What is Octet class in JavaTuples?

Java 8Object Oriented ProgrammingProgramming

An Octetclass is a Tuple of 8 element. It is in the JavaTuples library. The following is the declaration of the Octet class:

public final class Octet<P, Q, R, S, T, U, V, W> extends Tuple implements IValue0<P>, IValue1<Q>, IValue2<Q>, IValue3<Q>, IValue4<Q>, IValue5<Q>, IValue6<Q>, IValue7<Q>

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

import org.javatuples.Octet;

Some of its features include:

  • Typesafe

  • Serializable

  • Comparable

  • Iterable

  • Immutable

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 of the Octet class in JavaTuples:

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("One", "Two","Three", "Four","Five", "Size","Seven", "Eight");
      System.out.println("Result = " + oc);
   }
}

Output

Result = [One, Two, Three, Four, Five, Size, Seven, Eight]

Above, we have added 8 elements to the Octet class in Java:

Octet < String, String, String, String, String, String, String, String > oc = Octet.with("One", "Two","Three", "Four","Five", "Size","Seven", "Eight");
