Implement Ennead Class from Octet Class in Java using JavaTuples

Prerequisite: Ennead Class, Octet Class Below are the methods to implement a Ennead Class using Octet Class in Java:

1. Using direct values Output:

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

2. Using Octet.add() method Output:

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

3. Using Octet.addAtX() method Program 1: Adding at Position 0 using addAt0() Output:

   Octet: [Octet, Sextet, Quintet, Quartet, Triplet, Pair, Unit]
   Ennead: [Ennead, Octet, Sextet, Quintet, Quartet, Triplet, Pair, Unit]
   

   Program 2: Adding at Position 1 using addAt1() Output:

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

   Program 3: Adding at Position 2 using addAt2() Output:

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

   Program 4: Adding at Position 3 using addAt3() Output:

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

   Program 5: Adding at Position 4 using addAt4() Output:

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

   Program 6: Adding at Position 5 using addAt5() Output:

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

   Program 7: Adding at Position 6 using addAt6() Output:

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

   Program 8: Adding at Position 7 using addAt7() Output:

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

   Program 9: Adding at Position 8 using addAt8()

Output:

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