Use Collections.shuffle() to randomly reorder the elements in a list. 
    // 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));
