要求如下：
為《算法與數據結構設計》課程開發實驗室安排系統。該課程開課時間為2周，在兩周內需要上6次課，每次連續4個學時。
每天上午下午可各安排一次課，周末不安排上課。該系統包含兩個程序：管理員程序和教師申請程序：
在教師申請界面中：
教師錄入所授課班級ID、班級人數、不希望的時間安排（例如不安排周一上午和周四下午）；信息提交后將被存儲到后台數據庫中。
在管理員界面中：
管理員錄入現有的實驗室信息，包括實驗室地址、實驗室所能容納學生數量。管理員可以選擇“課表生成”，實驗室安排算法讀入已有
申請和實驗室信息，生成總課程安排，並寫入數據庫。
當總課程安排生成后，教師再次進入教師申請程序時，可以看到自己的課表。
請使用C/C++或Java實現。數據庫可隨意選擇。
基本要求：
(1) 兩個程序可以由同一個界面進行入口，或者分別兩個界面，不要求身份驗證；用戶只需要輸入ID即可，ID事先已寫入數據庫。
(2) 算法生成的課程安排，要求盡可能為每個老師安排6次課，所安排實驗室能容納所上課班級；按照教師申請的時間次序，盡可能
優先滿足先申請教師的期望實驗安排；當申請較多而管理員錄入的實驗室較少，允許出現有的教師申請無法滿足的情況；
(3) 實物演示時要求能夠說明所采用算法思想；
(4) 程序操作友好、健壯；操作界面簡潔美觀。
提高要求：
(1) 完善程序功能。例如身份驗證、教師與程序員可以修改自己的錄入信息等。
(2) 先進而高效的算法。
(3) 界面美觀，課表整齊美觀。
准備工作：
工具：eclipse
MySQL5.6
MySQL連接驅動：mysql-connector-java-5.1.27.jar
加載驅動：
1. 在工程目錄中創建lib文件夾，將下載好的JDBC放到該文件夾下，如下圖所示：
2. 右鍵工程名，在java build path中的Libraries分頁中選擇Add JARs...，選擇剛才添加的JDBC，如下圖：
實現步驟：
1，系統主界面的設計
用戶輸入賬號密碼后選擇教師或者管理員身份進行登錄（默認密登錄碼均為1），若果賬戶名或者密碼輸入錯誤，則無法登錄，
重新輸入，效果圖如下：

2，管理員界面設計
以管理員身份登錄成功后，可以進行信息（實驗室地址，實驗室容納量）錄入，信息修改，生成課表等操作，效果圖如下：
代碼：
package 實驗室安排系統; import java.awt.*; import java.awt.event.*; import java.sql.SQLException; import javax.swing.*; import 實驗室安排系統.MainUI; public class GlyUI extends JFrame implements ActionListener { //定義組件 JButton jb1,jb2,jb3=null; JPanel jp3,jp4=null; JLabel jlb1,jlb3,jlb4,jlb6=null; public static void main(String[] args) { GlyUI ui=new GlyUI(); } public GlyUI() { jp3=new JPanel(); jp3.setBounds(0, 220, 378, 23); getContentPane().setLayout(null); jlb1=new JLabel("\u4F60\u597D\uFF0C\u7BA1\u7406\u5458"); jlb1.setBounds(68, 15, 231, 49); getContentPane().add(jlb1); jb2=new JButton("\u4FE1\u606F\u5F55\u5165"); jb2.setBounds(15, 79, 105, 61); getContentPane().add(jb2); jb2.setForeground(Color.BLUE); jb2.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { dispose(); new GlyInputUI(); } }); //創建組件 jb3=new JButton("信息修改"); jb3.setForeground(Color.BLUE); jb3.setBounds(135, 79, 105, 61); getContentPane().add(jb3); jb3.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub dispose(); new glyxg(); } }); jb1=new JButton("\u751F\u6210\u8BFE\u8868"); jb1.setBounds(255, 79, 105, 61); getContentPane().add(jb1); jb1.setForeground(Color.BLUE); jb1.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { try { GlykbUI gl=new GlykbUI(); } catch (SQLException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } //生成課表 JOptionPane.showMessageDialog(null,"生成成功","提示消息",JOptionPane.WARNING_MESSAGE); dispose(); new GlyUI(); } }); getContentPane().add(jp3); jlb3=new JLabel("最新公告："); jlb3.setBounds(68, 180, 90, 21); getContentPane().add(jlb3); jlb3.setForeground(Color.red); jlb4=new JLabel("\u8BF7\u5C3D\u5FEB\u5B8C\u5584\u6559\u5B66\u4FE1\u606F"); jlb4.setBounds(173, 180, 162, 21); getContentPane().add(jlb4); this.setTitle("實驗室安排系統"); this.setSize(400,300); this.setLocation(500, 300); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setVisible(true); } public void actionPerformed(ActionEvent e) { } }
2.1 管理員進入信息錄入界面，輸入實驗室ID，實驗室人數后點提交，將數據長傳至數據庫，成功后點擊返回，返回到管理員界面：
其中，實驗室的數據表表結構如下：

2.2管理員修改信息設計
管理員可以修改實驗室的容量，輸入后點擊修改，將更新數據庫中的記錄信息
代碼：
package 實驗室安排系統; import java.awt.BorderLayout; import java.awt.EventQueue; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.border.EmptyBorder; import com.mysql.jdbc.Connection; import com.mysql.jdbc.PreparedStatement; import javax.swing.JLabel; import javax.swing.JOptionPane; import javax.swing.JTextField; import javax.swing.JButton; public class glyxg extends JFrame { private JPanel contentPane; private JTextField textField; private JTextField textField_1; /** * Launch the application. */ public static void main(String[] args) { new glyxg(); } /** * Create the frame. */ public glyxg() { setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setBounds(100, 100, 450, 300); contentPane = new JPanel(); contentPane.setBorder(new EmptyBorder(5, 5, 5, 5)); setContentPane(contentPane); contentPane.setLayout(null); JLabel lblNewLabel = new JLabel("\u4FEE\u6539\u5B9E\u9A8C\u5BA4\u5BB9\u91CF"); lblNewLabel.setBounds(161, 32, 252, 21); contentPane.add(lblNewLabel); JLabel lblNewLabel_1 = new JLabel("\u8BF7\u8F93\u5165\u8981\u4FEE\u6539\u7684\u5B9E\u9A8C\u5BA4ID:"); lblNewLabel_1.setBounds(40, 69, 246, 21); contentPane.add(lblNewLabel_1); textField = new JTextField(); textField.setBounds(301, 66, 96, 27); contentPane.add(textField); textField.setColumns(10); JLabel lblNewLabel_2 = new JLabel("\u8BF7\u8F93\u5165\u4FEE\u6539\u540E\u7684\u5B9E\u9A8C\u5BA4\u5BB9\u91CF\uFF1A"); lblNewLabel_2.setBounds(40, 133, 234, 21); contentPane.add(lblNewLabel_2); textField_1 = new JTextField(); textField_1.setBounds(301, 130, 96, 27); contentPane.add(textField_1); textField_1.setColumns(10); JButton btnNewButton = new JButton("\u786E\u8BA4\u4FEE\u6539"); btnNewButton.setBounds(40, 186, 163, 29); btnNewButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub String rid=textField.getText(); String ru=textField_1.getText(); int romnum=Integer.parseInt(ru); try { xg(rid, romnum); } catch (SQLException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } JOptionPane.showMessageDialog(null,"修改成功！","提示消息",JOptionPane.WARNING_MESSAGE); } });; contentPane.add(btnNewButton); JButton btnNewButton_1 = new JButton("\u8FD4\u56DE\u4E0A\u4E00\u7EA7"); btnNewButton_1.setBounds(252, 186, 145, 29); btnNewButton_1.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub dispose(); new GlyUI(); } }); contentPane.add(btnNewButton_1); this.setVisible(true); this.setLocation(500, 300); } public static void xg(String s1,int n) throws SQLException{ Connection con; String driver = "com.mysql.jdbc.Driver"; String url = "jdbc:mysql://localhost:3306/Demo"; String user = "root"; String password = "yfz"; int rs=0; try { Class.forName(driver); con = (Connection)DriverManager.getConnection(url,user,password); PreparedStatement stmt=null; String sql="update administrator set roomnum = "+String.valueOf(n)+" where roomid = "+s1; stmt=(PreparedStatement) con.prepareStatement(sql); rs = stmt.executeUpdate(); } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
2.3管理員生成課表算法
排課表算法的大致思路：
1) 同一班級的學生在同一時間不能安排在兩個實驗室
2) 同一教師在同一時間不能教授兩個班級
3) 同一實驗室在同一時間不能安排兩個班級
4) 某一實驗室上課的人數不應大於實驗室的容納量
5) 課程在一周上多次時, 要有一定的間隔性
6) 對同一教師, 同一上課對象應盡量選擇相對固定的幾個實驗室
7) 優先滿足一些特殊要求（比如有些老師喜歡上上午的課，可以優先滿足，有些老師不喜歡上某個時間片的課，我們盡量避免給他們在這個時間段排課）
因此，我將兩周的時間分為20個時間片，以老師的喜好時間為基礎來給他們安排合適的時間片來開展教學活動。時間片的排布如下：
我們這樣定義教師的數據表：
（注：id為記錄在數據表中的位置，與優先級有關，name為教師姓名，classid為教師所授班名稱，classnum為班級人數，badtime1為不想上課的時間片1，
badtime2位不想上課的時間片2，count為授課次數是6次）
定義課程表的表結構：
（注：id為記錄在數據表中的位置，與優先級有關，name為教師姓名，room為上課地點，bd1為不想上課的時間片1，bd2位不想上課的時間2,t1~t6為教師
上課的時間片）
生成課表算法：要生成A老師的課表，先通過訪問數據庫獲得A老師不想被安排上課的時間片，和A老師要上課的實驗室，在A老師的可用時間片里，為A老師
生成6個上課的時間片，並寫入到數據庫課程表表單中，供老師查詢，算法的流程圖如下;

代碼：
package 實驗室安排系統; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JOptionPane; import javax.swing.JTextField; import javax.swing.JPanel; import java.awt.GridLayout; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import com.mysql.jdbc.Connection; import com.mysql.jdbc.PreparedStatement; import com.mysql.jdbc.Statement; public class TerInputUI extends JFrame implements ActionListener { //定義組件 JPanel jp1,jp2,jp3,jp4=null; JButton jb1=null,jb2=null; JLabel jlb1,jlb2,jlb3=null; JTextField jtf1,jtf2,jtf3,jtf4=null; public static void main(String[] args) { String s=null; new TerInputUI(s); } public static void addter(String name,String classid,int classnum,int badtime1,int badtime2){ Connection con; String driver = "com.mysql.jdbc.Driver"; String url = "jdbc:mysql://localhost:3306/Demo"; String user = "root"; String password = "yfz"; try { Class.forName(driver); con=(Connection) DriverManager.getConnection(url,user,password); Statement statement = (Statement) con.createStatement(); String sql = "select count(*) from teacher"; ResultSet rs = statement.executeQuery(sql); int rowcount=0; while(rs.next()){ rowcount=rs.getInt(1); } String sql1 = "insert into teacher values(?,?,?,?,?,?,?)"; PreparedStatement pstmt; try { pstmt = (PreparedStatement) con.prepareStatement(sql1); pstmt.setInt(1, rowcount+1); pstmt.setString(2, name); pstmt.setString(3, classid); pstmt.setInt(4,classnum); pstmt.setInt(5,badtime1); pstmt.setInt(6,badtime2); pstmt.setInt(7,6); pstmt.executeUpdate(); pstmt.close(); } catch (SQLException e) { e.printStackTrace(); } rs.close(); con.close(); } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public TerInputUI(String s) { //創建組件 jb1=new JButton("提交"); jb1.setBounds(39, 0, 127, 29); jb1.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub if(jtf1.getText().isEmpty()||jtf2.getText().isEmpty()||jtf3.getText().isEmpty()||jtf4.getText().isEmpty()){ JOptionPane.showMessageDialog(null,"無效的輸入","提示消息",JOptionPane.WARNING_MESSAGE); }else{ String name=s; String clasid=jtf1.getText(); String cnum=jtf2.getText(); int clsnum=Integer.parseInt(cnum); String b1=jtf3.getText(); String b2=jtf4.getText(); int bdtime1=Integer.parseInt(b1); int bdtime2=Integer.parseInt(b2); addter(name, clasid, clsnum, bdtime1, bdtime2); JOptionPane.showMessageDialog(null,"添加成功！","提示消息",JOptionPane.WARNING_MESSAGE); } }}); jb2=new JButton("返回"); jb2.setBounds(224, 0, 127, 29); jb2.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub dispose(); new TerUI(s); } }); jp1=new JPanel(); jp2=new JPanel(); jp3=new JPanel(); jp4=new JPanel(); jlb1=new JLabel("班級ID"); jlb1.setBounds(43, 8, 90, 21); jlb2=new JLabel(" 班級人數"); jlb2.setBounds(37, 8, 95, 21); jlb3=new JLabel("\u4E0D\u60F3\u4E0A\u8BFE\u65F6\u95F4"); jlb3.setBounds(43, 8, 108, 21); jtf1=new JTextField(10); jtf1.setBounds(152, 5, 197, 27); jtf2=new JTextField(10); jtf2.setBounds(155, 5, 195, 27); jtf3=new JTextField(10); jtf3.setBounds(154, 5, 84, 27); jtf4=new JTextField(10); jtf4.setBounds(268, 5, 84, 27); jp1.setLayout(null); //加入到JPanel中 jp1.add(jlb1); jp1.add(jtf1); jp2.setLayout(null); jp2.add(jlb2); jp2.add(jtf2); jp3.setLayout(null); jp3.add(jlb3); //添加標簽 jp3.add(jtf3); jp3.add(jtf4); jp4.setLayout(null); jp4.add(jb1); //添加按鈕 jp4.add(jb2); //加入JFrame中 getContentPane().add(jp1); getContentPane().add(jp2); getContentPane().add(jp3); getContentPane().add(jp4); getContentPane().setLayout(new GridLayout(4,1)); //選擇GridLayout布局管理器 this.setTitle("實驗室安排系統"); this.setSize(400,200); this.setLocation(400, 200); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //設置當關閉窗口時，保證JVM也退出 this.setVisible(true); this.setResizable(true); } public void actionPerformed(ActionEvent e) { //事件判斷 } }
3.2教師修改信息設計
教師可以修改自己所教授的班級名稱，如圖：
代碼：
