Implement Triplet Class with Pair Class in Java using JavaTuples

Following are the ways to implement Triplet Class with Pair Class

Using direct values

import java.util.*;
import org.javatuples.*;

class Prutor {

public static void main(String[] args)
{
// create Pair
Pair<Integer, String>
pair = new Pair<Integer, String>(
Integer.valueOf(1), "PrutordotAi");

// 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, PrutordotAi]
Triplet: [Triplet 1, 1, PrutordotAi]
Using Pair.add() method

import java.util.*;
import org.javatuples.*;

class Prutor {
public static void main(String[] args)
{
// create Pair
Pair<Integer, String>
pair = new Pair<Integer, String>(
Integer.valueOf(1), "PrutordotAi");

// 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, PrutordotAi]
Triplet: [1, PrutordotAi, Triplet 1]
Using Pair.addAtX() method
Program 1: Adding at Position 0 using addAt0()

import java.util.*;
import org.javatuples.*

class Prutor {
public static void main(String[] args)
{
// create Pair
Pair<Integer, String>
pair = new Pair<Integer, String>(
Integer.valueOf(1), "PrutordotAi");

// 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, PrutordotAi]
Triplet: [Triplet 1, 1, PrutordotAi]
Program 2: Adding at Position 1 using addAt1()

import java.util.*;
import org.javatuples.*;

class Prutor {
public static void main(String[] args)
{
// create Pair
Pair<Integer, String>
pair = new Pair<Integer, String>(
Integer.valueOf(1), "PrutordotAi");

// 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, PrutordotAi]
Triplet: [1, Triplet 1, PrutordotAi]
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 Prutor {
public static void main(String[] args)
{
// create Pair
Pair<Integer, String>
pair = new Pair<Integer, String>(
Integer.valueOf(1), "PrutordotAi");

// 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, PrutordotAi]
Triplet: [1, PrutordotAi, Triplet 1]
