Representing Japanese letters in a Java created HTML-file

I want to write Japanese letters into a Java created HTML-file. For doing so, I created a FileOutputStream creating a .html document at a destination (like Desktop, documents). I wrote some HTML-Code into my Java Code, so it will translate it properly:

package main;

import java.io.DataOutputStream;

public class Streamer {
  static String address;
  static String output;

  public Streamer() {}

  static String html_begin = "<!DOCTYPE html><html><body>";
  static String header = "<head><meta lang=\"japanese\" charset=\"unicode\"></head>";
  static String html_end = "</html></body>";

  public static void output(String s, String s2) {
    address = s2;
    output = s;
    setAddress(s2);


    try
    {
      DataOutputStream stream = new DataOutputStream(new java.io.FileOutputStream(address));
      stream.writeBytes(html_begin);
      stream.writeBytes(header);
      stream.writeBytes(output);
      stream.writeBytes(html_end);


      stream.close();
    }
    catch (java.io.IOException localIOException) {}
  }

.....}

Even with declaring the charset as Unicode and the language as Japanese, the created file is showing me some random signs...

For information: The code directly transforms a given code at a JTextArea (String) into the HTML-embedded document. The given address as argument of FileOutputStream is just the destination the created file shall appear.

The method setAdress is just the setting method of these address.

Do not use DataOutputStream to write text files. Use a Writer to write text files. Better yet, use a PrintWriter.

To write text files with Japanese characters, you need the file to be encoded in a character set that supports Japanese characters, e.g. UTF-8 or UTF-16.

Also, you should use try-with-resources.

try (PrintWriter out = new PrintWriter(Files.newBufferedWriter(Paths.get(address), StandardCharsets.UTF_16))) {
    out.println(html_begin);
    out.println(header);
    out.println(output);
    out.println(html_end);
} catch (IOException e) {
    e.printStackTrace();
}

Pre-Java 7 you would write:

try (PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(new FileOutputStream(address), "UTF-16")))) {
    out.println(html_begin);
    out.println(header);
    out.println(output);
    out.println(html_end);
} catch (IOException e) {
    e.printStackTrace();
}
