java - Insert and update methods of dao are not working -

-

for reason adduser(), updateuser() methods not working. can 1 please @ code , figure out i'm making mistake.

    public void adduser(user user) {         try {             preparedstatement preparedstatement = connection.preparestatement("insert users(userid, firstname, lastname, jobtitle, email, username, password) values (?,?,?,?,?,?,?)");             // parameters start 1             preparedstatement.setint(1,user.getuserid());               preparedstatement.setstring(2, user.getfirstname());             preparedstatement.setstring(3, user.getlastname());                        preparedstatement.setstring(4, user.getjobtitle());             preparedstatement.setstring(5, user.getemail());             preparedstatement.setstring(6, user.getusername());                              preparedstatement.setstring(7, user.getpassword());              preparedstatement.executeupdate();          } catch (sqlexception e) {             e.printstacktrace();         }     }      public void updateuser(user user) {         try {             preparedstatement preparedstatement = connection.preparestatement("update users  set email=?,  password=? username=?");              preparedstatement.setstring(1, user.getemail());               preparedstatement.setstring(2, user.getusername());             preparedstatement.setstring(3, user.getpassword());               preparedstatement.executeupdate();          } catch (sqlexception e) {             e.printstacktrace();         }     }

please note don't have experience in java. there no error being printed, why can't tell wrong.

thank in advance.

in updateuser(), order of parameters wrong. sql statement, should email, password , username.

preparedstatement.setstring(1, user.getemail());   preparedstatement.setstring(2, user.getpassword());     preparedstatement.setstring(3, user.getusername());

also, suggest add "finally" block close statement , result set.
