Implement Decade Class from Ennead Class in Java using JavaTuples

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

1. Using direct values Output:

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

2. Using Ennead.add() method Output:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

   Program 9: Adding at Position 8 using addAt8() Output:

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

   Program 10: Adding at Position 9 using addAt9()

Output:

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