java - displaying Unicode text from database to JTextArea -

-

i have database has text in multiple languages english, hindi, telugu, tamil, marathi.

english , hindi text displayed perfectly. when choose other languages telugu, tamil, shows square boxes. 

            jtextarea txtmessage = new jtextarea();             txtmessage.setlinewrap( true );                  txtmessage.setwrapstyleword( true );             jscrollpane scrollpane = new jscrollpane(txtmessage);             scrollpane.setbounds(93, 125, 226, 97);             frame.getcontentpane().add(scrollpane);    lang = cblanguage.getselecteditem().tostring();  string sql2 = "select message messages language = '"+lang+"';"; try {     result = statement.executequery(sql2);     while(result.next()){         txtmessage.settext(result.getstring(1));     } } catch (sqlexception e) {             // todo auto-generated catch block         e.printstacktrace(); }

how make display tamil , telugu fonts properly?

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
