ArrayList and LinkedList are two commonly used classes in the Java Collections Framework. Both implement the List interface and allow duplicate elements while maintaining insertion order. However, they differ in how data is stored and how operations are performed. ArrayList ArrayList uses a dynamic array to store elements. It provides fast access to elements using indexes and is suitable when data retrieval is performed frequently. Features of ArrayList Uses a dynamic array internally. Maintains insertion order. Allows duplicate elements. Fast random access using indexes. Slower insertion and deletion in the middle of the list because elements need to be shifted. LinkedList LinkedList uses a doubly linked list to store elements. Each element is stored as a node containing data and references to the previous and next nodes. Features of LinkedList Uses a doubly linked list internally. Maintains insertion order. Allows duplicate elements. Fast insertion and deletion operations.…
