Linked List Help
Submitted by ronenja123 on Fri, 06/05/2009 - 01:23.
I have this linked list:
public class LinkedList
{
public static ListNode start=null;
public LinkedList()
{
}
public void insert(String x)
{
ListNode current;
current=start;
ListNode node = new ListNode();
node.setData(x);
if (start==null)
{
start=node;
node.setNext(null);
}
else
{
while (current.getNext()!=null)
current=current.getNext();
node.setNext(null);
current.setNext(node);
}
//System.out.println("inserting "+node.getData());
}
public void printList()
{
ListNode current;
current=start;
while (current!=null)
{
System.out.print(current.getData()+" ");
current=current.getNext();
}
System.out.println();
}
}And I'm running a basic LinkedListTest:
LinkedList list1 = new LinkedList();
LinkedList list2 = new LinkedList();
list1.insert(23);
list2.insert(6665);
list1.printList();
list2.printList();
And for some reason, the output is:
23.0 6665.0
23.0 6665.0
If I comment out the printing of list2, the output is still 23.0 6665.0.
Somehow, the data in list2 is getting into list1.
I haven't a clue why.
Thank you so much in advance for any help.
