It seems that my remove() method didn't correct the previous references. I kinda need this class again for another assignment, which is going to be a total nightmare. Also my code for...

Ok, I think I fixed the get() method so it works.

However, what's wrong with the remove method? Wait, maybe nothing is after all, but what about the alternateString()?

public void remove(int index)
{
if ((index<0) || (index>=size))
{
JOptionPane.showMessageDialog(null, "You cannot remove an out-of-bounds value!", "Invalid removal",...

What if the list is of size 1 or greater before you add anything?

Adding it to size 1 should make head = newNode and tail = oldHead;

adding to size 2 or greater should make new node head and...

Now my addFirst() is busted!
~X(~X(~X(:-s:-s^:)^^:)^b-(b-(:-o:-<[-O<:((>:D<#-o

What's wrong now?

public void addFirst(T data)
{
// Node<T> newnode = new Node<T>(data,head,...

package Assignment4;

import javax.swing.JOptionPane;
import java.util.*;
import java.io.*;



public class DoublyLinkedList<T>
{

Thanks. However, what will it do with the value that was originally the tail? Does it automatically set the previous value to be be the old tail.

like this:

oldtail = newnode.previous;
...

Ok, but what does:


public void addLast(T data)
{
Node<T> current;


current = tail;
if (tail == null)

^:)^^:)^^:)^:-t:-t:-t:-t

I thought head was the first Node in the list and tail was the last Node in the list. Was I wrong?

In a list of size 5, head would certainly not be null. Unless I'm...

is my addLast() method doing this:

1.) creating a Node current and setting it to tail

2.) setting the tail to the value after current;

3.) setting the old tail to the new tail.previous

if...

No, it's not a circular list.

package Assignment4;

import javax.swing.JOptionPane;
import java.util.*;
import java.io.*;

public class DoublyLinkedList<T>
{

Yes, but for one, how do you modify the constructor to get it to work now with tail? tail could be null, or it could be head if size =1, or it could be anything else.

My constructor is what's...

First off, how to fix the Node constructor now for each time I make a new Node.

This code was changed from a SinglyLinkedList code:

public class SinglyLinkedList<T>
{
private class Node<T>...

I need to create a DoublyLinkedList class


import javax.swing.JOptionPane;
import java.util.*;
import java.io.*;

public class DoublyLinkedList<T>
{
private class Node<T>
