Create Ennead Tuple from a List Collection in Java

To create Ennead Tuple from a List collection, use the fromCollection() method. Firstly, create a List like this and then create an Ennead Tuple using List

List<String> myList = new ArrayList<String>();
myList.add("Accessories");
myList.add("Shirt");
myList.add("Trousers");
myList.add("Furniture");
myList.add("Smart Wearable Tech");
myList.add("Smart Home Automation");
myList.add("Books");
myList.add("Stationery");
myList.add("Instrument");

Let us first see what we need to work with JavaTuples. To work with Ennead class in JavaTuples, you need to import the following package

import org.javatuples.Ennead;

Note Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse IDE, then Right Click Project -> Properties -> Java Build Path -> Add External Jars and upload the downloaded JavaTuples jar file. Refer the below guide for all the steps to run JavaTuples

The following is an example to create Ennead Tuple from another collection in Java

Example

import org.javatuples.Ennead;
import java.util.*;
public class Demo {
   public static void main(String[] args) {
      List<String> myList = new ArrayList<String>();
      myList.add("Accessories");
      myList.add("Shirt");
      myList.add("Trousers");
      myList.add("Furniture");
      myList.add("Smart Wearable Tech");
      myList.add("Smart Home Automation");
      myList.add("Books");
      myList.add("Stationery");
      myList.add("Instrument");
      Ennead<String, String, String, String, String, String, String, String, String> e =
         Ennead.fromCollection(myList);
      System.out.println("Elements in the Ennead Tuple = ");
      for (Object ele : e)
         System.out.println(ele);
   }
}

Output

Elements in the Ennead Tuple =
Accessories
Shirt
Trousers
Furniture
Smart Wearable Tech
Smart Home Automation
Books
Stationery
Instrument
