本文实例为大家分享了Java打印指定年月日历的具体代码，供大家参考，具体内容如下
日历如下：
程序如下：
//打印指定年月的日历public class PrintCalendar { public static void main(String[] args) { int year=2013; int month=12; printMonth(year,month); } private static void printMonth(int year, int month) {//打印日历 printMonthTitle(year,month); printMonthBody(year,month); } private static void printMonthTitle(int year, int month) {//打印日历标题 System.out.println(" "+getMonthName(month)+" "+year); System.out.println("------------------------------"); System.out.println(" Sun Mon Tue Wed Thu Fri Sat"); } private static String getMonthName(int month) { String monthName=null; switch(month){ case 1:monthName="January";break; case 2:monthName="February";break; case 3:monthName="March";break; case 4:monthName="April";break; case 5:monthName="May";break; case 6:monthName="June";break; case 7:monthName="July";break; case 8:monthName="August";break; case 9:monthName="September";break; case 10:monthName="October";break; case 11:monthName="November";break; case 12:monthName="December"; } return monthName; } public static boolean isLeapYear(int year){//判断是否为闰年 return year%400==0||(year%4==0&&year%100!=0); } public static int getNumberOfDaysInMonth(int year,int month){//获取对应月份天数 if(month==1||month==3||month==5||month==7||month==8||month==10||month==12) return 31; if(month==4||month==6||month==9||month==11) return 30; if(month==2) return isLeapYear(year)?29:28; return 0; } public static int getTotalNumberOfDays(int year,int month){//获取从1800年到当月的总天数 int total=0; for(int i=1800;i<year;i++){ if(isLeapYear(i)) total=total+366; else total=total+365; } for(int i=1;i<month;i++) total=total+getNumberOfDaysInMonth(year,i); return total; } public static int getStartDay(int year,int month){//获得当月第一天是星期几 int startDay1800=3; int totalNumberOfDays=getTotalNumberOfDays(year,month); return (totalNumberOfDays+startDay1800)%7; } public static void printMonthBody(int year,int month){//打印日历体 int startDay=getStartDay(year,month); int numberOfDaysInMonth=getNumberOfDaysInMonth(year,month); for(int i=0;i<startDay;i++){ System.out.print(" "); } for(int i=1;i<=numberOfDaysInMonth;i++){ if(i<10) System.out.print(" "+i); else System.out.print(" "+i); if((i+startDay)%7==0) System.out.println(); } System.out.println(); }}
