Implement Quartet Class with Triplet Class in Java using JavaTuples

Last Updated : 11 Jul, 2025

Following are the ways to implement Quartet Class with Triplet Class

Using direct values

Java

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

class GfG {
    public static void main(String[] args)
    {

        // create Triplet
        Triplet<String, String, String>
            triplet = new Triplet<String, String, String>(
                "Triplet 1", "1", "GeeksforGeeks");

        // Print Triplet
        System.out.println("Triplet: " + triplet);

        // Create Quartet from Triplet
        Quartet<String, String, String, String>
            quartet = new Quartet<String, String, String, String>(
                "Quartet 1",
                triplet.getValue0(),
                triplet.getValue1(),
                triplet.getValue2());

        // Print Quartet
        System.out.println("Quartet: " + quartet);
    }
}

Output:

[Triplet 1, 1, GeeksforGeeks]
[Quartet 1, Triplet 1, 1, GeeksforGeeks]

Using Triplet.add() method

Java

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

class GfG {
    public static void main(String[] args)
    {
        // create Triplet
        Triplet<String, String, String>
            triplet = new Triplet<String, String, String>(
                "Triplet 1", "1", "GeeksforGeeks");

        // Print Triplet
        System.out.println("Triplet: " + triplet);

        // Using add() to create Quartet
        Quartet<String, String, String, String>
            quartet = triplet.add("Quartet 1");

        // Print Quartet
        System.out.println("Quartet: " + quartet);
    }
}

Output:

Triplet: [Triplet 1, 1, GeeksforGeeks]
Quartet: [Triplet 1, 1, GeeksforGeeks, Quartet 1]

Using Triplet.addAtX() method Program 1: Adding at Position 0 using addAt0()

Java

// Below is a Java program to demonstrate
// use of addAt0() method with
// direct value

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

    class GfG {
    public static void main(String[] args)
    {
        /// create Triplet
        Triplet<String, String, String>
            triplet = new Triplet<String, String, String>(
                "Triplet 1", "1", "GeeksforGeeks");

        // Print Triplet
        System.out.println("Triplet: " + triplet);

        // Using add() to create Quartet
        Quartet<String, String, String, String>
            quartet = triplet.addAt0("Quartet 1");

        // Print Quartet
        System.out.println("Quartet: " + quartet);
    }
}

Output:

Triplet: [Triplet 1, 1, GeeksforGeeks]
Quartet: [Quartet 1, Triplet 1, 1, GeeksforGeeks]

Program 2: Adding at Position 1 using addAt1()

Java

// Below is a Java program to demonstrate
// use of addAt1() method with
// direct value

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

class GfG {
    public static void main(String[] args)
    {
        // create Triplet
        Triplet<String, String, String>
            triplet = new Triplet<String, String, String>(
                "Triplet 1", "1", "GeeksforGeeks");

        // Print Triplet
        System.out.println("Triplet: " + triplet);

        // Using add() to create Quartet
        Quartet<String, String, String, String>
            quartet = triplet.addAt1("Quartet 1");

        // Print Quartet
        System.out.println("Quartet: " + quartet);
    }
}

Output:

Triplet: [Triplet 1, 1, GeeksforGeeks]
Quartet: [Triplet 1, Quartet 1, 1, GeeksforGeeks]

Program 3: Adding at Position 2 using addAt2()

Java

// 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 Triplet
        Triplet<String, String, String>
            triplet = new Triplet<String, String, String>(
                "Triplet 1", "1", "GeeksforGeeks");

        // Print Triplet
        System.out.println("Triplet: " + triplet);

        // Using add() to create Quartet
        Quartet<String, String, String, String>
            quartet = triplet.addAt2("Quartet 1");

        // Print Quartet
        System.out.println("Quartet: " + quartet);
    }
}

Output:

Triplet: [Triplet 1, 1, GeeksforGeeks]
Quartet: [Triplet 1, 1, Quartet 1, GeeksforGeeks]

Program 4: Adding at Position 3 using addAt3()

Java

// 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 Triplet
        Triplet<String, String, String>
            triplet = new Triplet<String, String, String>(
                "Triplet 1", "1", "GeeksforGeeks");

        // Print Triplet
        System.out.println("Triplet: " + triplet);

        // Using add() to create Quartet
        Quartet<String, String, String, String>
            quartet = triplet.addAt3("Quartet 1");

        // Print Quartet
        System.out.println("Quartet: " + quartet);
    }
}

Output:

Triplet: [Triplet 1, 1, GeeksforGeeks]
Quartet: [Triplet 1, 1, GeeksforGeeks, Quartet 1]
