您需要将此代码放入您的Constructor.
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String input="INSERT INTO kullanicilar (TC,name,surname) VALUES(?,?,?)";
try {
PreparedStatement ps=con.prepareStatement(input);
ps.setInt(1, Integer.parseInt(textField.getText()));
ps.setString(2, textField_1.getText());
ps.setString(3, textField_2.getText());
//ps.execute();
if(ps.executeUpdate()>0) {
JOptionPane.showMessageDialog(null, "user added","user add",JOptionPane.OK_CANCEL_OPTION);
}
}catch(SQLException f) {
f.printStackTrace();
}
finally {System.out.println("pressed");}
frame.setVisible(false);
new GirisEkrani().setVisible(true);
}
});
最后,它看起来像这样,

import javax.swing.border.EmptyBorder;

//Instead of frame use this keyword

}
}
注意:-这不是与数据库通信的最佳实践。
