如何用java语言 写出一个万年历呢? 要求自己输入年份 自动出现月 日 以及对应的星期

如果要月历,只要把月份循环那里修改下,直接调用月历方法既可

import java.text.DateFormatSymbols;

import java.util.Calendar;

import javax.swing.JOptionPane;

public class YearCalendar {

public static void main(String[] args) {

final String title = getCalTitle();

String input = JOptionPane.showInputDialog("Please input year");

try{

if(!input.trim().matches("^\\d{4}$")){

throw new NumberFormatException();

}

int year = Integer.parseInt(input.trim());

System.out.println("------- Calendar For Year " + year + " ----------------");

String[] monthTitles = new DateFormatSymbols().getMonths();

for(int month = Calendar.JANUARY; month = Calendar.DECEMBER; month++){

System.out.println("\t********** " + monthTitles[month] + " *********");

System.out.println(title);

generateMonthlyCalendar(year, month);

System.out.println("\n\n");

}

}catch(NumberFormatException nbFmtExp){

JOptionPane.showMessageDialog(null, "Error data foramt! Date should be 4 digits only format yyyy");

System.exit(0);

}

}

private static String getCalTitle() {

StringBuffer sb = new StringBuffer();

String[] ary = new DateFormatSymbols().getShortWeekdays();

for(int i = Calendar.SUNDAY; i = Calendar.SATURDAY; i++){

sb.append(ary[i]+ "\t");

}

return sb.toString();

}

private static void generateMonthlyCalendar(int year, int month) {

Calendar cal = Calendar.getInstance();

cal.set(Calendar.YEAR, year);

cal.set(Calendar.MONTH, month);

cal.set(Calendar.DATE, 1);

int maxDay = cal.getActualMaximum(Calendar.DAY_OF_MONTH);

int i = 0;

for(i = Calendar.SUNDAY; i cal.get(Calendar.DAY_OF_WEEK); i++){

System.out.print(" \t");

}

while(cal.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY){

System.out.print(cal.get(Calendar.DATE) + "\t");

cal.add(Calendar.DATE, 1);

}

int weekDay = Calendar.SATURDAY;

int day = cal.get(Calendar.DATE);

while(day = maxDay){

if(weekDay == Calendar.SATURDAY){

System.out.println();

weekDay = Calendar.SUNDAY;

}else{

weekDay++;

}

System.out.print(day++ + "\t");

}

}

}

/*

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
