【Java用法】使用Java编写一个日历格式的方法

public class TestController {
    public static void main(String[] args) {
        LocalDate date = LocalDate.now();
        int month = date.getMonthValue();
        int today = date.getDayOfMonth();
        date = date.minusDays(today - 1);
        DayOfWeek weekDay = date.getDayOfWeek();
        int value = weekDay.getValue();
        System.out.println("Mon Tue Wed Thu Fri Sat Sun");
        for (int i = 1; i < value; i++) {
            System.out.println(" ");
        }
        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();
            }
        }
        if (date.getDayOfWeek().getValue() != 1){
            System.out.println();
        }
    }
}
