第4次作业类测试代码+020+梁睿阳

一、类图

二、代码与界面

因为有很大一部分代码是旧的并没有做更改，本次试验只是新增了几个类。

为了实现weekDay功能,利用了Kim Larsson calculation formula，可以很方便得通过公式计算出星期

 1 public static int weekDay(int y,int m,int d)
 2     {
 3         if(m==1||m==2) 
 4         {
 5             m+=12;
 6             y--;
 7         }
 8         int iWeek = (d+2*m+3*(m+1)/5+y+y/4-y/100+y/400)%7;
 9         switch(iWeek){
10             case 0: return 1;
11              case 1: return 2;
12              case 2: return 3;
13              case 3: return 4;
14              case 4: return 5;
15              case 5: return 6;
16              case 6: return 7;
17         }
18         return 0;
19     }

此外，还实现了lastday

 1 public static String lastdate(int y,int m,int d)
 2     {
 3         month[2]=28;
 4         if(checkLeapYear(y)==1)
 5         {
 6             month[2]=29;
 7         }
 8         switch (checkVal(y,m,d))
 9         {
10             case 1:
11                 return "月份超出范围";
12             case 2:
13                 return "日期超出范围";
14             case 3:
15                 return "年份超出范围";
16             default:
17                 if(d>1)
18                 {
19                     return getString(y, m, d-1);
20                 }
21                 if(d==1)
22                 {
23                     if(checkFirstday(y, m, d)==1)
24                     {
25                         return getString(y-1, 12, 31);
26                     }
27                     else
28                     {
29                         return getString(y, m-1, month[m-1]);
30                     }
31                 }
32                 return "程序错误";
33         }
34     }

界面部分主要任务就是使用上面写好的类，以及控制合法输入的问题：

限制只允许输入数字的核心代码：

 1 inputDay.addKeyListener(new KeyAdapter(){
 2             public void keyTyped(KeyEvent e) {
 3                 int keyChar = e.getKeyChar();                
 4                 if(keyChar >= KeyEvent.VK_0 && keyChar <= KeyEvent.VK_9){
 5                     
 6                 }else{
 7                     e.consume(); 
 8                 }
 9             }
10         });

OK按钮的动作：

 1 JButton okButton = new JButton("OK");
 2         okButton.addActionListener(new ActionListener() {
 3             @Override
 4             public void actionPerformed(ActionEvent e)
 5             {
 6                 //get input info
 7                 String s_y = inputYear.getText();
 8                 String s_m = inputMonth.getText();
 9                 String s_d = inputDay.getText();
10                 //parse String to Int 
11                 int y = Integer.parseInt(s_y);
12                 int m = Integer.parseInt(s_m);
13                 int d = Integer.parseInt(s_d);
14                 //get next day
15                 String outputNextday = run.nextdate(y, m, d);
16                 System.out.println(outputNextday);
17                 String ans_first=(String) outputNextday.subSequence(0, 1);
18                 System.out.println(ans_first);
19                 if(isNumeric(ans_first)==true)
20                 {
21                     nextdayOutput.setText(outputNextday);
22                     //get previous day
23                     String outputLastday = run.lastdate(y, m, d);
24                     lastdayOutput.setText(outputLastday);
25                     //get week day
26                     int weekday = run.weekDay(y, m, d);
27                     weekdayOutput.setText(String.valueOf(weekday));
28                 }
29                 else
30                 {
31                     //pop up a waring window
32                     JOptionPane.showMessageDialog(null, "输入有误，请重请输入正确整数");
33                     //clear all input blocks
34                     inputYear.setText("");
35                     inputMonth.setText("");
36                     inputDay.setText("");
37                     lastdayOutput.setText("");
38                     nextdayOutput.setText("");
39                     weekdayOutput.setText("");
40                 }
41             }
42         });

Cancel按钮的动作：

 1 JButton cancelButton = new JButton("Cancel");
 2         cancelButton.addActionListener(new ActionListener() {
 3             @Override
 4             public void actionPerformed(ActionEvent e) {
 5                 //shutdown application
 6                 inputYear.setText("");
 7                 inputMonth.setText("");
 8                 inputDay.setText("");
 9                 lastdayOutput.setText("");
10                 nextdayOutput.setText("");
11                 weekdayOutput.setText("");
12             }
