           Class.forName("com.mysql.jdbc.Driver").newInstance();
           Connection con = DriverManager.getConnection("jdbc:mysql://localhost/finalprojects", "root", "password");
           Statement st = con.createStatement();
           ResultSet rs = st.executeQuery("select * from users where user ='" + user + "' and password ='" + password +"';");
           connected = true;
           rs.close();
           st.close();
           return connected;
        }catch(Exception e){
