I. Introduction (P)
1. Introduce the business problem
Teachers in Kim Lien school are having difficulty in managing their students, and they want an app that will allow them to
manage students more readily and conveniently rather than on paper.
Problem: When a school manages student information in the usual manner, it will spend a lot of time looking for student
information, and it will also spend a lot of time searching for documents connected to student information. And the issue
here is that, instead of using paper, Kim Lien school requires an application that can display and save student information.
Solution: I will make an app to help Kim Lien school organize its students more efficiently, saving time, searching for student
information and not storing it.

On the interface of the program, there will be a section to fill in student information, a list of students, and search for student
by Name, Address, Date of Birth, Telephone.

When click in button “Add new*”, all components will be reset, the text “Adding new student…” also button “Cancel” will
appear, “Add new*” become “Submit”. Besides, user can enter all information except Student ID. ID will increase one after
an add action.

Figure 7. Telephone & Name functions controlling data type
Two functions allow Telephone in number and Name in letter, delete or space.
For example, I enter “V” in telephone field and app show me the message.
Figure 8. Messages if invalid input
This function below allow me to display image in “jbAvatar” by get link from my computer (selectedImagePath).
Figure 10. Add successfully
When the admin uses the search function, the admin will enter the Name, Address, Date of Birth or Telephone. Then the
code in private void txtSearchKeyReleased will be run. Before that, you must create TableRowSorter.
Figure 11. TableRowSorter Figure 12. Search function
An implementation of RowSorter that provides sorting and filtering using a TableModel.
Figure 14. Delete function
Select the row of student which user want to delete.
Figure 15. Choose one row
When users want to use the edit function, they must select the row of items displayed on the table to get the data of that
row. The student's information will be displayed and allow you to correct the information.
In the example below, I changed the name "Nguyen Thi B" to "Nguyen Dieu Binh" and modified the information under the
table view.
