What is LabelValue class in JavaTuples?

Java 8ProgrammingObject Oriented Programming

A LabelValue class is a Tuple of 2 elements with label as the first position, whereas value as the second. It is in the JavaTuples library. The LabelValue Tuple class is Typesafe, Immutable, Iterable, Serializable, etc.

The following is the declaration of the LabelValue class;

public final class LabelValue<P, Q>
extends Tuple
implements IValueLabel<P>, IValueValue<Q>

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

import org.javatuples.LabelValue;

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 implement the LabelValue JavaTuples class

Example

import org.javatuples.LabelValue;
public class Demo {
   public static void main(String[] args) {
      LabelValue<String, String> lbValue = LabelValue.with("Jacob", "Tom");
      System.out.println("Elements in the LabelValue Tuple = "+lbValue);
   }
}

Output

Elements in the LabelValue Tuple = [Jacob, Tom]
