The following is an example to set Octet value in Java −

Example

import org.javatuples.Octet;
public class Demo {
   public static void main(String[] args) {
      Octet<String, String, String, String, String, String, String, String> oc = Octet.with(
         "laptop", "desktop","mobile", "tablet","monitor", "LCD","LED", "OLED");
      // index 0
      System.out.println(oc.setAt0("SSD"));
      // index 1
      System.out.println(oc.setAt1("HDD"));
      // index 4
      System.out.println(oc.setAt4("Pen Drive"));
      // index 5
      System.out.println(oc.setAt5("Headphone"));
   }
}

Output

[SSD, desktop, mobile, tablet, monitor, LCD, LED, OLED]
[laptop, HDD, mobile, tablet, monitor, LCD, LED, OLED]
[laptop, desktop, mobile, tablet, Pen Drive, LCD, LED, OLED]
[laptop, desktop, mobile, tablet, monitor, Headphone, LED, OLED]
