Detailed Description

Key concepts from this tutorial exercise:

1. import java.util.*; to use ArrayList.
2. ArrayList<Integer> deck = new ArrayList<>(); to create an ArrayList of Integer.
3. an_array[index] => an_arrayList.get(index)
4. an_array[index] = value => an_arrayList.set(index, value)
5. an_array.length => an_arrayList.size()
6. How to program swap() for ArrayList: for (int i = 0; i < an_arrayList.size(); i++) { int index = (int) (Math.random() * an_arrayList.size()); int temp = an_arrayList.get(i); an_arrayList.set(i, an_arrayList.get(index)); an_arrayList.set(index, temp); }
