Answer 1

public static int getDayCount(String dateTime) {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM");

Calendar calendar = new GregorianCalendar();
try {

calendar.setTime(sdf.parse(dateTime));
} catch (ParseException e) {

e.printStackTrace();
}

int day = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);
return day;
}
public static void main(String[] args) throws ParseException {
String mouth = "2015-02";
int day = getDayCount(mouth);
for(int i =1;i<day+1;i++){
System.out.println(mouth+"-"+i);
