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.ArrayList;
import java.util.Collections;
  public class Javacollectionexcercise {
  public static void main(String[] args) {
   ArrayList<String> Stringslist1= new ArrayList<String>();
          Stringslist1.add("Audi");
          Stringslist1.add("BMW");    
          Stringslist1.add("Bugatti");
          Stringslist1.add("Ford");
          Stringslist1.add("Honda");       
 
          System.out.println("Array list before Swap:");
          for(String a: Stringslist1){
          System.out.println(a);
        }
 
         Collections.swap(Stringslist1, 0, 2);
          System.out.println("Array list after swap:");
          for(String b: Stringslist1){
          System.out.println(b);
         }
     }
}

Result:

Array list before Swap:Audi

BMW

Bugatti

Ford

Honda

Array list after swap:

Bugatti

BMW

Audi

FordHonda
