hashmap - Java - looping through LinkedhashMap and get the value -

-

i have following linkedhashmap in put values in following way:

if (preauthorizeannotation != null) {     requestmappingvalues = requestmappingannotation.value(); // url value     requestmethod[] methods = requestmappingannotation.method(); // request method type     system.out.println(+i + ":method  : " + method2.getname() + " secured   ");     //system.out.println("requestion method type : "+methods[0].name());     class[] parametertypes = method2.getparametertypes();     (class class1: parametertypes) {         userdefinedparams = new userdefinedparams();         strclassnametofix = class1.getname();         strclassname = strclassnametofix.replaceall("\\[l", "").replaceall("\\;", "");         if (class1.isarray()) {              //classobj = strclassnames.substring(strclassnames.lastindexof('.')+1, strclassnames.length()-1);             userdefinedparams.setdatatype(strclassname);             userdefinedparams.setisarray("y");             paramslist.add(userdefinedparams);         } else if (class1.isprimitive() && class1.isarray()) {             userdefinedparams.setdatatype(strclassname);             userdefinedparams.setisarray("y");             paramslist.add(userdefinedparams);         } else {             userdefinedparams.setdatatype(strclassname);             userdefinedparams.setisarray("n");             paramslist.add(userdefinedparams);         }         system.out.println("strclassname : " + strclassname);     }     paramsmap.put("url_" + i, requestmappingvalues[0]);     paramsmap.put("params_" + i, paramslist);

i try loop through map following :

for (object key: paramsmap.keyset()) {     uri = "http://localhost:8080/api" + paramsmap.get(key);     statuscode = httprequest.handlehttprequest(client, uri);     system.out.println("statuscode : " + statuscode); }

i following exception : 

java.lang.illegalargumentexception

because first time gets url correctly misses params .

i want url , paramlist separately can process it.

i trying url , corrresponding paramlist url , convert paramlist userdefined , value further process.

the best solution have 2 separate maps: 1 urls , other 1 params.

however, seems not need maps since use them lists storing urls , params. should therefore consider using 1 list urls , 1 list params, i append string being key in maps index in lists:

 urls.add(requestmappingvalues[0]);  params.add(paramslist);

and later iterate on lists retrieve values inserted.

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
