Java judges the start time and end time.

Java . text . simple date format SDF = new Java . text . simple date format(" yyyy-MM ")；

Java . util . calendar star calendar = Java . util . calendar . getinstance()；

Java . util . calendar end calendar = Java . util . calendar . getinstance()；

string starStr = " 20 1 1- 1 1 "；

string endStr = " 20 12-02 "；

Java . util . date star date = SDF . parse(starStr)；

Java . util . date end date = SDF . parse(endStr)；

star calendar . settime(star date)；

EndCalendar.setTime (end date);

int instance = end calendar . compare to(star calendar)；

while(end calendar . compare to(star calendar)& gt； =0){

system . out . println(SDF . format(star calendar . gettime()))；

//? I output here, you can handle it yourself, lists and so on.

StarCalendar.add (calendar. Month,1);

}

}catch(ParseException e){

e . printstacktrace()；

}
