JAVA基础时间类能否支持公历外的历法 各位哥哥姐姐弟弟妹妹们,有谁知道JAVA能操作公历外的其他历法的时间吗,比如说波斯历。我知道JAVA的时间操作类(java.util.Calendar等类)是可以指定时区和语言环境的,但不清楚这个语言环境是否包含了当地使用的历法。是否JAVA基础类只支持公历,要使用其他历法得自己写类? 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 网上有人用java实现了阴历http://www.busfly.cn/csdn/post/684.html所以,我想你说的所谓的其他历法,也是要自己写的吧 转的阴历的,我不明白你说的公历以外的历法指那些。你看看。没用就扔了!import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Date;public class Lunar { private int year; private int month; private int day; private boolean leap; final static String chineseNumber[] = {"正", "二", "三", "四", "五", "六", "七", "八", "九", "十", "十一", "腊"}; final static String chineseNumber1[] = {"一", "二", "三", "四", "五", "六", "七", "八", "九", "十", "十一", "十二"}; static SimpleDateFormat chineseDateFormat = new SimpleDateFormat("yyyy年MM月dd日"); final static long[] lunarInfo = new long[] {0x04bd8, 0x04ae0, 0x0a570, 0x054d5, 0x0d260, 0x0d950, 0x16554, 0x056a0, 0x09ad0, 0x055d2, 0x04ae0, 0x0a5b6, 0x0a4d0, 0x0d250, 0x1d255, 0x0b540, 0x0d6a0, 0x0ada2, 0x095b0, 0x14977, 0x04970, 0x0a4b0, 0x0b4b5, 0x06a50, 0x06d40, 0x1ab54, 0x02b60, 0x09570, 0x052f2, 0x04970, 0x06566, 0x0d4a0, 0x0ea50, 0x06e95, 0x05ad0, 0x02b60, 0x186e3, 0x092e0, 0x1c8d7, 0x0c950, 0x0d4a0, 0x1d8a6, 0x0b550, 0x056a0, 0x1a5b4, 0x025d0, 0x092d0, 0x0d2b2, 0x0a950, 0x0b557, 0x06ca0, 0x0b550, 0x15355, 0x04da0, 0x0a5d0, 0x14573, 0x052d0, 0x0a9a8, 0x0e950, 0x06aa0, 0x0aea6, 0x0ab50, 0x04b60, 0x0aae4, 0x0a570, 0x05260, 0x0f263, 0x0d950, 0x05b57, 0x056a0, 0x096d0, 0x04dd5, 0x04ad0, 0x0a4d0, 0x0d4d4, 0x0d250, 0x0d558, 0x0b540, 0x0b5a0, 0x195a6, 0x095b0, 0x049b0, 0x0a974, 0x0a4b0, 0x0b27a, 0x06a50, 0x06d40, 0x0af46, 0x0ab60, 0x09570, 0x04af5, 0x04970, 0x064b0, 0x074a3, 0x0ea50, 0x06b58, 0x055c0, 0x0ab60, 0x096d5, 0x092e0, 0x0c960, 0x0d954, 0x0d4a0, 0x0da50, 0x07552, 0x056a0, 0x0abb7, 0x025d0, 0x092d0, 0x0cab5, 0x0a950, 0x0b4a0, 0x0baa4, 0x0ad50, 0x055d9, 0x04ba0, 0x0a5b0, 0x15176, 0x052b0, 0x0a930, 0x07954, 0x06aa0, 0x0ad50, 0x05b52, 0x04b60, 0x0a6e6, 0x0a4e0, 0x0d260, 0x0ea65, 0x0d530, 0x05aa0, 0x076a3, 0x096d0, 0x04bd7, 0x04ad0, 0x0a4d0, 0x1d0b6, 0x0d250, 0x0d520, 0x0dd45, 0x0b5a0, 0x056d0, 0x055b2, 0x049b0, 0x0a577, 0x0a4b0, 0x0aa50, 0x1b255, 0x06d20, 0x0ada0};//====== 传回农历 y年的总天数 final private static int yearDays(int y) { int i, sum = 348; for (i = 0x8000; i > 0x8; i >>= 1) { if ((lunarInfo[y - 1900] & i) != 0) sum += 1; } return (sum + leapDays(y)); }//====== 传回农历 y年闰月的天数 final private static int leapDays(int y) { if (leapMonth(y) != 0) { if ((lunarInfo[y - 1900] & 0x10000) != 0) return 30; else return 29; } else return 0; }//====== 传回农历 y年闰哪个月 1-12 , 没闰传回 0 final private static int leapMonth(int y) { return (int) (lunarInfo[y - 1900] & 0xf); }//====== 传回农历 y年m月的总天数 final private static int monthDays(int y, int m) { if ((lunarInfo[y - 1900] & (0x10000 >> m)) == 0) return 29; else return 30; }//====== 传回农历 y年的生肖 final public String animalsYear() { final String[] Animals = new String[]{"鼠", "牛", "虎", "兔", "龙", "蛇", "马", "羊", "猴", "鸡", "狗", "猪"}; return Animals[(year - 4) % 12]; }//====== 传入 月日的offset 传回干支, 0=甲子 final private static String cyclicalm(int num) { final String[] Gan = new String[]{"甲", "乙", "丙", "丁", "戊", "己", "庚", "辛", "壬", "癸"}; final String[] Zhi = new String[]{"子", "丑", "寅", "卯", "辰", "巳", "午", "未", "申", "酉", "戌", "亥"}; return (Gan[num % 10] + Zhi[num % 12]); }//====== 传入 offset 传回干支, 0=甲子 final public String cyclical() { int num = year - 1900 + 36; return (cyclicalm(num)); } /** * 传出y年m月d日对应的农历. * yearCyl3:农历年与1864的相差数 ?
