1.需求分析

功能要求：
1)需要管理的學生信息有：學號、姓名、性別、出生日期、政治面貌、家庭住址、電話、宿舍號。
2)實現查詢、增、刪、改等功能。
數據存儲：數據庫或文件。

2.本組課題及本人任務

本組的課題是學生信息管理系統，我負責的任務是完成學生信息管理系統的圖形界面。

3.總體設計（概要設計）

本組完成的是學生信息管理系統，主要的功能有增，刪，查，改，管理的學生信息有學號、姓名、性別、出生日期、政治面貌、家庭住址、電話、宿舍號。並且使用數據庫來儲存學生信息。

小組成員
翁華輝：負責完成學生信息管理系統的圖形界面，

張雨陽：負責編寫學生信息管理系統的增刪改查。

運行界面：

具體代碼：
登陸界面：
//給屏幕的寬度高度，程序窗口的寬度高度賦值
Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize();
screenSizeWidth = (int) dimension.getWidth();
screenSizeHeight = (int) dimension.getHeight();
windowWidth = this.getWidth();
windowHeight = this.getHeight();
//設置程序窗口的位置為屏幕的正中央
this.setLocation(screenSizeWidth / 2 - windowWidth / 2, screenSizeHeight / 2 - windowHeight / 2);

// 聲明姓名，密碼的標簽
JLabel username_label = new JLabel("User:");
JLabel password_label = new JLabel("Password: ");
JLabel administrator_label = new JLabel("管理員登陸");

// 聲明姓名輸入框和密碼輸入框
final JTextField user_field = new JTextField();
final JPasswordField password_field = new JPasswordField();

//聲明登錄按鈕
JButton login_btn = new JButton("登錄");
JButton exit_btn = new JButton("退出");

//設置各個標簽和輸入框的大小和位置
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

login_btn.setBounds(200, 300, 100, 50);
exit_btn.setBounds(350, 300, 100, 50);

//添加到面板
this.add(username_label);
this.add(password_label);
this.add(user_field);
