Can you explain the differences between ArrayList and other list types in Java?

In Java, ArrayList is an implementation of the List interface based on a dynamic array. The main differences between ArrayList and other lists (such as LinkedList) are:

• Data storage: ArrayList uses an array, which provides fast access by index (O(1)), but insertions and deletions in the middle of the list can be costly (O(n)) because elements need to be shifted.
• LinkedList stores elements as linked nodes, which allows efficient insertion and deletion in the middle of the list (O(1) if the node reference is known), but access by index is slower (O(n)).

Thus, ArrayList is better suited when fast access by index is frequently needed and insertions/deletions in the middle of the list are rare.
