public class CalendarTest {
    public static void main(String[] args){
        LocalDate date = LocalDate.now();
 int month = date.getMonthValue();
 int today = date.getDayOfMonth();
 date = date.minusDays(today - 1); // 设置本月起始日期
 DayOfWeek weekday = date.getDayOfWeek();
 int value = weekday.getValue(); // 1:monday ... 7 :sunday
 System.out.println("Mon Tue Wed Thu Fri Sat Sun");
 for(int i = 1; i < value; i++)
            System.out.print("    ");
 while(date.getMonthValue() == month){
            System.out.printf("%3d",date.getDayOfMonth());
 if(date.getDayOfMonth() == today)
                System.out.print("*");
 else System.out.print(" ");
 date = date.plusDays(1);
 if(date.getDayOfWeek().getValue() == 1)
                System.out.println();
