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

To add value in Ennead class in JavaTuples, you need to use the addAtX() method. Here, X represents the index wherein you need to add the value i.e. for index 2, use addAt2() method. Add the specific value as the parameter value of the method. For example −

addAt2(“John”);

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 add value in Ennead Tuple in Java −

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.addAt0("Newton"));
      System.out.println("Elements in the Tuple = "+e.addAt2("Stephen"));
      System.out.println("Elements in the Tuple = "+e.addAt5("Sam"));
      System.out.println("Elements in the Tuple = "+e.addAt7("Mark"));
   }
}

Output

Elements in the Tuple = [Newton, Katie, Tom, Ryan, Tom, Bradley, David, Steve, Brad, Jacob]
Elements in the Tuple = [Katie, Tom, Stephen, Ryan, Tom, Bradley, David, Steve, Brad, Jacob]
Elements in the Tuple = [Katie, Tom, Ryan, Tom, Bradley, Sam, David, Steve, Brad, Jacob]
Elements in the Tuple = [Katie, Tom, Ryan, Tom, Bradley, David, Steve, Mark, Brad, Jacob]
