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), "Lazyroar");            // 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, Lazyroar]
   Triplet: [Triplet 1, 1, Lazyroar]

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), "Lazyroar");            // 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, Lazyroar]
   Triplet: [1, Lazyroar, 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), "Lazyroar");            // 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, Lazyroar]
   Triplet: [Triplet 1, 1, Lazyroar]

   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), "Lazyroar");            // 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, Lazyroar]
   Triplet: [1, Triplet 1, Lazyroar]

   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), "Lazyroar");            // 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, Lazyroar]
   Triplet: [1, Lazyroar, Triplet 1]
