Create LabelValue Tuple from a List collection in Java

To create LabelValue tuple from a List collection, use the fromCollection() method. Here, we will be creating LabelValue from List, therefore use the fromCollection() method.

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 −

The following is an example to create LabelValue JavaTuples from a List collection −

Example

import org.javatuples.LabelValue;
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]
Above, we have created a List with 2 elements:
List<Integer> myList = new ArrayList<Integer>();
myList.add(200);
myList.add(500);

Now, use the fromCollection() method to create a LabelValue tuple from a List collection in Java −

LabelValue<Integer, Integer> lbValue = LabelValue.fromCollection(myList);
