Modifying a linkedlist

Question

I have to make my own implementation of a linkedlist. I know for methods like add, delete, etc, I can do this:
create a new node and set it to head:
Node temp = head
Say head has these attached to it:
[“a”] - [“b”] - [“c”]
Then would temp look like this?:
[“a”] - [“b”] - [“c”]
I know that to add an node to the end, I can loop through the linkedlist until null:
Node newNode = newNode(data)
while (temp.next != null) {
temp = temp.next;
}
temp.next = newNode
But wouldn’t the linkedlist look like this because I’m setting a new next each time?:
[“c”] - [“e”]
This has made me confused. I assume I need to modify the original linked list and get:
[“a”] - [“b”] - [“c”] - [“e”]

thank you, cleared my confusion!
