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

    }
}

Output:

1

Example 2:




// Below is a Java program to get
// a LabelValue value
  
import java.util.*;
import org.javatuples.LabelValue;

    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();
