（1）实现lastdate方法

 1 public String LastDate(int year, int month, int day)
 2     {
 3         String lastdate = null;
 4         if(month==3)  //2月
 5         {
 6             if(((year%4==0&&year%100!=0)||year%400==0)) //闰年时的2月
 7             {        
 8                     if(day==1)
 9                     {
10                         day=29;
11                         month--;
12                     }
13                     else
14                     {
15                         day--;
16                     }
17             }
18             else
19             {
20                 if(day==1)
21                 {
22                     day=28;
23                     month--;
24                 }
25                 else
26                 {
27                     day--;
28                 }
29             }
30         }
31         else if(month==1)  //12月份
32         {
33             if(day==1)
34             {
35                 year--;    
36                 day=31;
37                 month=12;
38             }
39             else
40             {
41                 day--;
42             }
43         }
44         //一般月份
45         else
46         {
47             if(month==5||month==7||month==10||month==12)
48             {        
49                 if(day==1)
50                 {
51                     month--;
52                     day=30;
53                 }
54                 else
55                 {
56                     day--;
57                 }
58             }
59             else
60             {
61                 if(day==1)
62                 {
63                     month--;
64                     day=31;
65                 }
66                 else
67                 {
68                     day--;
69                 }
70             }
71         }
72         lastdate =  "" + year + "年" + "" + month + "" + "月" + day + "日"  ;
73         return lastdate;
74     }

（2）实现weekday方法

 1 public int weekDay(int year, int month, int day)
 2     {
 3         int num = 0;
 4         //蔡勒公式
 5         if(month==1||month==2)
 6         {
 7             month+=12;
 8             year-=1;
 9         }
10         int c = year/100;
11         year = year - c * 100;
12         num = (year + year/4 + c/4 - 2*c + 26*(month + 1) / 10 + day-1)%7 ;
13         if(num==0)
14         {
15             num+=7;
16         }
17         return num;
18     }

（3）OK按钮实现功能

 1 JButton btnNewButton = new JButton("OK");
 2         btnNewButton.addActionListener(new ActionListener() {
 3             public void actionPerformed(ActionEvent e) {
 4                 Date date = new Date();
 5                 String t_y = textField.getText();
 6                 String t_m = textField_1.getText();
 7                 String t_d = textField_2.getText();
 8                 
 9                 int year = Integer.parseInt(t_y);
10                 int month = Integer.parseInt(t_m);
11                 int day = Integer.parseInt(t_d);
12                 String msg1 = date.NextDate(year,month,day);
13                 String msg2 = date.LastDate(year,month,day);
14                 int weeki = date.weekDay(year,month,day);
15                 String msg = null;
16                 msg = date.Check(year, month, day);
17                 if(msg!=null)
18                 {
19                     JOptionPane.showMessageDialog(null,  msg, "警告！", JOptionPane.ERROR_MESSAGE);
20                     textField.setText("");
21                     textField_1.setText("");
22                     textField_2.setText("");
23                     textField_3.setText("");
24                     textField_4.setText("");
25                     textField_5.setText("");
26                 }
27                 else
28                 {
29                     textField_4.setText(msg1);
30                     textField_5.setText(msg2);
31                     textField_3.setText(String.valueOf(weeki));
32                 }    
33             }
34         }
35         );
36         
37         btnNewButton.setBounds(97, 158, 113, 27);
38         getContentPane().add(btnNewButton);

（4）限制输入只能是数字

 1 textField.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(); //关键，屏蔽掉非法输入  
 8                 }  
 9             }  
10         });  
11         
12         textField_1.addKeyListener(new KeyAdapter(){  
13             public void keyTyped(KeyEvent e) {  
14                 int keyChar = e.getKeyChar();                 
15                 if(keyChar >= KeyEvent.VK_0 && keyChar <= KeyEvent.VK_9){  
16                       
17                 }else{  
18                     e.consume(); //关键，屏蔽掉非法输入  
19                 }  
20             }  
21         });  
22         
23         textField_2.addKeyListener(new KeyAdapter(){  
24             public void keyTyped(KeyEvent e) {  
25                 int keyChar = e.getKeyChar();                 
26                 if(keyChar >= KeyEvent.VK_0 && keyChar <= KeyEvent.VK_9){  
27                       
28                 }else{  
29                     e.consume(); //关键，屏蔽掉非法输入  
30                 }  
31             }  
32         });

（5）Cancle按钮的功能

 1 JButton btnNewButton_1 = new JButton("Cancle");
 2         btnNewButton_1.addActionListener(new ActionListener() {
 3             public void actionPerformed(ActionEvent e) {
 4                 textField.setText("");
 5                 textField_1.setText("");
 6                 textField_2.setText("");
 7                 textField_3.setText("");
 8                 textField_4.setText("");
 9                 textField_5.setText("");
10             }
11         });
12         btnNewButton_1.setBounds(331, 158, 113, 27);
13         getContentPane().add(btnNewButton_1);

（6）全部代码：

  2     public String Check(int year, int month, int day)
  3     {
  4         String msg = null;

  8             return msg;
  9         }
 10         if((month<1||month>12))  // 判断月份是否超出
