Base64 Encoder not encoding UTF-8

So I have a program that is supposed to encode UTF-8 Base64, but is not. My Encoder code is as follows:

public class Encoder {
    public static void Encode() throws IOException{
          byte[] bytes = Base64.encodeBase64(readFile("C:\\Users\\Dragon\\Desktop\\Binary\\Diamond.png", StandardCharsets.UTF_8).getBytes(StandardCharsets.UTF_8));
          String binary = new String(bytes);
          PrintWriter out = new PrintWriter("C:\\Users\\Dragon\\Desktop\\Binary\\Base64.txt");
          out.println(binary);
          out.close();
          System.out.println("Your File has been saved at C:\\Users\\Dragon\\Desktop\\Binary\\Base64.txt");
    }
    static String readFile(String path, Charset encoding) 
              throws IOException 
            {
              byte[] encoded = Files.readAllBytes(Paths.get(path));
              return new String(encoded, encoding);
            }
}

And when I decode it with this website (That has UTF-8 Functionality): http://www.base64decode.org/ I get: Input (My code made this):

However, when I encode the same exact thing using this site and not my code, It DOES have UTF-8 Formatting and decodes correctly. So what am I doing wrong?

Solution

  • You Base64.encodeBase64 take byte[] as input. You should pass result of Files.readAllBytes(Paths.get(path)) to Base64.encodeBase64 directly.
