JavaTuples setLabel() method

The setLabel() method in org.javatuples is used to set the label of the LabelValue Class object. This method can be used with only LabelValue class object of javatuples library. It returns another LabelValueClassObject with the Label as the element passed as the parameter, and the value from the previous LabelValueClassObject.

Method Declaration:

public <X> LabelValue<X, B> setLabel(X label)

Syntax:

LabelValue<X, B> LabelValueClassObject = LabelValue.setLabel(X label)

Return Value: This method returns another LabelValueClassObject with the Label as the element passed as the parameter, and the value from the previous LabelValueClassObject.

Below are programs that will illustrate the various ways to use setLabel() method:

Example 1:

// Below is a Java program to set
// label in a LabelValue pair

import java.util.*;
import org.javatuples.LabelValue;

class GfG {
    public static void main(String[] args)
    {
        // Creating a LabelValue object
        LabelValue<Integer, String> lv
            = LabelValue.with(Integer.valueOf(1),
                              "A computer science portal");

        // Using setLabel() method
        LabelValue<String, String> lv1 = lv.setLabel("GeeksforGeeks");

        // Printing the returned LabelValue
        System.out.println(lv1);
    }
}

Output:

[GeeksforGeeks, A computer science portal]

Example 2:

// Below is a Java program to set
// label in a LabelValue pair

import java.util.*;
import org.javatuples.LabelValue;

class GfG {
    public static void main(String[] args)
    {
        // Creating a LabelValue object
        LabelValue<Integer, String> lv
            = LabelValue.with(Integer.valueOf(1),
                              "1");

        // Using setLabel() method
        LabelValue<String, String> lv1 = lv.setLabel("One");

        // Printing the returned LabelValue
        System.out.println(lv1);
    }
}

Output:

[One, 1]
