Hi java/ c++ geeks out there,
I need some help on below problem (can use java or c++):

Finish the returnTotalDays method in the CalDate class given below.
returnTotalDays returns one of the following.

I.  the number of days in the given month if (year>0 and month>=1 and month<=12);
II.  the number of days in the given year if year>0 and month is 0; or
III. -1 if year<=0 or the month is not in the range of 0..12

public class CalDate {
public static int returnTotalDays(int year, int month) {
…
}
}

Thank you for your help!!

import java.util.Calendar;
class CalDate {
    public static int returnTotalDays(int year, int month) {
        if(year < 0 || (month < 0 || month > 11)){
            return -1;
        }
        else
        {
           Calendar c1 = Calendar.getInstance();
           /* remember 0 in the month field always represents january
            */
           c1.set(year, month, 3);
 
           if(month > 0){
               return c1.getActualMaximum(Calendar.DAY_OF_MONTH);
           }
           else {
               return c1.getActualMaximum(Calendar.DAY_OF_YEAR);
           }
        }
    }
 
    // method main(): ALWAYS the APPLICATION entry point
    public static void main (String[] args) {
       //System.out.println ("Hello World!");
       System.out.println (returnTotalDays(2004, 0));
 
    }
}
