What Is java gui ?

GUI stands for Graphical User Interface, a term used not only in Java but in all programming languages that support the development of GUIs. A program’s graphical user interface presents an easy-to-use visual display to the user.

I think it will be very useful to learner. Any student can easily use this code and make his/her project completely.

            } else {
                String sql = "select email from admin where email=? ";
                pst = con.prepareStatement(sql);
                pst.setString(1, jTextField3.getText());
                rs = pst.executeQuery();
                if (rs.next()) {
                    JOptionPane.showMessageDialog(null, jTextField3.getText() + " Email Exist...");
                } else {
                    String sql2 = "insert into admin(name,username,password,email,cell,country) values(?,?,?,?,?,?)";
                    pst = con.prepareStatement(sql2);
                    pst.setString(1, jTextField1.getText());
                    pst.setString(2, jTextField2.getText());
