How to swap elements of vector

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

public class SwapElement {

    public static void main(String[] args) {
        Vector<String> vector = new Vector<String>();
        //add element in vector
        // print vector
        System.out.println("Before swap Vector = "+vector);
         * Swaps the elements at the specified positions
         * in the specified list. (If the specified
         * positions are equal, invoking this method
         * leaves the list unchanged.)
        Collections.swap(vector, 1, 3);
        System.out.println("After swap vector = "+vector);


Before swap Vector = [cricket, hockey, football, tennish]

After swap vector = [cricket, tennish, football, hockey]
