Java 8Object Oriented ProgrammingProgramming

Search a value in a Pair Class using the contains() method.

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;

NoteSteps 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 −


import org.javatuples.Pair;
public class Demo {
   public static void main(String[] args) {
      Pair < String, String > p = Pair.with("Hardware", "Software");
      System.out.println("Pair = " + p);
      boolean res = p.contains("Firmware");
