Java Course Design (Student Information management system)

1. Demand Analysis

Functional Requirements:
1) Student information that needs to be managed is: study number, name, gender, date of birth, political appearance, home address, telephone, dorm number.
2) Implementation of query, add, delete, change and other functions.
Data storage: Database or file.

2. This group of topics and my task

The subject of this group is student information Management system, I am responsible for the task is to complete the Student Information Management system graphical interface.

3. Overall design (summary design)

This group completed the Student Information management system, the main functions of the increase, delete, check, change, the management of student information has school number, name, gender, date of birth, political appearance, home address, telephone, dormitory number. and use a database to store student information.

Group members
Weng Huahui: Responsible for the completion of the Student Information Management system graphical interface,

Zhang Yuyang: Responsible for the preparation of Student information management system additions and deletions to check.

Operating interface:

Specific code:
Login interface:
To the width height of the screen, the width of the program window is assigned a value
Dimension Dimension = Toolkit.getdefaulttoolkit (). Getscreensize ();
Screensizewidth = (int) dimension.getwidth ();
Screensizeheight = (int) dimension.getheight ();
WindowWidth = This.getwidth ();
WindowHeight = This.getheight ();
Set the location of the program window to the right center of the screen
This.setlocation (SCREENSIZEWIDTH/2-WINDOWWIDTH/2, SCREENSIZEHEIGHT/2-WINDOWHEIGHT/2);

Label of the name, password
JLabel Username_label = new JLabel ("User:");
JLabel Password_label = new JLabel ("Password:");
JLabel Administrator_label = new JLabel ("admin login");

Declare Name entry box and password entry box
Final JTextField User_field = new JTextField ();
Final JPasswordField Password_field = new JPasswordField ();

DECLARE login button
JButton login_btn = new JButton ("login");
JButton exit_btn = new JButton ("Exit");

Set the size and position of individual labels and input boxes
Username_label.setbounds (110, 100, 150, 50);
Password_label.setbounds (110, 200, 150, 50);
Administrator_label.setbounds (280, 50, 100, 50); 280, 60, 100, 30

if (User_field.gettext (). Equals (userName) && Password_ Field.gettext (). Equals (password))
{
