By:Roy.LiuLast updated:2019-08-17
A Java 8 example to show you how to convert a Stream to a List via Collectors.toList
Java8Example1.java
package com.mkyong.java8; import java.util.List; import java.util.stream.Collectors; import java.util.stream.Stream; public class Java8Example1 { public static void main(String[] args) { Stream<String> language = Stream.of("java", "python", "node"); //Convert a Stream to List List<String> result = language.collect(Collectors.toList()); result.forEach(System.out::println);
output
java python node
Yet another example, filter a number 3 and convert it to a List.
Java8Example2.java
package com.mkyong.java8; import java.util.List; import java.util.stream.Collectors; import java.util.stream.Stream; public class Java8Example2 { public static void main(String[] args) { Stream<Integer> number = Stream.of(1, 2, 3, 4, 5); List<Integer> result2 = number.filter(x -> x != 3).collect(Collectors.toList()); result2.forEach(x -> System.out.println(x));
output
