Java code to generate JSON hierarchical path -

-

i working on project need parse json in java , display hierarchical path of json key/node mentioned below.

i'm developing program in java using jackson api not able readily available api return me hierarchical path of current key/node json.

json data -

{“tomcat-users”:     {         “role”:[             {“@rolename”:”manager-gui”},             {“@rolename”:”manager-script”},             {“@rolename”:”manager-jmx”},             {“@rolename”:”manager-status”}         ],         ”user”:{             “@username”:”admin”,             ”@roles”:”manager-gui,manager-script”,             ”@password”:”admin”         }     } }

output should like -

column 1                                        column 2 --------------------------------------------------------------------------- tomcat-users -> role[1] -> @rolename            manager-gui tomcat-users -> role[2] -> @rolename            manager-script tomcat-users -> role[3] -> @rolename            manager-jmx tomcat-users -> role[4] -> @rolename            manager-status tomcat-users -> user -> @username               admin tomcat-users -> user -> @roles                  manager-gui,manager-script tomcat-users -> user -> @password               admin

can please tell me, api available return me path ?

my java code -

public static void generatejsonpath(jsonnode node) {      iterator<string> fieldnames = node.getfieldnames();      while(fieldnames.hasnext()){          string fieldname = fieldnames.next();          jsonnode fieldvalue = node.get(fieldname);          if (fieldvalue.isobject()) {             system.out.println(fieldname + " -> ");             generatejsonpath(fieldvalue);          } else if(fieldvalue.isarray()) {              system.out.println(fieldname + " -> ");              iterator<?> iterator = fieldvalue.getelements();              while(iterator.hasnext()) {                  generatejsonpath((jsonnode) iterator.next());              }          } else {             string value = fieldvalue.astext();             system.out.println(fieldname + " : " + value);          }      } }

java code result -

tomcat-users ->  role ->  @rolename : manager-gui @rolename : manager-script @rolename : manager-jmx @rolename : manager-status user ->  @username : root @password : root @roles : manager-gui,manager-script,manager-jmx,manager-status

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
