Question

我有我的Base64解码器：

public class Decoder {
    public static void Decode() throws IOException{
        String s = "";
        String output = "";
         Scanner sc = new Scanner(new File("C:\\Users\\Dragon\\Desktop\\Binary\\Base64.txt"));

            while (sc.hasNextLine()) {
                s += sc.nextLine();
                System.out.println(s);
            }
            sc.close();
        byte[] bytes = Base64.decodeBase64(Files.readAllBytes(Paths.get("C:\\Users\\Dragon\\Desktop\\Binary\\Base64.txt")));
        Writer out = new BufferedWriter(new OutputStreamWriter(
                new FileOutputStream("C:\\Users\\Dragon\\Desktop\\Binary\\Base64.png"), "UTF8"));
        for(int i =0; i < bytes.length; i++){
            output+=bytes[i];
            out.write(bytes[i]);
            System.out.println((char)bytes[i]);
        }
      out.close();
      System.out.println("Your File has been saved at C:\\Users\\Dragon\\Desktop\\Binary\\Base64.png");
    }
}

当我输入

我知道我的编码器工作正常，因为当我把我的

进入本网站： http://www.base64decode.org/我得到了预期的输出。我的解码器出了什么问题？

Base64解码器不输出UTF-8
