Currently, I am detecting text/html or text/plain mime types by doing hack, which notices results that begin with and end with and make them html results. But now I also want to detect latex mime type and this hack is npt working anymore, but I cannot figure out the better way to create mime types. Here is my current code:

    private void method(String code) {
    HashMap<String, String> map3 = new HashMap<>();
    if(code != null){
          boolean resultHtml = code.startsWith("<html>") && code.endsWith("</html>");
          map3.put(resultHtml ? "text/html" : "text/plain", code);
        }
    }

if you are reading the content from a file then consider http://stackoverflow.com/questions/51438/getting-a-files-mime-type-in-java – Scary Wombat Feb 28 '17 at 00:40
Use apache Tika https://tika.apache.org/1.14/detection.html – Yohannes Gebremariam Feb 28 '17 at 00:42
@ScaryWombat no I am not reading a file, I am receiving code as a string. – fishera Feb 28 '17 at 01:49
@YohannesGebremariam I have tried Tika. It can detect Html, but it is reading others as text/plain `String contentType = new Tika().detect(code.getBytes());` – fishera Feb 28 '17 at 01:50
You should also consider the case of `code` – Scary Wombat Feb 28 '17 at 01:50
@ScaryWombat where can I find that case? – fishera Feb 28 '17 at 01:56
@YohannesGebremariam and also Tika has a lot of dependencies, almost 20 jars – fishera Feb 28 '17 at 01:58
For LaTeX files you could try using Tika to find plaintext files (LaTeX files are plain text files containing markup commands) and then search for identifying LaTeX commands. `\begin{document}` would be a good choice. – jwaddell Feb 28 '17 at 03:45
