Java Tuples addAtX() method for Pair class

Java 8Object Oriented ProgrammingProgramming

The addAtX() method is used to add value at a particular position represented by X here.

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.addAt1("Tablet");
      System.out.println("Result = " + res);
   }
}

Output

Initial = [Mobile, Desktop]
Result = [Mobile, Tablet, Desktop]
