public class ArrayShuffle {
public static void main(String[] args) {
// Initialize the contents of our array
String[] alphabets = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J"};
// As the Collections.shuffle method need a list for the parameter we
// convert our array into List using the Arrays class.
List<String> list = Arrays.asList(alphabets);
// Here we just simply used the shuffle method of Collections class
// to shuffle out defined array.
Collections.shuffle(list);
// Run the code again and again, then you'll see how simple we do shuffling
for (String alpha : list) {
System.out.print(alpha + " ");
}
}
}
Some of the generated results are:
F E C A G B H I J D
