int cannot be deferenced in my code

 public boolean checkPath(LinkedList <Integer>  path,int curNode)
     {     
 LinkedList list = path;
 curNode= path.getFirst();
 boolean pathOk==true;

 while (!path.isEmpty() && pathOk)
 {
    int nextNode;
    nextNode = path.getFirst();
    if (!nextNode.isNeighbor())
     {
        pathOk = false;
        curNode = nextNode;
     }

 }
 }

i am getting int cannot be dereferenced error in my if statement......any help would be highly appreciated
