根据题目要求，本次采用JAVA添加GUI界面，并根据上次老师点评的要求下对原数独实现进行一定改进，因此，JAVA源码如下：
1、GUI界面设计如下
1 package JAVA练习; 2 import javax.swing.*; 3 import java.awt.*; 4 import java.awt.event.*; 5 import java.util.Random; 6 7 public class ShuDu extends JFrame{ 8 private static final long serialVersionUID = 5952689219411916553L; //序列化字段 9 private static JTextField a[][] = new JTextField[9][9]; //存储文本框中的数字 10 static int ans[][] = new int[9][9]; //存储输入后的两位数组 11 SudoGenerator example = new SudoGenerator(); 12 public int right[][] = example.generatePuzzleMatrix(); 13 public int rightans[][]; 14 private int[][] Wk(int a[][]){ //挖空 15 Random r = new Random(); 16 int a1, a2; 17 a1 = r.nextInt(9); 18 a2 = r.nextInt(9); 19 for(int i = 0; i < 100; i++) 20 { 21 a[a1][a2] = 0; 22 a1 = r.nextInt(9); 23 a2 = r.nextInt(9); 24 } 25 return a; 26 } 27 public ShuDu(){ 28 Container c = getContentPane(); 29 c.setLayout(new BorderLayout(2, 1)); //边框布局 30 JMenuItem jmiOk = new JMenuItem("提交"); //定义菜单 31 JMenuItem jmiExplain = new JMenuItem("详情"); 32 JMenuItem jmiMessage = new JMenuItem("信息"); 33 34 JPanel panel = new JPanel(); //定义一个容器 35 panel.add(jmiOk); //将菜单在容器内显示 36 panel.add(jmiExplain); 37 panel.add(jmiMessage); 38 JPanel p1 = new JPanel(new GridLayout(9, 9, 5, 5)); //定义9行9列的网格布局 39 add(panel,BorderLayout.NORTH); //将菜单放置在北面 40 add(p1,BorderLayout.CENTER); //将数字放置在正中间 41 rightans = Wk(right); 42 for(int k = 0;k<9; k ++) 43 { 44 for(int n=0;n<9;n++) 45 { 46 if(rightans[k][n] != 0) 47 { 48 a[k][n] = new JTextField("" + rightans[k][n]); 49 a[k][n].setHorizontalAlignment(JTextField.CENTER);//将数字水平居中 50 a[k][n].setEditable(false); //只可显示不可修改 51 p1.add(a[k][n]); //添加文本框 52 } 53 else 54 { 55 a[k][n] = new JTextField(); 56 a[k][n].setHorizontalAlignment(JTextField.CENTER); 57 p1.add(a[k][n]); 58 } 59 } 60 } 61 add(p1); //将数字面板显示在容器里 62 jmiOk.addActionListener(new ActionListener(){//匿名创建事件监听器 63 public void actionPerformed(ActionEvent e) 64 { 65 if(gettext() == 1) 66 { 67 if(judge() == true) 68 { 69 JOptionPane.showMessageDialog(null, "Your answer is right!","Result",JOptionPane.INFORMATION_MESSAGE); 70 } 71 else 72 { 73 JOptionPane.showMessageDialog(null, "Your answer is wrong!","Result",JOptionPane.INFORMATION_MESSAGE); 74 } 75 } 76 } 77 }); 78 explainListenerClass listener2 = new explainListenerClass(); 79 jmiExplain.addActionListener(listener2); 80 messageListenerClass listener3 = new messageListenerClass(); 81 jmiMessage.addActionListener(listener3); 82 } 83 84 static int gettext() //获取文本框的文字 85 { 86 int i,j; 87 for(i = 0; i < 9; i++) 88 { 89 for(j = 0; j < 9 ; j ++) 90 { 91 ans[i][j] = 0; 92 } 93 } 94 for(int k = 0;k < 9; k++) 95 { 96 for(int n = 0;n < 9; n++) 97 { 98 try //异常处理 99 { 100 ans[k][n] = Integer.parseInt(a[k][n].getText()); //将答案类型转换之后传给ans 101 } 102 catch(NumberFormatException nfe) 103 { 104 JOptionPane.showMessageDialog(null,"数据中包括非数字，请重新输入"); 105 return 0; 106 } 107 } 108 } 109 return 1; 110 } 111 public static boolean judge() //判断输入的答案是否正确 112 { 113 int i,j,k; 114 int [][]answer = ans; 115 116 for(i = 0; i < 9; i ++) 117 { 118 if(judge9(answer[i]) == false) //判断每列是否有重复数字 119 return false; 120 } 121 for(j = 0; j < 9; j ++) //判断每行是否有重复数字 122 { 123 124 int[] newAnswerColumn = new int[9]; 125 for(i = 0; i < 9; i ++) 126 { 127 newAnswerColumn[i] = answer[i][j]; 128 } 129 if(judge9(newAnswerColumn) == false) 130 return false; 131 } 132 for(i = 0; i < 3; i ++) //判断每个小九宫格内是否有重复数字 133 { 134 for(j = 0; j < 3; j ++) 135 { 136 k = 0; 137 int[] newAnswer = new int[9]; 138 for(int m = i * 3; m < i * 3 + 3; m ++) 139 { 140 for(int n = j * 3; n < j * 3 + 3; n ++) 141 { 142 newAnswer[k] = answer[m][n]; 143 k++; 144 } 145 } 146 if(judge9(newAnswer) == false) 147 { 148 return false; 149 } 150 } 151 } 152 return true; 153 } 154 public static boolean judge9(int[] answer) 155 { 156 int i,j; 157 for(i = 0; i < 9; i ++) 158 { 159 for(j = 0; j < 9; j ++) 160 { 161 if(i == j) 162 continue; 163 if(answer[i] == answer[j]) //如果有重复的数字，返回false 164 { 165 return false; 166 } 167 } 168 } 169 return true; //没有重复数字，返回true 170 } 171 172 public static void main(String[] args) { 173 JFrame frame = new ShuDu(); 174 frame.setTitle("软件工程数独求解"); 175 frame.setSize(600,700); 176 frame.setLocationRelativeTo(null); 177 frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 178 frame.setVisible(true); 179 } 180 } 181 class explainListenerClass implements ActionListener{ //事件监听器 182 public void actionPerformed(ActionEvent e){ 183 JOptionPane.showMessageDialog(null, "填入数字保证每行每列及每个小的九宫格内数字无重复","Explain",JOptionPane.INFORMATION_MESSAGE); 184 } 185 } 186 class messageListenerClass implements ActionListener{ 187 public void actionPerformed(ActionEvent e){ 188 JOptionPane.showMessageDialog(null, "made by wyx","Message",JOptionPane.INFORMATION_MESSAGE); 189 } 190 }
2、后端处理如下

3、程序界面如下
4、程序分析：本次作业基于上一次的数独作业，改正了数独生成个数0<N<1000000，并且代码已上传至conding,

5、学习心得
本次处理根据上一次老师点评的要求，有了较大的改进，但还是有很多的地方不是很懂，为此，进行了较长时间的学习，特别是添加GUI设计界面，还是事件监控等，本次程序设计并不是完全由个人开发，很大程度是参考他人代码而实现
