JavaTuples getLabel() method

The getLabel() method in org.javatuples is used to fetch the label from the TupleClassObject from the LabelValue Class. This method can be used with only LabelValue class object of javatuples library. It returns a Label which is the element present at the index 0 of the LabelValueClassObject. The returned Label is ensures the type-safety.

Method Declaration:

public A getLabel()

Syntax:

LabelValue LabelValueClassObject = LabelValue.with(A a, B b);
A val = LabelValueClassObject.getLabel()

Return Value: This method returns a Label which is the element present at the index 0 of the LabelValueClassObject.

Below programs illustrate the various ways to use getLabel() method:

Example 1:

// Below is a Java program to get
// a LabelValue value

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), "GeeksforGeeks");

        // Using getLabel() method
        int label = lv.getLabel();

        // Printing the Label
        System.out.println(label);
    }
}

Output:

1

Example 2:

// Below is a Java program to get
// a LabelValue value

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

class GfG {
    public static void main(String[] args)
    {
        // Creating a LabelValue object
        LabelValue<String, String> lv
            = LabelValue.with("GeeksforGeeks",
                              "A Computer Science Portal for Geeks");

        // Using getLabel() method
        String label = lv.getLabel();

        // Printing the Label
        System.out.println(label);
    }
}

Output:

GeeksforGeeks
