Implementing Iterable interface

Question

Just trying to implement the the Iterable<> interface into my Stack class ... as far as I can tell I cannot specify a type beyond Object when iterating through it using the ForEach loop structure. Any thoughts on how to correct this or is my design limited?

import java.util.*;
public class Stack<T> implements Iterable<T>
     private LinkedList<T> list;
     private int size;
    public Stack()
         list = new LinkedList<T>();
         size = 0;
    public void push(T node)
         if (node != null)
              list.addFirst(node);
              size++;
         else
              System.out.println("Cannot push null value onto stack.");
    public T pop()
         T removedNode = null;
         if (!isEmpty())
              removedNode = list.removeFirst();
         else
              System.out.println("Stack is empty.");
         return(removedNode);
    public T[] toArray()
         return((T[]) list.toArray());
    public boolean isEmpty()
         return(size == 0);
    public boolean equals(LinkedList vList)
         return(list.equals(vList));
    public Iterator<T> iterator()
         return(list.iterator());
    public static void main(String[] args)
         Stack s1 = new Stack<Integer>();
         for (int count=0; count< 10; count++)
              s1.push(new Integer(count)); //(int)(Math.random()*16+0)
         for(Object i : s1) //RIGHT HERE, I want to be able to say "Integer i : s1" but I get an incompatible types error
              System.out.println(i);
}I don't really understand why I would be getting the error stating the the type being sent back is Object ... my Iterator() method returns an iterator of type T not type Object from how I understood it... any thoughts?

Answer 1

// Stack  s1 = new Stack<Integer>(); // this loses the type information
Stack <Integer> s1 = new Stack<Integer>();
