Today, a small bug of adding user input in series 2 was solved, adding user module, deleting user, and modifying user module.

The following code is a modified or added class relative to series 2

Let's first look at the modification of addpanel class: taking precautions when collecting parameters can prevent that bug.

cn. hncu. bookStore. user. ui;

Addpanel class: (add user module)

cn. hncu. bookStore. user. ui;

Deletepanel class: (delete user module)

cn. hncu. bookStore. user. ui;

UpdatePanel class: (modify user module)

cn. hncu. bookStore. user. ui;

Listpanel class (calling user function module)

The above is the whole content of this article. I hope it will be helpful to your study, and I hope you can support programming tips.
