java做日历

‘壹’ 用java做一个日历 要求月份大于12过小于0是进行异常处理

packagecom;

importjava.util.Calendar;
importjava.util.Date;
importjava.util.Scanner;

publicclassMyCalendar
{
	publicstaticvoidmain(String[]args)
	{
		Scannerscanner=newScanner(System.in);
		Stringreg="^(\d+)[^\d]+((0?[1-9])|(1[012]))$";
		while(true)
		{
			System.out.println("输入年月(年和月用非数字隔开:如2015.1)(什么都不输入直接退出)");
			Stringline=scanner.nextLine().trim();
			if("".equals(line))
			{
				scanner.close();
				break;
			}
			if(!line.matches(reg))
			{
				continue;
			}
			intyear=Integer.parseInt(line.replaceAll(reg,"$1"));
			intmonth=Integer.parseInt(line.replaceAll(reg,"$2"));
			System.out.println("日	一	二	三	四	五	六");
			Calendarcalendar=Calendar.getInstance();
			//这个月的1号是星期几
			calendar.set(year,month-1,1);
			intday=calendar.get(Calendar.DAY_OF_WEEK);
			intstart=Calendar.SUNDAY;
			calendar.add(Calendar.DATE,-day+start);
			while(start<day)
			{
				System.out.print(calendar.get(Calendar.DATE)+"	");
				calendar.add(Calendar.DATE,1);
				start++;
			}
			calendar.set(year,month-1,1);
			Datenow=calendar.getTime();
			calendar.set(year,month,1);
			Datenext=calendar.getTime();
			for(Datecur=now;cur.before(next);)
			{
				calendar.setTime(cur);
				System.out.print(calendar.get(Calendar.DATE)+"	");
				if(calendar.get(Calendar.DAY_OF_WEEK)==Calendar.SATURDAY)
				{
					System.out.println();
				}
				calendar.add(Calendar.DATE,1);
				cur=calendar.getTime();
			}
			calendar.add(Calendar.DATE,-1);
			intto=calendar.get(Calendar.DAY_OF_WEEK);

‘叁’ 如何用JAVA写日历

按照你的要求编写的Java日历验证程序如下

UI.java

importjava.util.Scanner;
publicclassUI{
staticScannersc=newScanner(System.in);
publicstaticintaskInt(Strings){
System.out.print(s);
returnsc.nextInt();
}
publicstaticvoidprintln(Strings){
System.out.println(s);
}
}

EE.java

publicclassEE{
publicvoidvalidateDateCore(){
intyear=UI.askInt("Entertheyear:");
intmonth=UI.askInt("Enterthemonth:");
intday=UI.askInt("Entertheday:");
if(year<1){
UI.println("Theyearisnotavalidnumber.");
return;
}
if(month<1||month>12){
UI.println("Themonthisnotavalidnumber.");
return;
}
intmonthDay=0;
switch(month){
case1:
case3:
case5:
case7:
case8:
case10:
case12:monthDay=31;break;
case4:
case6:
case9:
case11:monthDay=30;break;
case2:
if((year%4==0&&year%100!=0)||year%400==0){
monthDay=29;
}else{
monthDay=28;
}
break;
}
if(day<1||day>monthDay){
UI.println("Thedayisnotavalidnumber.");
return;
}else{
UI.println("Itis"+day+"/"+month+"/"+year+".");
}
}
publicstaticvoidmain(String[]args){
newEE().validateDateCore();
}
}

运行结果

}

//1900.1.1是星期一，取余得1234560分别代表星期一到星期天
returndaysFromNovecento(day,month,year)%7;
}

/**

System.out.println();
}
System.out.println();
}

/**

‘柒’ java编写日历

我给你贴上我在java核心技术中看到的代码吧,当然没有输入年份和月份,是按照当前时间创建的,写有我写的注释,应该能看的懂

/*
* 2012年5月13日10:37:58
* 日历程序
* Function:
* 显示当前月份的日历
* 总结
* 1. 0-11分别代表1-12月
* 1-7分别代表周日-周六
* 2. 使用GregorianCalendar对象的get方法（参数）获取月，日，年等信息
* 3.
*/
import java.text.DateFormatSymbols;
import java.util.*;

public class CalendarTest {
public static void main(String[] args) {
//construct d as current date构造一个日期
GregorianCalendar d = new GregorianCalendar();

//获取今天是这个月的第几天
int today = d.get(Calendar.DAY_OF_MONTH); //Calendar.DAY_OF_MONTH作为参数调用，得到今天是这个月的第几天
int month = d.get(Calendar.MONTH); //月份

d.set(Calendar.DAY_OF_MONTH, 1); //设置d的日期是本月的1号
int weekDay = d.get(Calendar.DAY_OF_WEEK); //获取当天位于本星期的第几天，也就确定了星期几，值的范围是1-7
int firstDayOfWeek = d.getFirstDayOfWeek(); //获取一星期的第一天,我们得到的是Calendar.SUNDAY,因为我们一星期的第一天是周日

int indent = 0; //为了定位本月第一天，定义索引
while (weekDay != firstDayOfWeek) {
//注意，月份用0-11代表1-12月，为了清晰起见，使用常量代替，下面获取月份得到的实际是当前月-1的值，所以我们要加1
//System.out.printf("当前星期的第%d天,位于当月的第%d天, 现在是%d月\n",
// weekDay, d.get(Calendar.DAY_OF_MONTH), d.get(Calendar.MONTH)+1); //Test Code

indent++;//缩进个数+1
d.add(Calendar.DAY_OF_MONTH, -1);//当前天数-1，如果现在是1号，则执行本条代码后，时间变为上一个月最后一天
weekDay = d.get(Calendar.DAY_OF_WEEK); //重新获取当天位于本星期的第几天
}

String[] weekDayNames = new DateFormatSymbols().getShortWeekdays();//获取简短形式的星期字符串数组
//System.out.println(weekDayNames.length);getShortWeekdays()得到的数组的长度是8，下标为0的是没有值1为星期日...7为星期六
//注释代码1
//Java核心技术的代码
/*
do {
//System.out.printf("%4s", weekDayNames[weekDay]); //经过上面定义索引，weekDay代表的是本星期日
d.add(Calendar.DAY_OF_MONTH, 1); //天数加1
weekDay = d.get(Calendar.DAY_OF_WEEK); //重新获得weekDay的值
} while (weekDay != firstDayOfWeek); //当循环完一个星期后，这里判断不成立，退出循环
*/
//我写的代码，替换上面注释代码1
for (int i=1; i<weekDayNames.length; i++)//打印星期标题
System.out.printf("%3s\t", weekDayNames[i]);//引号内是一个全角的空格，因为是中文版，不是书上英文环境,中文和空格对于不上,这里我们用\t解决
//System.out.printf("%3s", weekDayNames[i]); //方式2
System.out.println();//换行

for (int i=1; i<=indent; i++)//确定一星期的一天位置，利用上面indent
System.out.printf("\t");//如用方式2，则这里内容是四个全角空格

//实现输出日期
d.set(Calendar.MONTH, month);
d.set(Calendar.DAY_OF_MONTH, 1);
do {
//print day
int day = d.get(Calendar.DAY_OF_MONTH);
System.out.printf("%3d", day);

‘捌’ 如何用java里的Calendar类编写万年历

/*
题目:输出任意年份任意月份的日历表(公元后)
思路:
1.已知1年1月1日是星期日,1%7=1对应的是星期日,2%7=2对应的是星期一,以此类推;
2.计算当年以前所有天数+当年当月1号之前所有天数;
a.年份分平年闰年,平年365天,闰年366天;
b.闰年的判断方法year%400==0||(year%100!=0&&year%4==0)若为真,则为闰年否则为平年;
c.定义平年/闰年数组,包含各月天数;
d.遍历数组求和,计算当年当月前总天数;
e.当年以前所有天数+当年当月前总天数+1即为1年1月1日到当年当月1日的总天数;
3.总天数对7取模,根据结果判断当月1号是星期几,输出空白区域;
4.输出当月日历表,逢星期六换行
