java - JDBC MySQL connection without specifying password -

is possible connect mysql database without specifying username , password in java code :

connection con=drivermanager.getconnection("database url","username","password");

or there way alter username , password using java?

i don't know if can setup default user, can set user no password.

as sec question, assuming connection has adequet rights in mysql, can set password on user. basic way do:

update user set password=password('new_pass') user = 'someuser';

optionally may want specify host field in clause. needs ran in msql database.
