Select the correct version of the method deleteBack that deletes the last value (the value at the back
of the list) and returns the deleted value. If the list is empty, your method should throw
a NoSuchElementException.
Assume the LinkedIntList class as defined below:
public class LinkedIntlist {
private ListNode front; // null for an empty list
public int deleteBack () {
ListNode current=front;
int rdata=0;
if (front==null) throw new NoSuchElementException ();
if (front.next==nul1){
rdata=front.data;
front-null;
return rdata;
else {
while(current.next.next!=null)
current=current.next;
rdata=current.next.data;
current.next=null;
return rdata;
