Here's my code:
DataOutputStream dos;
File _file= new File("description.rtf");
byte[] bytes1 = ("\\'20").getBytes();

try {
dos = new DataOutputStream(new FileOutputStream(_file));
dos.write(bytes1);
dos.writeBytes("https://www.disney.com");
dos.write(bytes1);
// dos.writeBytes("{\\field{\\*\\fldinst HYPERLINK \"https://www.disney.com/\"}{\\fldrslt Disney}}");
dos.close();
} catch (IOException io) {
io.printStackTrace();
}

The following does not create a hyperlink, nor do any iterations of the above. What am I missing?
