Implement Ennead Class from Octet Class in Java using JavaTuples
Implementing the Ennead class from the Octet class in Java using JavaTuples is a crucial aspect of data structure manipulation in Java programming. The Ennead class, which represents a 9-tuple, can be derived from the Octet class, which represents an 8-tuple. The implementation allows for the creation of a new 9-tuple by adding an additional element to the existing 8-tuple.
What is Ennead Class in JavaTuple?
The Ennead class is a tuple from the JavaTuples library that deals with 9 elements. It is a generic class capable of holding any type of value within it. The Ennead class inherits various characteristics from JavaTuples, such as being typesafe, immutable, iterable, serializable, and comparable.
What is Octet Class in JavaTuple?
The Octet class in JavaTuples is a tuple that consists of eight elements. It is a part of the JavaTuples library and is a generic class capable of holding any type of value within it. The Octet class inherits various characteristics from JavaTuples, such as being typesafe, immutable, iterable, serializable, and comparable.
Approach 1: Using Direct Values
To implement the Ennead class from the Octet class in Java using JavaTuples with direct values, you can create instances of the Octet and Ennead classes directly with specific values.
- Create an Octet instance with the desired values.
- Create an Ennead instance using the values from the Octet instance, and add an additional value.
- Access the individual values from the Ennead instance and store them in separate variables.
- Output the values from the Ennead instance to the console.

import java.util.*; // Custom Octet class representing an 8-tuple class Octet{ public T1 value1; public T2 value2; public T3 value3; public T4 value4; public T5 value5; public T6 value6; public T7 value7; public T8 value8; // Constructor to initialize the Octet with the given values public Octet(T1 value1, T2 value2, T3 value3, T4 value4, T5 value5, T6 value6, T7 value7, T8 value8) { this.value1 = value1; this.value2 = value2; this.value3 = value3; this.value4 = value4; this.value5 = value5; this.value6 = value6; this.value7 = value7; this.value8 = value8; } } // Custom Ennead class representing a 9-tuple class Ennead { public T1 value1; public T2 value2; public T3 value3; public T4 value4; public T5 value5; public T6 value6; public T7 value7; public T8 value8; public T9 value9; // Constructor to initialize the Ennead with the given values public Ennead(T1 value1, T2 value2, T3 value3, T4 value4, T5 value5, T6 value6, T7 value7, T8 value8, T9 value9) { this.value1 = value1; this.value2 = value2; this.value3 = value3; this.value4 = value4; this.value5 = value5; this.value6 = value6; this.value7 = value7; this.value8 = value8; this.value9 = value9; } } public class EnneadOctetExample1 { public static void main(String[] args) { // Creating an Octet with direct values Octet octet = new Octet<>("Java", 8, 3.14, true, 'A', 100L, 2.5f, (short) 10); // Creating an Ennead from the Octet with an additional value Ennead ennead = new Ennead<>(octet.value1, octet.value2, octet.value3, octet.value4, octet.value5, octet.value6, octet.value7, octet.value8, "Extra"); // Accessing values from the Ennead String value1 = ennead.value1; Integer value2 = ennead.value2; Double value3 = ennead.value3; Boolean value4 = ennead.value4; Character value5 = ennead.value5; Long value6 = ennead.value6; Float value7 = ennead.value7; Short value8 = ennead.value8; String value9 = ennead.value9; // Outputting the values System.out.println("Values in Ennead:"); System.out.println(value1); System.out.println(value2); System.out.println(value3); System.out.println(value4); System.out.println(value5); System.out.println(value6); System.out.println(value7); System.out.println(value8); System.out.println(value9); } }
Output:
Values in Ennead: Java 8 3.14 true A 100 2.5 10 Extra
Approach 2: Using Octet.add()
- Define a custom class called Octet that holds 8 different types of values.
- Create an Octet object with values like a string, integer, double, boolean, character, long, float, and short.
- Define a method in the Octet class to add another value and create an Ennead (a 9-tuple).
- Create an Ennead object by adding an extra value to the Octet object.
- Access the values stored in the Ennead object.
- Print out the values of the Ennead object to the console.

Output:
Values in Ennead: Java 8 3.14 true A 100 2.5 10 Extra
Approach 3: Using Octet.addAtX() method (Where X = 0,1,2,3,4,5,6,7,8)
In this approach, we enhance the Octet class by introducing the addAtX() method, where X represents the position (0 to 8) at which a new value can be added.
