How can you move to the next element in a LinkedList data structure?

In the data structure LinkedList, each element (node) contains a reference to the next element. To move to the next element, you need to access the next field of the current node. For example, if you have a reference to the current node currentNode, the next element will be accessible through currentNode.next.

Example in Java for a singly linked list:

class Node {
    int data;
    Node next;
}

Node currentNode = head; // head is the first element of the list
if (currentNode != null) {
    Node nextNode = currentNode.next; // move to the next element
}

If using the standard LinkedList from Java Collections Framework, you can use an iterator for iteration:

LinkedList<String> list = new LinkedList<>();
Iterator<String> iterator = list.iterator();
while (iterator.hasNext()) {
    String element = iterator.next(); // move to the next element
}
