How to implement the RemoveLast function in a link list? check my code plz

Question

Hi guys,
How to delete the last element in a user defined linklist. I am using the following code to find the last element of the list. It works fine, but i don't know how to remove that element ...
public Object getRear()
               rear=front;
               while (rear !=null)
                    if (rear.getNext()!=null)
                         rear=rear.getNext();
                    else
                         break; //rear Node found
               if (rear !=null) //list is not empty
                    return rear.getData();
                    return null; //list is empty
     }

Sorry, I missed out on returning the last element:
public Object delRear() {
  // I assume front is an instance field pointing to the first element
  if(front != null) {  // list contains something
    Element  rear, pred;  // I assume you have some type like this
    // determine predecessor of last element
    rear = front;
    pred = null;
    while(rear.getNext() != null) {
      pred = rear;
      rear = rear.getNext();
    if(pred == null)  front = null;  // delete only element
    else  pred.setNext(null);  // delete last element
    return  rear; // return deleted element
  else  return  null;
