In which cases is it preferable to use ArrayList, and in which LinkedList?

ArrayList is preferable when:

• Fast access to elements by index is needed (get operation).
• Main operations are reading and iterating over elements.
• Elements are added at the end of the list.

LinkedList is better suited when:

• Frequent insertion or deletion of elements in the middle of the list.
• Fast access by index is not required (get operation is slower).

Example:

• For implementing queues or stacks, where quick insertion and removal from the beginning or end are important, LinkedList can be more convenient.
• For storing a large number of elements with frequent index access — ArrayList.
