一个简单的万年历制作

简单介绍万年历的各功能实现：

1.首先键盘输入查询的年份和月份

        Scanner sc = new Scanner(System.in);System.out.println("请输入年份");int year = sc.nextInt();System.out.println("请输入月份");int month = sc.nextInt();//判断年月是否输入正确         while(year<1900){ System.out.println("你输入的年份不正确，请重新输入年份");     year = sc.nextInt();}while(month>12||month<=0){ System.out.println("你输入的月份不正确，请重新输入月份");     month = sc.nextInt();}

2.然后对该年份的属性进行判断（平年or闰年）：

//判断该年是闰年还是平年public static boolean YearType(int year){if ((year%4==0 &&year%100!=0)||year%400==0){return true;}else{return false;}}

3.对输入年份每个月的天数进行判断

//判断该年每个月的天数    public static int day(int month,int year){if(month==4||month==6||month==9||month==11){return 30;}else if(month==2){if(YearType(year)){return 29;}else{return 28;}}else{return 31;}}

4.打印日历表

public static void WeekTable(int month,int year,int dayall,int monthday){//System.out.println("日\t"+"一\t"+"二\t"+"三\t"+"四\t"+"五\t"+"六\t");for(int i=0;i<=day(month,year)+(dayall+monthday)%7;i++){if(i<=(dayall+monthday)%7){System.out.print("\t");}else{System.out.print((i-(dayall+monthday)%7)+"\t");}if((i+1)%7==0&&i!=0){System.out.println();}}}

5.对以上进行整合，最后附上源代码：

import java.util.Scanner;class Calendar {public static void main(String[] args) {System.out.println("欢迎进入万历表查询系统");System.out.println("---------------------------------------------------");boolean button=true;while(button!=false){Input();System.out.println("输入'true'继续查询，'false'退出系统！");Scanner sc = new Scanner(System.in);    button=sc.nextBoolean();if(!button){System.out.println("谢谢你的使用，再见！");}}}public static void Input(){int dayall=0,monthday=0;Scanner sc = new Scanner(System.in);System.out.println("请输入年份");int year = sc.nextInt();         while(year<1900){ System.out.println("你输入的年份不正确，请重新输入年份");     year = sc.nextInt();}        System.out.println("请输入月份");int month = sc.nextInt();while(month>12||month<=0){ System.out.println("你输入的月份不正确，请重新输入月份");     month = sc.nextInt();}for (int i=1900+1;i<=year;i++){if(YearType(i)){dayall+=366;//System.out.println("闰年");}else{dayall+=365;//System.out.println("平年");}}for (int i=1;i
