Given the solar calendar (20 120204), how to calculate solar terms (java programming)!

Here is the code, taken from the online calendar.

Import java.text.simpledateformat;

Import java.util.calendar;

Import java.util.date;

Common class test {

long[] sTermInfo = new long[] { 0，2 1208，42467，63836，85337， 1070 14，

128867, 15092 1, 173 149, 19555 1, 2 18072, 240693, 263343, 285989,

308563, 33 1033, 353350, 375494, 397447, 4 192 10, 440795, 462224,

483532, 504758 };

String [] solar $ TERM = new string [] {slight cold, severe cold, beginning of spring, rain, fright, vernal equinox,

Qingming Festival, Grain Rain, Changxia, Xiaoman, Mangzhong, Summer Solstice, Xiaoxia, Daxia, beginning of autumn, Chu Shu, Millennium,

Autumn Equinox, Cold Dew, First Frost, beginning of winter, Light Snow, Heavy Snow, Winter Solstice};

The public static void main(String[] args) throws an exception {

string strDate = " 20 120204 "；

SimpleDateFormat SDF = new SimpleDateFormat(" yyyyMMdd ")；

calendar clendar = calendar . getinstance()；

clendar . settime(SDF . parse(strDate))；

int year = clendar.get(Calendar。 Year);

int month = clendar.get(Calendar。 Month);

int day = clendar.get(Calendar。 Date);

//solar terms

Int tmp 1 = t.sTerm (year, month * 2);

} Otherwise {

The solar terms of System.out.println(strDate+) are: "+solar terms);

System.out.println ("The date of all solar terms is");

for(month = 0； Month & lt 12; Month++) {

}

}

Public int sTerm(int y, int n) throws an exception {

If (y = = 2009 & amp& ampn == 2) {

sTermInfo[n]= 43467；

}

calendar calendar = calendar . getinstance()；

calendar.set( 1900，0，6，2，5)；

date _ 1900 = calendar . gettime()；

long millis =(long)((3 1556925974.7 *(y- 1900)+sTermInfo[n]* 60000)+_ 1900

calendar . settimeinmillis(millis)；

Returns calendar.get(Calendar. Date);
