要求：

制作一個日歷表（1990-2999），輸入年月，輸出該月的日歷。

import java.util.Scanner;public class MyCalendar {public void calendarmenu(){while (true){Scanner reader=new Scanner(System.in);System.out.println("輸入年份;1900————2999");int year=reader.nextInt();System.out.println("輸入月份；1————12");int month=reader.nextInt();showCalender(year,month);System.out.println();System.out.println("是否繼續？n-退出,任意鍵繼續");if (reader.next().equals("n")){//reader.close();break;}}}public void showCalender(int year,int month){//日歷表格System.out.println("一\t二\t三\t四\t五\t六\t日");int weekday=getWeekday(year,month,1);for (int i=1;i<weekday;i++){System.out.printf("\t");}int monthDays =getMonthDays(year,month);for(int i=1;i<=monthDays;i++){int k=weekday%7;if(k==0){System.out.printf(i+"\n");}else{System.out.printf(i+"\t");}weekday=weekday+1;}}public int getWeekday(int year,int month,int day){int weekday=0;int sumDays=getSumDays(year,month,day);weekday=sumDays%7;return weekday;}public int getMonthDays(int year,int month){int monthDays=0;if (month==4||month==6||month==9||month==11){monthDays=30;}else if (month==2){if (year%4==0&&year%100!=0||year%400==0){monthDays=29;}else{monthDays=28;}}else {monthDays=31;}return monthDays;}public int getSumDays(int year,int month,int day){int sumDays=0;for (int i=1900;i<year;i++){if (i%4==0&&i%100!=0||i%400==0){sumDays=sumDays+366;}else {sumDays=sumDays+365;}}for (int i=1;i<month;i++){sumDays=sumDays+getMonthDays(year,i);}sumDays=sumDays+day;return sumDays;} }
