Shuffling the Elements of a List or Array</h3>
Use <code>Collections.shuffle()</code> to randomly reorder the elements in a list.
<pre>
// Create a list
List list = new ArrayList();
// Add elements to list
// Shuffle the elements in the list
Collections.shuffle(list);
// Create an array
String[] array = new String[]{"a", "b", "c"};
// Shuffle the elements in the array
Collections.shuffle(Arrays.asList(array));
</pre>
