Method swap to the Pair class of that swaps the first and second elements value of the pair in generic Pair class in java

public class PairDemo
{
   public static void main(String[] args)
   {
      String[] names = { "Tom", "Diana", "Harry" };
      Pair<String, Integer> result = firstContaining(names, "a");
      System.out.println(result.getFirst());
      System.out.println("Expected: Diana");
      System.out.println(result.getSecond());
      System.out.println("Expected: 1");
      swap();
   }


   public static Pair<String, Integer> firstContaining(
      String[] strings, String sub)
   {
      for (int i = 0; i < strings.length; i++)
      {
         if (strings[i].contains(sub))
         {
            return new Pair<String, Integer>(strings[i], i);
         }
      }
      return new Pair<String, Integer>(null, -1);
