postgresql - Correct URL for connecting to java jdbc -


i'm having trouble setting connection database here , wondering may doing wrong. error follows:

exception in thread "main" java.sql.sqlexception: no suitable driver found jdbc:postgresql://168.16.1.128:5432/dbname @ java.sql.drivermanager.getconnection(drivermanager.java:689) @ java.sql.drivermanager.getconnection(drivermanager.java:270) @ sample.dbconnect.getconnection(dbconnect.java:21) @ sample.usertest.main(usertest.java:41) connecting class looks follows:

public class dbconnect { public java.sql.connection getconnection() throws sqlexception,illegalaccessexception, classnotfoundexception {          java.sql.connection conn = null;                    string url = "jdbc:postgresql://168.16.1.128:5432/dbname";         conn = drivermanager.getconnection(url);         system.out.println("connected database");         return conn;     }    }

and heres gets called:

public class usertest {     public static void main(string[] args) throws jsonexception, sqlexception, instantiationexception, illegalaccessexception, classnotfoundexception{         dbconnect db = new dbconnect();         db.getconnection();         } }

i have feeling error may come way url written , if case can please explain me how write url? database doesnt require password , username connected to. hope can kind me.

thanks!
