java - Creating and chaining LinkedList in for loop -

i trying create new linkedlistnode object parse through char[] in reverse. want link these

    char[] totalnum = (total + "").tochararray();     (int = totalnum.length; > 0; i--) {         linkedlistnode sum = new linkedlistnode(totalnum[i]);         sum.next = null;     } 

here linkedlistnode class:

public class linkedlistnode {     int data;     public linkedlistnode next;      // constructor     public linkedlistnode(int newdata) {         this.next = null;         this.data = newdata;     } } 

i wondering how can go doing this. new java has gotten me stumped! know should create new linkedlistnode object in each iteration far have gotten

public class linkedlistnode {     int data;     private linkedlistnode next;      public linkedlistnode(int data) {         this.data = data;     }      public void setnext(linkedlistnode next) {         this.next = next;     }      public linkedlistnode getnext() {         return next;     } }  char[] totalnum = (total + "").tochararray(); int length = totalnum.length;  linkedlistnode tail /*or 'head', whatever suits you*/ = new linkedlistnode(totalnum[length - 1]); linkedlistnode newnode; linkedlistnode previousnode = tail;  (int = length - 2; >= 0; i--) {     newnode = new linkedlistnode(totalnum[i]);     previousnode.setnext(newnode);     previousnode = newnode; }
