Is the size of a LinkedList fixed or can it change dynamically?

The size of a LinkedList is not fixed and can change dynamically.

A LinkedList is a data structure consisting of nodes, each containing data and a reference to the next (and, in the case of a doubly linked list, to the previous) element. When elements are added or removed, the list grows or shrinks accordingly.

For example, in Java (and Android), the LinkedList class implements a dynamic list where elements can be added or removed at any time without the need to specify the size in advance.
