package com.sample.app;

import java.nio.charset.StandardCharsets;

public class App {
 
 private static void printByteArray(byte[] arr) {
  for(byte b: arr) {
   System.out.print(b + " ");
  }
  System.out.println();
 }

 public static void main(String args[]){
  String str = "Hello World";
  
  byte[] bytes = str.getBytes(StandardCharsets.UTF_8);
  
  printByteArray(bytes);
 }

}
