Reverse order of all elements of Vector

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

public class ReverseAllelement {

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(“Before reverse Vector = “+vector);

/*
* Reverses the order of the elements in the
* specified list. This method runs in linear time.
*/
Collections.reverse(vector);

System.out.println(“After reverse Vector = “+vector);

}
}

Output:

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

After reverse Vector = [tennish, football, hockey, cricket]
