Can someone explain the code below? Is .next an operator in java that pushes the pointer to the next node in the linked list?
Node E < -- type node?
public E dequeue ( ) throws EmptyQueueException {
if (isEmpty ( )) {
throw new EmptyQueueException (”Queue under flow”) ;
else{
if (end==front.next) // Special case , dequeue single element in queue
end = front;
E val = front.next.element;
front.next = front.next.next; / / Bypass first node
return(val);
}
}

Next isn't likely an operator or method. I believe its just a member variable with a reference to the next Element
SKy is right,next is not a method or operator,it is just a member variable.Can you provide the complete code so as more information can be provided on it's working...
i'll paste the code shortly, but if you say it is a variable which contain references to the next node in the list.
How does it get populated? its kind of confusing as to how the code works, I know how Linked lists work in general,
