Create Octet Tuple from another collection in Java

Java 8Object Oriented ProgrammingProgramming

You can create Octel Tuple from another collection i.e. List or arrays. For List, use the fromCollection() method.

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

import org.javatuples.Octet;

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 Octet Tuple from another collection in Java −

Example

import org.javatuples.Octet;
import java.util.*;

public class Demo {
   public static void main(String[] args) {
      List<Integer> myList = new ArrayList<Integer>();
      myList.add(25);
      myList.add(50);
      myList.add(75);
      myList.add(100);
      myList.add(125);
      myList.add(150);
      myList.add(175);
      myList.add(200);
      Octet<Integer, Integer, Integer, Integer, Integer, Integer, Integer, Integer> oc = Octet.fromCollection(myList);
      System.out.println("Result = " + oc);
   }
}

Output

Result = [25, 50, 75, 100, 125, 150, 175, 200]
Above, we have created a List and add some elements using the add() method. You need to add 8 elements for Octet:
List<Integer> myList = new ArrayList<Integer>();
myList.add(25);
myList.add(50);
myList.add(75);
myList.add(100);
myList.add(125);
myList.add(150);
myList.add(175);
myList.add(200);

Now, use the fromCollection() method to set the List to Octet a create a new Octet with the elements of the List −

Octet<Integer, Integer, Integer, Integer, Integer, Integer, Integer, Integer> oc = Octet.fromCollection(myList);
