java - Server using a table that I didn't even mention in my code -

-

im using netbeans 8.0 . i've created table "full" in database "face" . earlier , created table "student" in database "rishi" . , after deleting table database "rishi" & after changing database "full" , following error :-

java.sql.sqlexception: base table or view not found message server: "table 'face.student' doesn't exist".

here's html code :-

<html> <head>     <title>todo supply title</title>     <meta charset="utf-8">     <meta name="viewport" content="width=device-width, initial-scale=1.0"> </head> <body>     <center>         <h1>login !</h1>         <hr>         <form action = "check" method = "post">             <pre>                 enter email :     <input type = "text" name = "email">                 enter password :  <input type = "password" name = "pass">                 <input type = "submit" value = "login">             </pre>         </form>         <hr>         <h3>new ? sign in today !</h3>         <form action = "new" method = "post">             <pre>                 enter name :        <input type = "text" name = "user">                 enter email :       <input type = "text" name = "newemail">                 enter password :    <input type="password" name = "newpass">                 re-enter password : <input type="password" name = "repass">                                     <input type = "submit" value = "sign up">             </pre>         </form>     </center> </body> </html>

and here's servlet :-

public class new extends httpservlet {      @override     protected void doget(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {         printwriter out = response.getwriter();         string name = request.getparameter("user");         string email = request.getparameter("newemail");         string pass = request.getparameter("newpass");         string repass = request.getparameter("repass");          try {             class.forname("com.mysql.jdbc.driver");             connection con = drivermanager.getconnection("jdbc:mysql://localhost:3306/face" , "root" , "root");             statement st = con.createstatement();             resultset r = st.executequery("select * full");             int flag = 0;          while(r.next()) {             string s = r.getstring(2);             if(pass.equals(repass) || email.equals(s)) {                 flag = 1;             }             else {                 flag = 2;             }              if(flag == 2) {                 response.sendredirect("fail2.html");             }             else {                 string qr = string.format("insert student values('%s','%s','%s')" , name , email , pass);                 st.executeupdate(qr);                 response.sendredirect("home.html");             }         }          catch (classnotfoundexception ex) {             out.println("cannot load driver !");         } catch (sqlexception ex) {             out.println(ex);         }            }      @override     protected void dopost(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {        doget(request,response);     }  }

what possibly going wrong ?

thank in advance !

sorry bad - re-read question.. in fact database connection fine, because still have database face

the problem insert statement - trying insert data table non existent in database. 

string qr = string.format("insert student values('%s','%s','%s')" , name , email , pass);

this problem lies - either have make table student in "new" database, or change existing in db.

string qr = string.format("insert " insert valid table name here "values('%s','%s','%s')" , name , email , pass);

but want address different issue - not understand why have ? 

if(pass.equals(repass) || email.equals(s)) {     flag = 1; } else {     flag = 2; } if(flag == 2) {     response.sendredirect("fail2.html"); } else {     string qr = string.format("insert student values('%s','%s','%s')" , name , email , pass);     st.executeupdate(qr);     response.sendredirect("home.html"); }

this block seems (to me) redundat because check if credentials mach if set flag 1 - far good, if don't set flag 2. thats fine - why have if statement check if flag 2 ? , if redirect fail.html. otherwise query... kind of redundand ( unless expect more 2 flags) if dont block below lot nicer solution

if(pass.equals(repass) || email.equals(s)) {     string qr = string.format("insert student values('%s','%s','%s')" , name , email , pass);     st.executeupdate(qr);     response.sendredirect("home.html"); } else {     response.sendredirect("fail2.html"); }
