;
import java.util.List;

public class ListExample {
    public static void main(String[] args) {
        List arrayList = new ArrayList<>();
        List linkedList = new LinkedList<>();
        arrayList.add("Apple");
        linkedList.add("Banana");
    }
}
            

For applications that require quick access to elements, ArrayList is a better choice. However, LinkedList is more efficient when frequent insertions or deletions occur, especially at the beginning or middle of the list. Choosing between the two depends on the specific use case.
