Fetch the value in a Java Pair Class Tuple

Use the getValueX() method to fetch the value from Pair Tuple class in Java at a particular index. For example, getValue0().

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;

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;
public class Demo {
   public static void main(String[] args) {
      Pair < String, String > p1 = Pair.with("One", "Two");
      Pair < String, String > p2 = p1.setAt1("Three");
      System.out.println("Result = " + p2);
      System.out.println("Fetch Value: " + p2.getValue0());
   }
}

Output

Result = [One, Three]
Fetch Value: One
