Java 8 Creating a Stream from an Array

Write a Java program that creates a Stream from the given array.
In Java 8, you can either use Arrays.stream or Stream.of to convert an Array into a Stream.

Java 8 - Creating a Stream from an Array

package net.sourcecodeexamples.java; import java.util.Arrays; import java.util.stream.IntStream; import java.util.stream.Stream; public class Main { public static void main(String[] args) { // String array String[] arr = { "One", "Two", "Three", "Four", "Five" }; // array to Stream Stream < String > stream1 = Arrays.stream(arr); Stream < String > stream2 = Arrays.stream(arr, 0, 2); Stream < String > stream3 = Arrays.asList(arr).stream(); Stream < String > stream4 = Arrays.asList(arr).subList(0, 2).stream(); Stream < String > stream5 = Stream.of(arr); Stream < String > stream6 = Stream.of("One", "Two", "Three"); stream1.forEach(System.out::println); stream2.forEach(System.out::println); stream3.forEach(System.out::println); stream4.forEach(System.out::println); stream5.forEach(System.out::println); stream6.forEach(System.out::println); // integers array int[] integers = { 2, 3, 4, 1 }; Integer[] boxedInt = { 2, 3, 4, 1 }; IntStream intStream1 = Arrays.stream(integers); IntStream intStream2 = IntStream.of(integers); IntStream intStream3 = IntStream.range(0, integers.length);; IntStream intStream4 = IntStream.rangeClosed(0, integers.length); Stream < Integer > intStream5 = Stream.of(boxedInt); int[] intArray1 = intStream1.toArray(); int[] intArray2 = intStream5.mapToInt(i - > i).toArray(); } }

Output

One Two Three Four Five One Two One Two Three Four Five One Two One Two Three Four Five One Two Three
