I was a little lazy with this:
I made a function to get all the nodes in the linked list as an array;
then for reverseLinkedList ,
I iterated through that array,
setting .next for each node to be the previous node
and I returned the last node in the array.

I had to add in checking whether a node is null to prevent errors.

my code

I made functions to get the length of the linked list, and to make it into an array of nodes.

  public static int getSize(Node starting) {
    if (starting == null) {
      return 0;
    int count = 1;
    Node current = starting;
    try {
      while (!( == null)) {
        current =;
    finally {
      return count;

  public static Node[] nodeArray(Node head) {
    int length = getSize(head);
    Node[] list = new Node[length];
    if (length == 0) { return list; };
    list[0] = head;
    Node current = head;
    for (int i = 1; i < length; i++) {
      current =;
      list[i] = current;
    return list;

  public static Node reverseLinkedList(Node linkedList) {
    Node[] nodes = nodeArray(linkedList);
    int length = nodes.length;
    if (length <= 1) {
      return linkedList;
    Node previous = nodes[0]; // linkedList = null;
    Node current;
    for (int i = 1; i < length; i++) {
      current = nodes[i]; = previous;
      previous = current;
    return nodes[length - 1];

This was my best go, just started dipping into Java so may not be very effective.

public class Reverse{

  public static Node reverseLinkedList(Node linkedList){
    if(linkedList == null){
      return null;

    Node currentNode = linkedList;
    int listSize = 1;
    while( != null){
      currentNode =;
    Integer[] newList = new Integer[listSize];

    currentNode = linkedList;

    for(int i = listSize-1; i >= 0; i--){
      newList[i] =;
      currentNode =;

    Node newLinkedList = Node.makeLinkedList(newList);

    return newLinkedList;

  public static void main(String[] args){
      Integer[] testArr = {4, 8, 15};
      Node testNode = Node.makeLinkedList(testArr);
      System.out.println("Original Linked List");
      Node reversed = Reverse.reverseLinkedList(testNode); 
      System.out.println("Reversed Linked List");
