The ArrayList<E> class

• get gets an element; no need to cast to correct type:
  String country = countries.get(i);
• set sets an element
  countries.set(1, "France");
• size method yields number of elements
  for (int i = 0; i < countries.size(); i++) . . .
• Or use "for each" loop
  

  for (String country : countries) . . .
