The following is an example to create LabelValue JavaTuples from another collection.

import java.util.*;
public class Demo {
public static void main(String[] args) {
List<Integer> myList = new ArrayList<Integer>();
myList.add(200);
myList.add(500);
LabelValue<Integer, Integer> lbValue = LabelValue.fromCollection(myList);
System.out.println("Elements in the LabelValue Tuple = "+lbValue);
}
}Output
Elements in the LabelValue Tuple = [200, 500]
