java - Strange issue with populating LinkedHashSet -

-

given below code, there reason when final if-else statement steps else clause, if un-comment 2 lines of code , comment "foozanazabar" , "testcairo" lines, not add lines linkedhashset? appears add values.add(new bigdecimal(peunit).multiply(new bigdecimal(1000)).tostring()); correctly when logic drops else clause, not add bd.zero or pefamt field despite fact strings.

as note, 0 , pefamt bigdecimal's converted string. these 2 values giving me grief. direction appreciated.

public static linkedhashmap<string, linkedhashset<string>> converttransactiontabledata(resultset rs) {     linkedhashmap<string, linkedhashset<string>> returnablemap = new linkedhashmap<string, linkedhashset<string>> ();      try {         while (rs.next()){             string pefamt, pepoln, mcisst, pebrcd, peeffy, peplan;             string peunit, petrnc, peco, peityp, zero;              pepoln = rs.getstring("pepoln");             mcisst = rs.getstring("mcisst");             pebrcd = rs.getbigdecimal("pebrcd").tostring();             peeffy = rs.getbigdecimal("peeffy").tostring();             peplan = rs.getstring("peplan");             peunit = rs.getbigdecimal("peunit").tostring();             pefamt = rs.getbigdecimal("pefamt").tostring();             petrnc = rs.getstring("petrnc");             peco = rs.getstring("peco");             peityp = dataconverter.resetinsurancetype(rs.getstring("peityp"));             0 = bigdecimal.zero.toplainstring();              string policynumber = pepoln;             linkedhashset<string> values = new linkedhashset<string>();             values.add(mcisst);             values.add(pebrcd);             values.add(peeffy);             values.add(peplan);             values.add(peunit);             if (peplan.equalsignorecase("hsre")) {                 values.add(new bigdecimal(peunit).multiply(new bigdecimal(1000)).tostring());             } else {                 values.add(pefamt);             }             values.add(petrnc);             values.add(peco);             values.add(peityp);             if (dataconverter.teststringtoint(petrnc)) {                 if (integer.valueof(petrnc) >= 20 && integer.valueof(petrnc) <= 29) {                     values.add(pefamt);                     values.add(zero);                     values.add(zero);                 } else {                     values.add("foozanzabar");                     values.add("testcairo"); //                      values.add(zero); //                      values.add(pefamt);                     values.add(new bigdecimal(peunit).multiply(new bigdecimal(1000)).tostring());                 }             }             returnablemap.put(policynumber, values);         }     } catch (sqlexception sqlex) {         logger.error("problem converting resultset.  ", sqlex);     }     return returnablemap; }

thank in advance.

please note underlying data structure you're using here set means won't let add duplicates. in probability, string values of bd.zero , pefamt must present in values set , hence getting ignored.

if turns out case switch using linkedlist<string> allows have duplicates.

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
