使用Java中LocalDate写的日历

package CalendrTest;

import java.time.DayOfWeek;
import java.time.LocalDate;


public class Calendar {
    public static void main(String[] args) {
        //获取一个对象
        LocalDate date = LocalDate.now();
        System.out.println("当前的日期 : " + date);
        //获取当前月份天数，和几月份
        int month = date.getMonthValue();
        int today = date.getDayOfMonth();
        //将当前对象设置为本月第一天，并获取第一天是周几
        date = date.minusDays(today - 1);
        DayOfWeek dayOfWeek = date.getDayOfWeek();
        int value = dayOfWeek.getValue();//周一为 1 ， ... , 周天为 7

        System.out.println("一" + "t" + "二" + "t" + "三" + "t" + "四" + "t" + "五" + "t" + "六" + "t" + "七");
        for(int i = 1 ; i < value ; i++){
            System.out.print(" t");
        }
        while(date.getMonthValue() == month){
            System.out.printf("%2d" , 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();
        }

    }

}
