13. Shopping List

See the ArrayList presentation, pages 9-11, exercise ArrayList 4/4a/4b.

The setup code is to provide you with a sample shopping list to use in your tests.

Testing suggestion:

@Test
public void test_example() {
  ArrayList<Integer> n = new ArrayList<>();
  n.add(5); n.add(25); n.add(100);

  List<Integer> correct = Arrays.asList(5,25,100);
   
  assertEquals(correct, n);
} 

More detailed example testing code and a useless function so the tests compile.
