No need to apologize, everyone starts somewhere. Linked lists can be reversed by changing the next to a previous node using iterative or recursive methods. Below you can find both methods: **Iterative Method:** ```java public Node reverseIteratively(Node node) { Node previous = null; Node current = node; Node next = null; while (current != null) { next =; // store the next node = previous; // reverse the link previous = current; // move the step ahead for the next iteration current = next; } node = previous; return node; } ``` Here `Node` is the structure of a single node, which might look like this: ```java class Node { int data; Node next; Node(int d) { data = d; next = null; } } ``` **Recursive Method:** ```java public Node reverseRecursively(Node node) { if (node == null || == null) { return node; } Node remaining = reverseRecursively(; = node; = null; return remaining; } ``` In the recursive method, we recursively call the function for `` until we reach the end of the list. Then, we change the link from `next` node to `current` node for each pair of nodes and continue this until all pairs are linked in reverse. Remember you need to set both `` and ``. The former is to change the link direction, the latter is to avoid a cycle. Hope this helps! Let me know if you need further information. Understanding linked lists and their manipulation is an important step in improving your knowledge of data structures and algorithms in Java.
