怎么用java寫日歷

以下是兩個類，請樓主分別存成兩個java文件:

目前成都創新互聯公司已為1000+的企業提供了網站建設、域名、網絡空間、網站托管運營、企業網站設計、扶風網站維護等服務，公司將堅持客戶導向、應用為本的策略，正道將秉承"和諧、參與、激情"的文化，與客戶和合作伙伴齊心協力一起成長，共同發展。

其中

MainFrame.java是顯示日歷程序，Clock.java是日歷計算程序。編譯后運行MainFrame這個類即可。

如何用JAVA編寫出一個簡單的日歷

import javax.swing.JOptionPane;

public class NewClass{

public static void main(String[] args){

int year,month;

Calender cal=new Calender(2008,10);

cal.showCalender();

year=Integer.parseInt(JOptionPane.showInputDialog("Year:"));

month=Integer.parseInt(JOptionPane.showInputDialog("Month:"));

cal.setYear(year);

cal.setMonth(month);

cal.showCalender();

}

}

class Calender{

private int year,month;

public Calender(){

year=0;

month=1;

}

public Calender(int year){

this.year=year;

month=1;

}

public Calender(int year,int month){

this.year=year;

if(month12)

this.month=month%12;

else

this.month=month;

}

public void setYear(int year){

this.year=year;

}

public void setMonth(int month){

if(month12)

this.month=month%12;

else

this.month=month;

}

private int dayOfMonth(){

int days=0;

switch(month){

case 1:days=31;break;

case 2:{

if(((year%4==0)(year%100!=0))||(year%400==0))

days=29;

else

days=28;

break;

}

case 3:days=31;break;

case 4:days=30;break;

case 5:days=31;break;

case 6:days=30;break;

case 9:days=30;break;

case 10:days=31;break;

case 11:days=30;break;

default:

}

return days;

}

private int dayOfWeek(){

int Y=year;

int M=month;

int D=1;

int A;

A = Y0?(5+(Y+1)+(Y-1)/4-(Y-1)/100+(Y-1)/400)%7:(5+Y+Y/4-Y/100+Y/400)%7;

if (((Y%4 == 0 Y%100 != 0)|| Y%400 == 0) M2) A =(A+1)%7;

A=(A+D)%7;

return A;

}

public void showCalender(){

String str=new String();

str=" ";

str+=year+"年"+month+"月";

str+="\n\n";

str+="日 一 二 三 四 五 六\n";

int week=this.dayOfWeek();

for(int i=0,j=1;i7;i++){

if(iweek)

str+=" ";

else{

str+=" "+j+" ";

j++;

}

}

str+="\n";

end:

for(int i=7-week+1;i=this.dayOfMonth();){

for(int j=0;j7;j++){

if(i10)

str+=" "+i+" ";

else

str+=i+" ";

i++;

if(ithis.dayOfMonth())

break end;

}

str+="\n";

}

JOptionPane.showMessageDialog(null,str);

}

}

用一個類來實現
