日历程序java代码 java编程实现日历记事本

javaIT技术

求Java 日历的小程序的源代码也不知道你具体需求是什么，以前改过一个日历程序，一共四个java类，放在同一个包里 。经测试可以运行 。
//Start.java
import java.awt.*;
import javax.swing.*;
class Start{
public static void main(String [] args){
DateFrame frame=new DateFrame();
frame.setLocationRelativeTo(frame);
frame.setResizable(false);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
//DateInfo.java
import java.util.*;
public class DateInfo{
private int mYear, mMonth;
private int mDayOfMonth, mFristWeek;
public DateInfo(int year, int month) throws DateException{
mYear = year;
if (month0 || month12){
throw (new DateException());
}
mMonth = month;
mDayOfMonth = getDayOfMonth(mYear, mMonth);
mFristWeek = getFristWeek(mYear, mMonth);
}
private int getDayOfMonth(int year, int month){
int[][] ary = {{0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31},
{0, 31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}};
return (ary[isLeapYear(year)][month]);
}
private int isLeapYear(int year){
if (year % 4 == 0year % 100 != 0 ||year % 400 == 0){
return (1);
}
else{
return (0);
}
}
private int getFristWeek(int year, int month){
java.util.Calendar cal = Calendar.getInstance();
cal.set(year, month - 1, 1);
return (cal.get(Calendar.DAY_OF_WEEK) - 1);
}
public String toString(){
String str;
str = "\t\t"mYear"年"mMonth"月\n";
str= "日\t一\t二\t三\t四\t五\t六\n";
int i;
for (i = 1; i = mFristWeek; i){
str= " \t";
}
for (int j = 1; j = mDayOfMonth; j, i){
str=j "\t";
if (i % 7 == 0){
str= "\n";
}
}
return (str);
}
}

【日历程序java代码 java编程实现日历记事本】}
catch (Exception ex) {
ex.printStackTrace();

//DateException.java
public class DateException extends Exception{
public DateException(){

}
}
显示系统当前日历和查询日历，java代码，亲们，MainFrame.java是显示日历程序，Clock.java是日历计算程序（可以不要） 。
编译后运行MainFrame这个类即可 。
swing窗口显示万年历 ， jdk1.4以上环境编译运行 。
package
org.test;import
java.awt.BorderLayout;import
java.awt.Color;import
java
怎么用java写日历以下是两个类日历程序java代码，请楼主分别存成两个java文件:
其中
MainFrame.java是显示日历程序日历程序java代码，Clock.java是日历计算程序 。编译后运行MainFrame这个类即可 。
