JavaTuples addAtX() method for Quartet class

The addAtX() method is used to add a value to the Quartet 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 Quartet class in JavaTuples, you need to import the following package −

import org.javatuples.Quartet;

We will use Quintet class; therefore, we will import the following package −

import org.javatuples.Quintet;

Note − Steps to download and run JavaTuples program If you are using Eclipse IDE to run Quartet 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.Quartet;
import org.javatuples.Quintet;
public class Demo {
   public static void main(String[] args) {
      Quartet < String, String, String, String > q1 =
      Quartet.with("Football", "Hockey", "Cricket", "Tennis");
      Quintet < String, String, String, String, String > q2 =
      q1.addAt2("Squash");
      System.out.println(q2);
   }
}
