What is the setAtX() method of the Ennead Tuple in Java

Java 8Object Oriented ProgrammingProgramming

To set Ennead value in Java, you need to use the setAtX() method. Here, X represents the index wherein you need to set the value i.e. for index 1, use setAt1() method. Set the value as the parameter value of the method.

Let us first see what we need to work with JavaTuples. To work with Ennead class in JavaTuples, you need to import the following package −

import org.javatuples.Ennead;

Note − Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse IDE, then Right Click Project -> Properties -> Java Build Path -> Add External Jars and upload the downloaded JavaTuples jar file. Refer the below guide for all the steps to run JavaTuples −

The following is an example to set Ennead value in JavaTuples −

Example

import org.javatuples.Ennead;
public class Demo {
   public static void main(String[] args) {
      Ennead<String, String, String, String, String, String, String, String, String> e =
      Ennead.with("Katie", "Tom","Ryan", "Tom","Bradley", "David","Steve", "Brad", "Jacob");
      System.out.println("Elements in the Tuple = "+e.setAt0("Justin"));
   }
}

Output
