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。

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获取年月日的方法Java是一种面向对象的编程语言，广泛应用于软件开发领域。
在Java中，获取年月日是一项常见的操作，可以通过多种方法实现。
下面，我将为大家介绍一些常用的获取年月日的方法，并解释它们的使用方式。
一、使用Java内置的日期类Java提供了多个日期类，其中最常用的是`Date`和`Calendar`类。
这两个类都可以用于获取年月日，但它们的使用方式有所不同。
1. `Date`类`Date`类是`java.util`包中的一个类，可以表示一个特定的时间点。
要获取当前的年月日，可以使用`Date`类的`getYear()`、`getMonth()`和`getDate()`方法。
需要注意的是，`getYear()`方法返回的年份是相对于1900的偏移量，所以需要将其加上1900才能得到真实的年份。
```javaDate currentDate = new Date();int year = currentDate.getYear() + 1900;int month = currentDate.getMonth() + 1;int day = currentDate.getDate();System.out.println("当前日期：" + year + "年" + month + "月" + day + "日");```2. `Calendar`类`Calendar`类是`java.util`包中的一个抽象类，它提供了丰富的日期操作方法。
与`Date`类相比，`Calendar`类更常用，因为它可以处理更复杂的日期计算。
要获取当前的年月日，可以使用`Calendar`类的`get()`方法，并传入相应的`Calendar`字段参数，如`Calendar.YEAR`、`Calendar.MONTH`和`Calendar.DAY_OF_MONTH`。
