Shuffling the Elements of a List or Array

Shuffling the Elements of a List or Array

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[]{"M", "e", "g", "h", "a"};

// Shuffle the elements in the array

Collections.shuffle(Arrays.asList(array));
