Help with creating a doubly linked list
So I have been working with this file our teacher gave us, which is his own "list" ADT which I posted below (with out the comments so it doesn't stretch the page for ever)
My question is, I cant really creat a DLL from this because I have nothing for the head, no previous or next or any of that...So could some one help me get off to the right start? Some of my class mates were like "create a SLL and then reverse it" well thats all fine and dandy but how?
A couple other student said "With this DLL i only had to write two lines for each method to implement the list"...Can that be done? Theres NO documentation any where on a DLL for java, and the linkedList in the java api...I dont think that's a DLL...
I SERIOUSLY need a nudge in the right direction....
package assignment.four.utilities;
import java.io.Serializable;
public interface List<E> extends Serializable
public int size ();
public void clear ();
public boolean add (int index, E toAdd) throws NullPointerException,
IndexOutOfBoundsException;
public boolean add (E toAdd) throws NullPointerException;
public boolean addAll (List<? extends E> toAdd) throws NullPointerException;
public E get (int index) throws IndexOutOfBoundsException;
public E remove (int index) throws IndexOutOfBoundsException;
public E remove (E toRemove) throws NullPointerException;
public E set (int index, E toChange) throws NullPointerException,
IndexOutOfBoundsException;
public boolean isEmpty ();
public boolean contains (E toFind) throws NullPointerException;
public E [] toArray (E [] toHold) throws NullPointerException;
public E [] toArray ();
public Iterator<E> iterator ();
}Again with my statement. Using that List ADT HOW do you even get started in the right direction to creating a DLL? I can use this to create an array list but i dont think i can for a dll?

Ok thats fine and dandy but we never learned how to make a DLL we learned last semester how to make a SLL and I kinda get that but again with the So, you know how to make an SLL? Then I would suggest starting with that. For instance, you know how to define a Node or Element or whatever-you-want-to-call-it class that holds Data and Next? Start with that, and see if you can work out how to add a Previous.
"there's nothing on DLL's" except for the same line over and over "They go backwards and forwards" and Im sorry but that doesn't cut it......So, [url http://www.youtube.com/watch?v=Ijae2WHdc9I]you know how to count blocks, but you don't know how to count oranges? That is, you know how to make forward links in a list, but not backward links? Really?
Is there any examples of Java Dlls implementing lists and bla?I'm sure there are plenty, and I'm sure your google works as well as mine.
like we cant implement any thing else as far as I know, it can only be this list....When I said you need to implement the various pieces, I meant in the normal English sense of the word, not in the Java keyword sense. Implementing a Node in the general sense is part of "implements List" in the Java keyword sense.
I know the asking for a sample implementation might be considered cheating in some peoples books Yup.
but i learn best from examples, explanations and what not...There's a world of difference between an example of a different use of the concepts that you're trying to learn and just doing your work for you. Whatever concepts this lesson is teaching that are being tested and reinforced by this homework, you can find plenty of examples without somebody providing a DLL implementation for you.

Not to hard for you java types. Simply creating a doubly linked list.
How do i go about declaring a doubly linked list and add nodes to it?
see http://java.sun.com/j2se/1.3/docs/api/java/util/LinkedList.html
which is implemented as a doubly linked list:
import java.util.*;
public class ListTest {
public static void main(String [] argv) {
// synchronize if multiple threads are using list
LinkedList list = Collections.synchronizedList(
new LinkedList());
list.addFirst("this");
list.addLast("is");
list.addLast("a test");
ListIterator it = list.iterator(0);
// with iterator you can walk the list
}You can then use iterators to walk the list:

Hello people!
I have problems with sorting a doubly linked list, I have kind of got stuck just looking at the code and don't really know what I'm doing anymore...
public void sortList()
int flag = 0;
DoubleNode temp; //Doubly Linked List Node
temp = firstNode;
String tempData;
while (flag != 1)
flag = 1;
String data = (String)temp.element;
while (temp.next != null)
int comp = data.compareTo((String)temp.next.element);
if (comp > 0)
tempData = (String)temp.element;
temp.element = temp.next.element;
data = (String)temp.element;
temp.next.element = tempData;
flag = 0;
else
temp = temp.next;
data = (String)temp.element;
I'm trying to take an easy way around the problem by not swaping nodes but just the data the nodes contain. I'm pretty new to this and my prof. has just gone insane giving us this hardcore assignment.
is this code even close to be correct?
is this a good way of tackling the problem?
thanks a lot! / DanOkay, without going into any great detail about possible issues with the algorithm or code, it's gonna first be necessary to know some more about the DoubleNode class. For example, does it have a next method? If it does, then right off the bat your code will have to be adjusted so that where you have written "temp.next" you actually call the next method (which, if it is parameterless, would be "temp.next()"). As you have it written now, "temp.next" is accessing the "next" attribute of your DoubleNode instance, and I don't think that's what you're intending.

Constucting Doubly Linked Lists
Hi,
I'm trying to construct a doubly linked list with three nodes. I'm using the following code for the DLL and DLLNode classes:
public class DLL
public DLLNode first, last;
public DLL()
this.first = null;
this.last = null;
public class DLLNode
protected Object element;
protected DLLNode pred, succ;
public DLLNode (Object elem, DLLNode pred, DLLNode succ)
this.element = elem;
this.pred = pred;
this.succ = succ;
} and for the driver to create the DLL:
class CreateDLLNode
public static void main(String arg[])
DLL zoo = new DLL();
zoo.first = new DLLNode("ant", null, new DLLNode("bat", zoo.first, zoo.last));
zoo.last = new DLLNode("cat",zoo.first.succ, null);
System.out.println(zoo.first.succ.succ.element);
}However when I run the above driver I just a null pointer exception when it tried to print the third element (i.e. cat, first's successor's successor) I've figured out that this is because the link pointing from Bat to Cat isn't there, likewise the link from Bat to Ant isn't there (get another exception if I try to print zoo.last.pred.pred). I know there's something wrong with the way I've created the DLL but I don't know what.
I'd be very grateful for any help anyone can give, thanks!When you assign one variable to another (ie: thisVar=thatVar) it does not mean that thisVar will always contain whatever thatVar contains. thisVar only has what thatVar contained at the moment of the assignment.
thisVar = 1;
thatVar = 2;
thisVar = thatVar;
thatVar = 3;At the end of the above code, thisVar = 2 and thatVar = 3; thisVar does NOT equal 3.
When you set the bat's successor to zoo.last, zoo.last is null at that moment, so bat's successor will be null. That's the basic idea of where you're going wrong with that part specifically.
If you're going to go to the trouble of creating an abstract data structure, make the structure itself handle all these things. Give it an add() method with a parameter that accepts the objects. add() can then create a new node and supply the node the information about its previous/next nodes, and then the DLL can also change its own first/last if necessary.
You should not have to change any of the properties of DLL outside of the DLL. When you do, you start running into problems like the one you have here.
// assuming add at end of list
DLL's add(elem)
last.succ = new node(elem, last, null)
last = last.succ
// add in middle
DLL's add(elem, afterThisNode)
afterThisNode.succ = new node(elem, afterThisNode, afterThisNode.succ)
if(afterThisNode.succ.succ)
afterThisNode.succ.succ.pred = afterThisNodeThen you'll also need versions for where elem is going in position #1 or if it's going to be the first thing in the DLL.
Another problem with your code too though...
If you do "thisVar = new object( new object(thisVar))" then the "thisVar" being passed to the inner new object will have the original value of thisVar, not the value which references the outer new object. When your new bat is being made, the pred you're passing to it is also null. -
How do I find the smallest element of a doubly linked list?
I currently have a doubly link list, each node contains two datafields df1 and df2. I need to find the smallest of df2 contained in the list and swap it with index one - until the list is sorted.
Any ideas on how to search a doubly linked list for the smallest element would be greatly appreciated, thanks for your help.
ps: I have found methods for find an element in a list and tried to alter it to find smallest, but my dfs are objects and I am having difficulty with the comparison.
thanks so much for your time.I have given some comments in your other thread and instead of finding the minimum in each scan, you can do "neighbour-swaps". This will sort the list in fewer scans.

Why LinkedList uses doubly linked list and not single link list

Could you help me with one real world use case where we need to traverse linklist and arraylist in backward direction other than printing the linklist or arraylist in reverse order. One example is that you might want to use it as a stack. For a very large (+very+ large) stack it would out-perform the Vector-based Stack in the API.The first thing that pops into my head is an undo/redo function for a text editor. Each edit action is dumped onto such a stack. Each time you hit CTRL+Z to undo an action you go back in the stack. Each time you hit CTRL+Y to redo the action you go forward again. -
I am having a slight problem and I'm not sure what to do here. Basically, I am creating a new class (ExtendedList) that extends a Doubly Linked List class. The method below (SWAP METHOD) that I am creating is supposed to swap the content from the "this" object with the content from the "list" object that is passed in. I am also trying to do this without having to iterate through the content.
When I step through the code, it seems to swap everything fine as now the "this" object contains the content from the other list and the other list contains the content from the "this" object. My problem though is I have been given a test file to test my code... and it checks the swap function.
Well, after the swap it goes through a series of checks to make sure that the linked list was swapped correctly. Let's say I have a List1 of 4 items (A,B,C,D) and List2 of 3 items (1,2,3)... well... the swap seemingly works until I do the checks. So List1 goes through the check and it comes to 3... and it performs the following check...
if (next.prev != link) { errFlag |= NextPrevNotEquLink; break; }
And returns the error. Now... I'm not sure what I did wrong here or how to fix my code... (link by the way is my node)... but any suggestions would be GREATLY appreciated!
=========== SWAP METHOD ===========
public void swap(ExtendedList list) {
if (list == null) {
return;
ExtendedList temp = new ExtendedList();
temp.head = this.head;
temp.tail.prev = this.tail.prev;
temp.count = this.count;
this.head = list.head;
this.tail.prev = list.tail.prev;
this.tail.prev.next = list.tail;
this.count = list.count;
list.head = temp.head;

temp.tail.prev = this.tail.prev;Shouldn't this be temp.tail=this.tail?
You have assigned tail to point to the new list, but
the tail node itself still belong to the old list.When I try to do this... it gives me the error,
"The variable in an assignment to a blank must be a simple name or a simple name qualified by "this""

temp.count = this.count;
this.head = list.head;
this.tail.prev = list.tail.prev;Same case hereAnd when I do
this.tail = list.tail;
It gives me the error:

I desparately need help with these topic. Currently, I am doing a project using doubly link list data structure and swing components. However, I just could not get the data items of the doubly link list to display on the JTextArea. Is this possible at all or does anybody out there know in anyway to solve this problem?
Thanks a lot for the timely reply amolk. Here is the sample code you request for:
//The following code is my Link class:

Need help with creating a brush
Hi guys,
I wanted to ask for help with creating a brush (even a link to a tutorial will be goon enough ).
I got this sample:
I've created a brush from it, and i'm trying to get this kind of result:
but it's only duplicates it and gives me this result:
Can someone help me please understand what i need to define in order to make the brush behave like a continues brush instead of duplicate it?
Thank you very much
shlomitwhat you need to do is make a brush that looks like the tip of a brush. photoshop has several already but you can make your own that will be better.
get a paintbrush and paint a spot kind of like what you did but dont paint a stroke. make it look kindof grungy. then make your brush from that, making sure to desaturate it and everything.
EDIT:
oh, and if you bring the fill down to like 10-20% your stroke will look better -

Is there a way to create a "Horizontal Links List" from a query?
I want to display file names that I have uploaded as links to a display page.
I don't know how to create my own template yet as I've read... I saw Jes had posted this idea...
Thanks, BillYes, that is great Chris!
Thanks for the site....
Once I dynamically create the HTML for the list how do I feed it into the page?
as an item? Can I access an HTML region body dynamically?

Travwerse a linked list in a doubly linked list
I have to traverse a linked list to a doubly linked list and I am not sure how to do that.
Here is some sample code:
class linkData {
dataRecord data;
linkData next;
linkData prev;
linkData head;Should I use something like this:
if (index < (size >> 1)) {
next = header.next;
for (nextIndex=0; nextIndex<index; nextIndex++)
next = next.next;
} else {
next = header;
for (nextIndex=size; nextIndex>index; nextIndex--)
next = next.previous;
