Java公历转农历工具类

Java公历转农历工具类

       关于java公历转为农历的工具类网上有很多，大体都来自于同一份源码，但是这些源码仍不能满足项目要求，没有提供时辰的干支形式，所以亲自动手根据项目需求修改了源码，分享给大家，有问题的地方还请各位指正。

 运行结果：

使用该工具类编写一个简单的日历：

import java.util.Calendar;public class GradView {private int[] data1;private String[] data2;public GradView(int year, int month) {Calendar calendar = Instance();calendar.set(year, month - 1, 1);// 当月1日init(calendar);}private void init(Calendar calendar) {int weekOfFirstDay = (Calendar.DAY_OF_WEEK);// 第一天的星期data1 = new int[42];data2 = new String[42];Lauar lauar;calendar.add(Calendar.DATE, -(weekOfFirstDay - 1));for (int i = 0; i < data1.length; i++) {data1[i] = (Calendar.DAY_OF_MONTH);lauar = new Lauar(calendar);String data;if (null != (data = LunarHoliday())) {data2[i] = data;} else if (null != (data = Holiday())) {data2[i] = data;} else if (null != (data = SoralTerm())) {data2[i] = data;} else {data2[i] = LunarDayOfMonth();if ("初一".equals(data2[i])) {data2[i] = LunarMonth();}}calendar.add(Calendar.DATE, 1);}}public static void main(String[] args) {GradView view = new GradView(2015, 2);for (int i = 0; i < view.data1.length; i++) {System.out.print(view.data1[i] + ".");System.out.print(view.data2[i] + "t");if ((i + 1) % 7 == 0)System.out.println();}}}

 运行结果：
