Java Program to convert Character Array to IntStream Last Updated : 11 Dec, 2018 Comments Improve Suggest changes Like Article Like Report Given a Character Array, the task is to convert this array into an IntStream containing the ASCII values of the character elements. Examples: Input: char[] = { 'G', 'e', 'e', 'k', 's' } Output: 71, 101, 101, 107, 115 Input: char[] = { 'G', 'e', 'e', 'k', 's', 'F', 'o', 'r', 'G', 'e', 'e', 'k', 's' } Output: 71, 101, 101, 107, 115, 70, 111, 114, 71, 101, 101, 107, 115 Algorithm: Get the Character Array to be converted. Convert it into Stream using Stream.of() method. Convert the formed Stream into IntStream using flatMapToInt() method. Print the formed IntStream. Below is the implementation of the above approach: Java // Java program to convert // Character Array to IntStream import java.util.stream.*; class GFG { public static void main(String[] args) { // Get the Character Array to be converted Character charArray[] = { 'G', 'e', 'e', 'k', 's' }; // Convert charArray to IntStream IntStream intStream = Stream // Convert charArray into Stream of characters .of(charArray) // Convert the Stream of characters into IntStream .flatMapToInt(IntStream::of); // Print the elements of the IntStream System.out.println("IntStream:"); intStream.forEach(System.out::println); } } Output: IntStream: 71 101 101 107 115 Comment More infoAdvertise with us Next Article Java Program to convert Character Array to IntStream R RishabhPrabhu Follow Improve Article Tags : Java Practice Tags : Java Similar Reads How to Convert Character Array to String in Java?
