Java 8 - Convert Array to Stream

In this article we are going to see about Java 8 - Convert Array to Stream Example

ArrayToStream.java

package com.javatutorialcorner.java8;
 
import java.util.Arrays;
import java.util.stream.IntStream;
import java.util.stream.Stream;
 
public class ArrayToStream {
 
 public static void main(String[] args) {
   String[] languages = {"Java", "C++", "Spring", "Hibernate", "R Language"};
 
         //Arrays.stream
         Stream<string> arraysStream = Arrays.stream(languages);
         arraysStream.forEach(x -> System.out.println(x));
 
         //Stream.of
         Stream<string> streamOf = Stream.of(languages);
         streamOf.forEach(x -> System.out.println(x));
          
         //For primitive array, the Arrays.stream and Stream.of will return different output.
         int[] intArray = {1, 2, 3, 4, 5};
 
         // 1. Arrays.stream -> IntStream
         IntStream intArraysStream = Arrays.stream(intArray);
         intArraysStream.forEach(x -> System.out.println(x));
 
         // 2. Stream.of-> Stream<int>
         Stream<int> intStreamOf = Stream.of(intArray);
 
         // Cant print Stream<int> directly, convert / flat it to IntStream
         IntStream intStream2 = intStreamOf.flatMapToInt(x -> Arrays.stream(x));
         intStream2.forEach(x -> System.out.println(x));
 
 }
