mysql - how the command 'use database-name' is using java code -

-

i make o program store data excel files in databases. have plenty of databases in program have choose in 1 store data. have made code able connect mysql program , show available databases. in database store data. more specific user first of see tha available databases in client , afterwards have chance in database data stored. me how this?

the code see available databases below:

class.forname("com.mysql.jdbc.driver");         connection con = (connection) drivermanager.getconnection(                 "jdbc:mysql://localhost:3306/", "root", "root");         databasemetadata meta = (databasemetadata) con.getmetadata();         resultset res = meta.getcatalogs();         system.out.println("list of databases: ");         while (res.next()){             system.out.println (" " +res.getstring(1));     }

thank in advance!

i hope this link should . can data connection object

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...
