Add a value to Pair Tuple in Java
The addAtX() method is used to add a value at a particular position represented by X here. For example, addAt0() at 0 index, addAt1() at 1st index, etc.
Let us first see what we need to work with JavaTuples. To work with Pair class in JavaTuples, you need to import the following package −
import org.javatuples.Pair;
Here we have also used the Triplet class, therefore import the following package −
import org.javatuples.Triplet;
Note − Steps to download and run JavaTuples program If you are using Eclipse IDE to run Pair 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.Pair;
import org.javatuples.Triplet;
public class Demo {
public static void main(String[] args) {
Pair < String, String > p = Pair.with("Mobile", "Desktop");
System.out.println("Initial = " + p);
Triplet < String, String, String > res = p.addAt0("Tablet");
System.out.println("Result = " + res);
}
}Output
Initial = [Mobile, Desktop] Result = [Tablet, Mobile, Desktop]
