Setatx Method of the Decade Tuple in Java

The setAtX() method is used to set a new value in the Decade Tuple. Here, X is the index wherein you want to set the value. For example, setAt5() sets the value at index 5. The value to be included is to be set as the value in the parameter, like

setAt5(“Katie”);

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

import org.javatuples.Decade;

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

Steps: How to run JavaTuples program in Eclipse

The following is an example to set Decade value in Java

Example

import org.javatuples.Decade;
public class Demo {
   public static void main(String[] args) {
      // Tuple with 10 elements
      Decade<String, String, String, String, String, String, String, String, String, String> d =
         Decade.with("AB","CD", "EF","GH", "IJ","KL", "MN","OP", "QR", "ST");
      System.out.println("Elements in the Decade Tuple = ");
      Decade<String, String, String, String, String, String, String, String, String, String> d2 = d.setAt6("UV");
      System.out.println("Updated Tuple = "+d2);
   }
}

Output

Elements in the Decade Tuple =
Updated Tuple = [AB, CD, EF, GH, IJ, KL, UV, OP, QR, ST]
