help me on this: circular doubly linked list

[someone]

You have to write a program to support the following operations regarding a circular doubly linked list with sentinels



a. Create empty list
b. Insert a key into the list
c. Search a key in the list
d. Delete a key form the list (Hint: search first and delete if found)
e. Display all the keys in the list
f. Destroy the list (Hint: use multiple deletes)

What do you want help on? No one is going to write it for you. So ask a question and recieve an answer or type of some code and post a problem you discovered with code.

Other than that, we can't help you.

[someone]

yes I know I want to know where should I start. I mean I got trouble with start creating the list. if any one have idea just tell me

Thanks Dark

Normally I start off my programs with this:

public class myProgram
{
    public static void main(Strings[] args)
    {
    }
}

That's what I do. Any other questions?

[someone]

my question was regard the linked list it self
how can I start creating an empty list.

[dswastik]

Using java apis or using your own class?

can you explain what data structure inside the linked list is planned?

how to create empty list with linked list !

[dswastik]

Have you gone through the api docs?

List<String> al=new LinkedList<String>();

[Dark]

*Sigh* j2me64 just asked you what type of information are you trying to store in this list?

Strings? Integers? Doubles? Booleans?

[j2me64]

how to create empty list with linked list !

yes, but in order to create an empty linked list you must first specify which attributes and methods the class should have and then inside the constructor you can initialize your linked list.

@OP: please don't double post.

not exactly. it would be great if the planned linked list could store any type of objects. with my question i want to know what kind of nodes and other data structures the list should contain.

[Dark]

True but I still don't think he understands that. I was trying to give him examples to base what he wanted in there. I doubt with his knowledge the program will be calling for a very extensive list.
