本文实例为大家分享了java实现打印日历的具体代码，供大家参考，具体内容如下
效果图
代码：
//引入Scanner类，用于从控制台输入年月
import java.util.Scanner;
//程序开始
class Rili{
//主方法，程序执行的入口
public static void main(String[] args){
inputYearAndMonth();
}
public static void inputYearAndMonth(){
Scanner sc = new Scanner(System.in);
System.out.println("请输入年");
int year = sc.nextInt();
System.out.println("请输入月");
int month = sc.nextInt();
printRiLi(year , month);
}
public static void printRiLi(int year,int month){
//一周七天，定义一个计数器，打印一天加1（包括空白）如果%7等于0的话就需要换行
int count = 0;
System.out.println("t---下面打印的是："+year+"年"+month+"月的日历表---");
System.out.println();
System.out.println("星期一t星期二t星期三t星期四t星期五t星期六t星期日");
for(int i = 1;i <= getSpace(year,month);i++){
System.out.print("t");
count +=1;
}
for(int i = 1;i <= getDaysOfMonth(year ,month);i++){
System.out.print(i+"t");
count +=1;
if(count % 7 ==0){
System.out.println();
}
}
}
public static boolean isLoopYear(int year){
return (year %4 ==0 && year % 100 !=0) || (year % 400 == 0);
}
public static int getDaysOfMonth(int year ,int month){
int days = 0;
switch(month){
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
case 12:
days = 31;
break;
case 4:
case 6:
case 9:
case 11:
days = 30;
break;
case 2:
days = isLoopYear(year)? 29:28;
break;
}
return days;
}
public static int getTotalDays(int year , int month){
int daysofyear = 0;
int daysofmonth = 0;
for(int i = 1900;i < year;i++){
daysofyear += isLoopYear(i)? 366:365;
}
for(int i = 1; i < month; i++){
daysofmonth += getDaysOfMonth(year,i);
}
return daysofyear+daysofmonth;
}
public static int getSpace(int year,int month){
int allSpace = getTotalDays(year,month) % 7;
return allSpace;
}
}
