How to shuffle elements in Vector

import java.util.Collections;
import java.util.Vector;

public class Shuffle {

public static void main(String[] args) {

Vector<String> vector = new Vector<String>();
//add element in vector
vector.add(“cricket”);
vector.add(“hockey”);
vector.add(“football”);
vector.add(“tennish”);

// print vector
System.out.println(“Vector = “+vector);

/*
* Randomly permutes the specified list using a
*  default source of randomness.
*/
Collections.shuffle(vector);

System.out.println(“Vector after first Shuffle = “+vector);

Collections.shuffle(vector);

System.out.println(“Vector after second Shuffle = “+vector);

}
}

Output:
Vector = [cricket, hockey, football, tennish]

Vector after first Shuffle = [tennish, cricket, football, hockey]

Vector after second Shuffle = [cricket, hockey, tennish, football]
