打印本月日期：
代码语言：javascript复制package com.javatest.datetest;
import java.time.*;
/*
* @version 1.0
* @author Tan name
* 该类功能可实现打印本月的日期
*/
public class DateTest {
public static void main(String[] args) {
//创建date对象
LocalDate date = LocalDate.now();
//获取月份
int month = date.getMonthValue();
//获取日期
int today = date.getDayOfMonth();
//将日期调整为每月的第一天
date = date.minusDays(today - 1);
//创建weekday对象
DayOfWeek weekday = date.getDayOfWeek();
//返回获取1-7的数字代表礼拜一到礼拜天
int value = weekday.getValue();
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("=",date.getDayOfMonth());
if (date.getDayOfMonth() == today) {
System.out.print("*");
}
