Here's the method up to now
public DNode removeDnode(DNode v, DNode e, DNode f)
{
e = v.nextNode();
f = v.prevNode();
f.setNext() = e;
e.setPrev() = f;
v.setPrev(null);
v.setNext(null);
size = size - 1;
return v;
}
Here's my node class
public class DNode
{
public String element;
public DNode next;
public DNode previous;
public DNode(String e, DNode n)
{
element = e;
next = n;
}
public void setElement(String newElem)
{
element = newElem;
}
public void setNext(DNode newNext)
{
next = newNext;
}
public void setPrev(DNode newPrev)
{
previous = newPrev;
}
public String getElement()
{
return element;
}
public DNode nextNode()
{
return next;
}
public DNode prevNode()
{
return previous;
}
}
I'm getting the error 'method setNext in class DNode cannot be applied to given types but I don't know why. Any help?
(Don't read this this is to use characters so it will let me post)
EDIT: new method below
public DNode removeDnode(DNode current)
{
DNode next = current.nextNode();
DNode previous = current.prevNode();
previous.setNext(next);
next.setPrev(previous);
current.setPrev(null);
current.setNext(null);
size = size - 1;
return current;
}
but how do I deal with the end and beginning of the list
You need to do:
f.setNext(e);
e.setPrev(f);
