I realized my Node type does not need a generic type (located in the Node class), but then I get the error above when I remove it. Is there a way to avoid this? I've also tried to define the type,...

Hey Norm, walked away for a bit.

The error after compiling.


Now, I made a quick change and I got the newMember to print..by some miracle. It is still throwing the error though. Line 128 is...

I've checked my code against several different source and I don't see any serious difference. there is nothing unique about my code and yet it still returns a nullpointer error. Can you guys please...

temp.next will have the address of the current head node...but it will contain the newest member in the list. Head should always remain the first link in the list -- that is why I used newNode =...

Ok, lets start with the addToFront method:
1. I understand the if statement...its saying if a node is empty, add the new node with its member, assign it as head, and link it with old head.
2. If...

Would you mind explaining to me exactly what is going on here. What is newNode.next = tail accomplishing? In my class NodeList, next is defined as NodeList<T>...which is the format I've adopted from...

Thank you guys. I thought so, but I just wanted to make sure -- I saw an example where they created separate classes for the two but they weren't using generics.


public class NodeList<T> {...

Is it possible create a single Node class (Node<T>) that can account for a list for integers and a list for strings? Or is it better to create a separate class to do this?

I'm not trying to compile it yet...I'm not ready for that. I have my other classes...I just provided the class with the issue. I thought the issue was contained within this class alone.

public class MySinglyLinkedListD<T> implements SinglyLinkedList<T> {

protected ListNode<T> head, tail, current;
String name;
int size = 0;

//Simple constructor

That is all the error message contained.
