fix the encoding in the servlets(java)

Question

Help fix the encoding in the servlet, it does not display Russian characters in the output.I will be very grateful for answers.

That is servlet code

import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class servlet extends HttpServlet {
    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    public static List<String> getFileNames(File directory, String extension) {

        List<String> list = new ArrayList<String>();
        File[] total = directory.listFiles();
        for (File file : total) {
            if (file.getName().endsWith(extension)) {
                list.add(file.getName());
            }
            if (file.isDirectory()) {
                List<String> tempList = getFileNames(file, extension);
                list.addAll(tempList);          
            }
        }
        return list;
    }



@SuppressWarnings("resource")
        protected void doPost(HttpServletRequest request, HttpServletResponse response) 
                throws ServletException, IOException{ 
                request.setCharacterEncoding("utf8");
                response.setContentType("text/html; charset=UTF-8");
                String myName = request.getParameter("text");

                List<String> files = getFileNames(new File("C:\\Users\\vany\\Desktop\\test"), "txt");
                for (String string : files) {
                if (myName.equals(string)) {
                       try {
                            File file = new File("C:\\Users\\vany\\Desktop\\test\\" + string);
                            FileReader reader = new FileReader(file);
                            int b;
                            PrintWriter writer = response.getWriter();
                            writer.print("<html>");
                            writer.print("<head>");
                            writer.print("<title>HelloWorld</title>");
                            writer.print("<body>");
                            writer.write("<div>");
                            while((b = reader.read()) != -1) {
                                writer.write((char) b);
                            }
                            writer.write("</div>");
                            writer.print("</body>");
                            writer.print("</html>");

                        } 
                       catch (Exception ex) {

                        }
                    }

                }
               }
        }

Here is what I have displayed instead of letters

п»ї СЂС€РЅС€РЅС‰ РѕР»СЂСЂС€С€С€ РѕС€РіРЅС€С‰ С€РіС€Рі РѕСЂРѕСЂРіСЂРіСЂ РС‚Рѕ С…СЂРµРЅСЊ СЂР°Р±РѕС‚Р°РµС‚ СѓСЂР°

unless the list of files are not changed in dir, keep global list `List` and load it thru `init()` method. — vels4j, Nov 07 '12 at 18:06
If you know that you can send me the code please how to fix encoding simply I'm still new, and where it then paste in the code — Eric Scot, Nov 07 '12 at 18:18

You're setting the character encoding on the request instead of the response. Change request.setCharacterEncoding("utf8"); to response.setCharacterEncoding("UTF-8");

Also: if the default character encoding of your system isn't UTF-8, you should explicitly set the encoding when reading from the file. To do that, you'd need to use an FileInputStream

Can you help make it, I'm just a novice in java – Eric Scot Nov 07 '12 at 17:28
would be very much appreciated – Eric Scot Nov 07 '12 at 17:28
If someone can help not difficult to do so, which is above described @Chris – Eric Scot Nov 07 '12 at 17:34
@EricScot: that's not how it works. You don't simply repeat how much you want it. You try to do it on your own *and* show us what you tried and what you've read. Simply nagging others to do your work like this is not productive. – Joachim Sauer Nov 16 '12 at 14:13
@Chris At response.setCharacterEncoding("UFT-8"); u have spell error it is "UTF-8" – Borislav Nikolaev Apr 26 '20 at 22:54
