What are the characteristics of the Java linked list data structure?

The characteristics of Java linked list data structure are:

1. Dynamic size: The size of the linked list can be adjusted dynamically according to the needs, without the need to specify a size beforehand.
2. “High efficiency in insertion and deletion: Due to the nature of linked lists, the efficiency of inserting and deleting elements is relatively high, as it only requires modifying the pointers of nodes.”
3. Random access efficiency is low: the elements in the linked list are not stored in contiguous memory addresses, so it is not possible to directly access elements by index and instead requires traversing from the beginning.
4. Memory consumption is higher: Compared to arrays, linked lists require extra storage for node pointers, resulting in relatively larger memory space usage.
5. High flexibility: Linked lists allow for convenient insertion and deletion of elements, making it suitable for scenarios with frequent insertion and deletion operations.
