Add a value to Triplet class in JavaTuples

The addAtX() method is used to add value to the Triplet Tuple. The index can be set here with the X i.e. the place where the value gets added.

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

import org.javatuples.Triplet;

Here, we have used Quartet class also, therefore import the following −

import org.javatuples.Quartet;

Note − Steps to download and run JavaTuples program If you are using Eclipse IDE to run Triplet 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.Triplet;
import org.javatuples.Quartet;
public class Demo {
   public static void main(String[] args) {
      Triplet < String, String, String > t1 = Triplet.with("Movies", "Web Series", "TV Shows");
      System.out.println(t1);
      Quartet < String, String, String, String > q2 = t1.addAt3("Theatre");
      System.out.println(q2);
   }
}

Output

[Movies, Web Series, TV Shows]
[Movies, Web Series, TV Shows, Theatre]
