Java实现简单的万年历
Java实现简单的万年历本⽂实例为⼤家分享了Java实现简单万年历的具体代码，供⼤家参考，具体内容如下1 要求1、输⼊年份；2、输⼊⽉份；3、输出某年某⽉的⽇历。
2 思路1、实现从控制台接收年和⽉，判断是否是闰年（判断是否是闰年：能被4整除但不能被100整除；或者能被400整除）；2、计算输⼊⽉份的天数；3、计算该⽉第⼀天是星期⼏；3.1 计算输⼊年份距离1900年1⽉1⽇的天数；3.2 计算输⼊⽉份之前的天数（从当年年初开始）；3.3 将以上两组数据进⾏求和；3.4 已知该⽉之前的天数，计算输⼊⽉份的第⼀天是星期⼏（从1900年1⽉1⽇(星期⼀)开始推算: 星期⼏ = 1 + 天数差 % 7 ）。
4、按格式输出该⽉⽇历。

044Java编程判断用户输入月份所属的季节
Java编程判断用户输入月份所属的季节 题目描述本实例根据用户输入的月份来判断所属季节，这是一个很典型的应用switch语法的例子，通过本实例，希望读者可以很好地体会switch语句的使用技巧，本实例的运行结果如图4.10所示。
图4.10 判断月份所属季节技术指导本实例是一个典型的switch语句应用的实例，在判断月份属于哪个季节时，应该知道3～5月份属于春季，6～8月份属于夏季，9～11月份属于秋季，12月份至第二年的2月份属于冬季。
程序代码如下：package p94判断用户输入月份所属的季节;import java.util.Scanner;public class JudgeMonth {public static void main(String[] args) {Scanner scan=new Scanner(System.in); //创建扫描器// 提示用户输入月份System.out.println("请输入一个月份，我能告诉你它属于哪个季节。

java常用的当前时间获取方法
1:import java.util.*;int y,m,d,h,mm;Calendar c = Calendar.getInstance();y = c.get(Calendar.YEAR); //年m = c.get(Calendar.MONTH) + 1; //月d = c.get(Calendar.DAY_OF_MONTH); //日h = c.get(Calendar.HOUR); //时12小时制h2 = c.get(Calendar.HOUR_OF_DAY);//时24小时制mm = c.get(Calendar.MINUTE); //分2:java.util.Date d = new java.util.Date();java.text.SimpleDateFormat dformat = new java.text.SimpleDateFormat("yyyy-MM-dd"); String datetime = dformat.format(d);System.out.println(datetime);3:import java.util.*; import java.text.*;Date now = new Date();DateFormat defaultFormat =DateFormat.getDateInstance();DateFormat shortFormat =DateFormat.getDateInstance(DateFormat.SHORT); DateFormat mediumFormat =DateFormat.getDateInstance(DateFormat.MEDIUM); DateFormat longFormat =DateFormat.getDateInstance(DateFormat.LONG); DateFormat fullFormat =DateFormat.getDateInstance(DateFormat.FULL); String defaultDate = defaultFormat.format(now); String shortDate = shortFormat.format(now); String mediumDate = mediumFormat.format(now); String longDate = longFormat.format(now);String fullDate = fullFormat.format(now);System.out.println("(Default) Today :" + defaultDate);System.out.println("(SHORT) Today : " + shortDate); System.out.println("(MEDIUM) Today :" + mediumDate);System.out.println("(LONG) Today : " + longDate); System.out.println("(FULL) Today : " + fullDate);4.如果只要年月日,可以用subString()截取. 或者用这个String time=newSimpleDateFormat("yyyy-MM-dd").format(Calendar.g etInstance().getTime);5.Date currentTime = new Date(); SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");String dateString = formatter.format(currentTime); dataString 的格式就是2007-03-08这类型其他几种:一. 获取当前系统时间和日期并格式化输出:import java.util.Date;import java.text.SimpleDateFormat;public class NowString {public static void main(String[] args) {SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//设置日期格式System.out.println(df.format(new Date()));// new Date()为获取当前系统时间}}二. 在数据库里的日期只以年-月-日的方式输出，可以用下面两种方法：1、用convert()转化函数：String sqlst = "select convert(varchar(10),bookDate,126) as convertBookDate from roomBook where bookDate between '2007-4-10' and '2007-4-25'"; System.out.println(rs.getString("convertBookDate"));2、利用SimpleDateFormat类：先要输入两个java包：import java.util.Date;import java.text.SimpleDateFormat;然后：定义日期格式：SimpleDateFormat sdf = new SimpleDateFormat(yy-MM-dd); sql语句为：String sqlStr = "select bookDate from roomBook where bookDate between '2007-4-10' and '2007-4-25'";输出：System.out.println(df.format(rs.getDate("bookDate")));************************************************************java中获取当前日期和时间的方法import java.util.Date;import java.util.Calendar;import java.text.SimpleDateFormat;public class TestDate{public static void main(String[] args){Date now = new Date();SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/ddHH:mm:ss");//可以方便地修改日期格式String hehe = dateFormat.format( now );System.out.println(hehe);Calendar c = Calendar.getInstance();//可以对每个时间域单独修改int year = c.get(Calendar.YEAR);int month = c.get(Calendar.MONTH);int date = c.get(Calendar.DATE);int hour = c.get(Calendar.HOUR_OF_DAY);int minute = c.get(Calendar.MINUTE);int second = c.get(Calendar.SECOND);System.out.println(year + "/" + month + "/" + date + " " +hour + ":" +minute + ":" + second);}}有时候要把String类型的时间转换为Date类型，通过以下的方式，就可以将你刚得到的时间字符串转换为Date类型了。
