Int Object and Int val...

Question

Can someone tell me what the difference is between an integer object instead of an int val? I'm working with a IntList where I have to change the program so that the nodes hold an integer object rather than an int val? So if I have this example:
public void addToEnd(int val)
     IntNode newnode = new IntNode(val,null);
     //if list is empty, this will be the only node in it
     if (list == null)
         list = newnode;
     else
          //make temp point to last thing in list
          IntNode temp = list;
          while (temp.next != null)
              temp = temp.next;
          //link new node into list
          temp.next = newnode;
         count++;
    }...would I have to merely specify the following -
public void addToEnd(int object)
     IntNode newnode = new IntNode(val,object);I don't know what the object really does, so if I'm merely just switching int val to object, what's the purpose of all that?
