i thought this would be a great place to get some help...

i need to create a java application that creates a linked list containing 5 String objects, i need to step through the list starting at the first printing out each string to the screen, then start at the end and print out each string to the screen until i'm back at the top of the list.

i am an extreme newbie, and am just trying to teach myself, anybody care to help?

Hi,
Here is the code that does the job for u..

import java.util.*;

class Lister
{
public static void main(String[] args)
{
/** make a new linked list */
LinkedList list = new LinkedList();

/** add five strings to the linked list */
for (int i = 0; i < 5 ; i++)
{
list.add(i,&quot;String&quot;+i);
}

/** move through the list and print out the elements from 1 to 5 */
System.out.println(&quot; From first to last &quot;
for (int i = 0 ; i < 5 ; i++)
{
System.out.println(&quot; Element No &quot;+i+&quot; &quot; + (String)list.get(i));
}

/** move through the list and print out the elements from 5 to 1 */
System.out.println(&quot;\n From last to first &quot;
for (int i = 4 ; i >= 0 ; i--)
{
System.out.println(&quot; Element No &quot;+i+&quot; &quot; + (String)list.get(i));
}
}
}

Hope this helps,
