add to end oflinked list java code example

Example 1: adding an element to the end of a linked list java

class Node {
    Object data;
    Node next;
    Node(Object d,Node n) {
        data = d ;
        next = n ;
       }

   public static Node addLast(Node header, Object x) {
       // save the reference to the header so we can return it.
       Node ret = header;

       // check base case, header is null.
       if (header == null) {
           return new Node(x, null);
       }

       // loop until we find the end of the list
       while ((header.next != null)) {
           header = header.next;
       }

       // set the new node to the Object x, next will be null.
       header.next = new Node(x, null);
       return ret;
   }
}

Example 2: how to add to the end of a linked list

typedef struct node{
    int value; //this is the value the node stores
    struct node *next; //this is the node the current node points to. this is how the nodes link
}node;

node *append(node *head, int val){
    node *tmp = head;
    node *createdNode = createNode(val);

    while(tmp->next != NULL){
        tmp = tmp->next;
    } 

    tmp->next = createdNode;
    return head;
}
