Iterable Generics don't compile with foreach iterations

Question

I cannot get this code to work with any variation (including casts):
  public class PointList<Waypoint> extends Object implements Iterable {
    private List<Waypoint> theList = new ArrayList();
    public Iterator<Waypoint> iterator() {
      return theList.iterator();
    /* Other methods to implement specific functionality ... */
  private PointList<Waypoint> waypoints = new PointList();
  /** Creates a new instance of GenericsTestClass */
  public GenericsTestClass() {
  public void printWaypoints() {
    for (Waypoint waypoint: waypoints) {       // ***** This line does not compile *****
      System.out.println(waypoint.toString());
    for (Iterator<Waypoint> it = waypoints.iterator(); it.hasNext(); ) {
      Waypoint waypoint = it.next();
      System.out.println(waypoint.toString());
  }Everything compiles except for the flagged line which has the following error:
found   : java.lang.Object
required: naverus.navdata.Waypoint
    for (Waypoint waypoint: waypoints) { Note the second "old style" iteration which works fine.
Any explanation or suggestions would be much appreciated.
Thanks

Pls See the response and let me know if it works
I cannot get this code to work with any variation
(including casts):
public class PointList<Waypoint> extends Object> implements Iterable {
// What is Waypoint?
// USE generics in new ArrayList()
private List<Waypoint> theList = new ArrayList();
public Iterator<Waypoint> iterator() {
return theList.iterator();
/* Other methods to implement specific
functionality ... */
// USE generics in new PointList()
private PointList<Waypoint> waypoints = new
PointList();

public GenericsTestClass() {
public void printWaypoints() {

This line does not compile *****
System.out.println(waypoint.toString());
