Create Septet Tuple from another collection in Java

The fromCollection() method is used in JavaTuples to create Septet Tuple from another collection. We will see an example of creating a Septet Tuple using List collection.

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

import org.javatuples.Septet;

Note − Steps to download and run JavaTuples program. If you are using Eclipse IDE to run Septet Class in JavaTuples, then Right Click Project ->Properties ->Java Build Path ->Add External Jars and upload the downloaded JavaTuples jar file.

The following is an example −

Example

import org.javatuples.Septet;
import java.util.*;
public class Demo {
   public static void main(String[] args) {
      List < String > myList = new ArrayList < String > ();
      myList.add("Keyboard");
      myList.add("Mouse");
      myList.add("Mic");
      myList.add("Battery");
      myList.add("Mousepad");
      myList.add("Charger");
      myList.add("HardDisk");
      Septet < String, String, String, String, String, String, String > s =
      Septet.fromCollection(myList);
      System.out.println(s);
   }
}

Output

[Keyboard, Mouse, Mic, Battery, Mousepad, Charger, HardDisk]
