In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

import java.util.*;
  public class Javacollectionexcercise {
  public static void main(String[] args) {
 
  List<String> Stringslist = new ArrayList<String>();
  Stringslist.add("Audi");
  Stringslist.add("BMW");    
  Stringslist.add("Bugatti");
  Stringslist.add("Ford");
  Stringslist.add("Honda");
  Stringslist.add("Hyundai");
 
  System.out.println("List before reversing :\n" + Stringslist);  
  Collections.reverse(Stringslist);
  System.out.println("List after reversing :\n" + Stringslist); 
 }
}

Result:

[Audi, BMW, Bugatti, Ford, Honda, Hyundai]

List after reversing :

[Hyundai, Honda, Ford, Bugatti, BMW, Audi]
