34. The programmer decides to use a List<Integer>, which is implemented as an ArrayList<Integer>, to store the numbers to be called by the Caller:
public class Caller {
private List<Integer> numbers;
public Caller() {
numbers = getList();
shuffleNumbers(); }
/∗ ∗ @return the numbers
private List<Integer> getList()
{ /∗ implementation not shown ∗/ }
/∗ ∗ Shuffle the numbers. ∗ / private void shuffleNumbers()
{ /∗ implementation not shown ∗/ }
∗ /
