Add a value to Unit Tuple in Java

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

import org.javatuples.Unit;

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

import org.javatuples.Pair;

Note − Steps to download and run JavaTuples program If you are using Eclipse IDE to run Unit Class in Java Tuples, 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.Unit;
import org.javatuples.Pair;
public class Demo {
   public static void main(String[] args) {
      Unit < String > u = Unit.with("One!");
      Pair < String, String > p = u.addAt1("Two!");
      System.out.println("Result: " + p);
   }
}

Output

Result: [One!, Two!]
