Prerequisite: Septet Class, Sextet Class

Below are the methods to implement a Septet Class using Sextet Class in Java:

1. Using direct values
   
   

   
   
   

   // Java program to illustrate // implementing Septet Class  // from Sextet Class  // using direct values    import java.util.*; import org.javatuples.*;    class GfG {        public static void main(String[] args)     {         // Create Sextet         Sextet<String, String, String, String, String, String>             sextet = new Sextet<String, String, String, String, String, String>(                 "Sextet", "Quintet", "Quartet", "Triplet", "Pair", "Unit");            // Print the Sextet         System.out.println("Sextet: " + sextet);            // Create Septet from Sextet         Septet<String, String, String, String, String, String, String>             septet = new Septet<String, String, String, String, String, String, String>(                 "Septet",                 sextet.getValue0(),                 sextet.getValue1(),                 sextet.getValue2(),                 sextet.getValue3(),                 sextet.getValue4(),                 sextet.getValue5());            // Print the Septet         System.out.println("Septet: " + septet);     } }

   Output:

   Sextet: [Sextet, Quintet, Quartet, Triplet, Pair, Unit]
   Septet: [Septet, Sextet, Quintet, Quartet, Triplet, Pair, Unit]
   

2. Using Sextet.add() method
   // Java program to illustrate
   // implementing Septet Class
   // from Sextet Class
   // using add()
   
   

   
   
   

   import java.util.*; import org.javatuples.*;    class GfG {     public static void main(String[] args)     {         // Create Sextet         Sextet<String, String, String, String, String, String>             sextet = new Sextet<String, String, String, String, String, String>(                 "Sextet", "Quintet", "Quartet", "Triplet", "Pair", "Unit");            // Print the Sextet         System.out.println("Sextet: " + sextet);            // Create Septet from Sextet         Septet<String, String, String, String, String, String, String>             septet = sextet.add("Septet");            // Print the Septet         System.out.println("Septet: " + septet);     } }

   Output:

   
   
   
   

   Sextet: [Sextet, Quintet, Quartet, Triplet, Pair, Unit]
   Septet: [Sextet, Quintet, Quartet, Triplet, Pair, Unit, Septet]
   

3. Using Sextet.addAtX() method

   Program 1: Adding at Position 0 using addAt0()

   
   

   
   
   

   // Java program to illustrate // implementing Septet Class  // from Sextet Class  // using addAt0()    import java.util.*; import org.javatuples.*        class GfG {     public static void main(String[] args)     {         // Create Sextet         Sextet<String, String, String, String, String, String>             sextet = new Sextet<String, String, String, String, String, String>(                 "Sextet", "Quintet", "Quartet", "Triplet", "Pair", "Unit");            // Print the Sextet         System.out.println("Sextet: " + sextet);            // Create Septet from Sextet         Septet<String, String, String, String, String, String, String>             septet = sextet.addAt0("Septet");            // Print the Septet         System.out.println("Septet: " + septet);     } }

   Output:

   Sextet: [Sextet, Quintet, Quartet, Triplet, Pair, Unit]
   Septet: [Septet, Sextet, Quintet, Quartet, Triplet, Pair, Unit]
   

   Program 2: Adding at Position 1 using addAt1()

   
   

   
   
   

   // Java program to illustrate // implementing Septet Class  // from Sextet Class  // using addAt1()    import java.util.*; import org.javatuples.*;    class GfG {     public static void main(String[] args)     {         // Create Sextet         Sextet<String, String, String, String, String, String>             sextet = new Sextet<String, String, String, String, String, String>(                 "Sextet", "Quintet", "Quartet", "Triplet", "Pair", "Unit");            // Print the Sextet         System.out.println("Sextet: " + sextet);            // Create Septet from Sextet         Septet<String, String, String, String, String, String, String>             septet = sextet.addAt1("Septet");            // Print the Septet         System.out.println("Septet: " + septet);     } }

   Output:

   Sextet: [Sextet, Quintet, Quartet, Triplet, Pair, Unit]
   Septet: [Sextet, Septet, Quintet, Quartet, Triplet, Pair, Unit]
   

   Program 3: 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 Sextet         Sextet<String, String, String, String, String, String>             sextet = new Sextet<String, String, String, String, String, String>(                 "Sextet", "Quintet", "Quartet", "Triplet", "Pair", "Unit");            // Print the Sextet         System.out.println("Sextet: " + sextet);            // Create Septet from Sextet         Septet<String, String, String, String, String, String, String>             septet = sextet.addAt2("Septet");            // Print the Septet         System.out.println("Septet: " + septet);     } }

   Output:

   Sextet: [Sextet, Quintet, Quartet, Triplet, Pair, Unit]
   Septet: [Sextet, Quintet, Septet, Quartet, Triplet, Pair, Unit]
   

   Program 4: Adding at Position 3 using addAt3()
