Java: Convert Stream to List

Note: This works with Java 8 or above!

In order to convert a Stream to a List, make use of the of the toList() method form the Collectors util class when collecting the Stream.

import java.util.List;
import java.util.stream.Collectors;
import java.util.stream.Stream;

public class StreamToListExamples {

    public static void main(String[] args) {

        Stream<Integer> streamOfIntegers = Stream.of(1,2,4,5,6,7,8,9,10);
        //Stream -> List
        List<Integer> listOfIntegers = streamOfIntegers.collect(Collectors.toList());
        System.out.println(listOfIntegers);

        Stream<String> streamOfStrings = Stream.of("A","B","C","D","E");
        //Stream -> List
        List<String> listOfStrings = streamOfStrings.collect(Collectors.toList());
        System.out.println(listOfStrings);

    }
}

[1, 2, 4, 5, 6, 7, 8, 9, 10]

[A, B, C, D, E]
