Implement Triplet Class with Pair Class in Java using JavaTuples

Following are the ways to implement Triplet Class with Pair Class

1. Using direct values

   import java.util.*;
   import org.javatuples.*;
   
   class GfG {
   
       public static void main(String[] args)
       {
           // create Pair
           Pair<Integer, String>
               pair = new Pair<Integer, String>(
                   Integer.valueOf(1), "GeeksforGeeks");
   
           // Print the Pair
           System.out.println("Pair: " + pair);
   
           // Create Triplet from Pair
           Triplet<String, Integer, String>
               triplet = new Triplet<String, Integer, String>(
                   "Triplet 1", pair.getValue0(), pair.getValue1());
   
           // Print the Triplet
           System.out.println("Triplet: " + triplet);
       }
   }

   Output:

   Pair: [1, GeeksforGeeks]
   Triplet: [Triplet 1, 1, GeeksforGeeks]

2. Using Pair.add() method

   import java.util.*;
   import org.javatuples.*;
   
   class GfG {
       public static void main(String[] args)
       {
           // create Pair
           Pair<Integer, String>
               pair = new Pair<Integer, String>(
                   Integer.valueOf(1), "GeeksforGeeks");
   
           // Print the Pair
           System.out.println("Pair: " + pair);
   
           // Using add() to create Triplet
           Triplet<Integer, String, String>
               triplet = pair.add("Triplet 1");
   
           // Print the Triplet
           System.out.println("Triplet: " + triplet);
       }
   }

   Output:

   Pair: [1, GeeksforGeeks]
   Triplet: [1, GeeksforGeeks, Triplet 1]

3. Using Pair.addAtX() method

   Program 1: Adding at Position 0 using addAt0()

   import java.util.*;
   import org.javatuples.*
   
       class GfG {
       public static void main(String[] args)
       {
           // create Pair
           Pair<Integer, String>
               pair = new Pair<Integer, String>(
                   Integer.valueOf(1), "GeeksforGeeks");
   
           // Print the Pair
           System.out.println("Pair: " + pair);
   
           // Using add() to create Triplet
           Triplet<String, Integer, String>
               triplet = pair.addAt0("Triplet 1");
   
           // Print the Triplet
           System.out.println("Triplet: " + triplet);
       }
   }

   Output:

   Pair: [1, GeeksforGeeks]
   Triplet: [Triplet 1, 1, GeeksforGeeks]

   Program 2: Adding at Position 1 using addAt1()

   import java.util.*;
   import org.javatuples.*;
   
   class GfG {
       public static void main(String[] args)
       {
           // create Pair
           Pair<Integer, String>
               pair = new Pair<Integer, String>(
                   Integer.valueOf(1), "GeeksforGeeks");
   
           // Print the Pair
           System.out.println("Pair: " + pair);
   
           // Using add() to create Triplet
           Triplet<Integer, String, String>
               triplet = pair.addAt1("Triplet 1");
   
           // Print the Triplet
           System.out.println("Triplet: " + triplet);
       }
   }

   Output:

   Pair: [1, GeeksforGeeks]
   Triplet: [1, Triplet 1, GeeksforGeeks]

   Program 2: Adding at Position 2 using addAt2()

   // Below is a Java program to demonstrate
   // use of addAt2() method with
   // direct value
   
   import java.util.*;
   import org.javatuples.*
   
       class GfG {
       public static void main(String[] args)
       {
           // create Pair
           Pair<Integer, String>
               pair = new Pair<Integer, String>(
                   Integer.valueOf(1), "GeeksforGeeks");
   
           // Print the Pair
           System.out.println("Pair: " + pair);
   
           // Using add() to create Triplet
           Triplet<Integer, String, String>
               triplet = pair.addAt2("Triplet 1");
   
           // Print the Triplet
           System.out.println("Triplet: " + triplet);
       }
   }

   Output:

   Pair: [1, GeeksforGeeks]
   Triplet: [1, GeeksforGeeks, Triplet 1]
