Days in a month

[RedSon]

Also I see another problem here

 
isLeapYear = consolein.nextBoolean();
 
				if (isLeapYear) {
					intdays = 29;
				}  else {
					intdays = 28;
				}

There is no test going how if some type in feb what will happen.

Didn't you just post this?

EDIT: Nomad keeps editing his posts so now this one doesn't make any sense. Disregard it.

I agree with dmjpro (see reply#2): why not instantiate a GregorianCalend ar
given any day in a month and a given year. The getActualMaximu m() gives
you the number of days in that month in that year.

Jos you silly, silly boy. Using a GregorianCalend ar would be too easy. Besides what if he wants to eventually accept input from the user in sidereal time?

Yes kids, its called sarcasm.

Sorry about that one RedSon.
I read and I saw a mistake... and I wanted to correct it. You're to fast on the draw today.

Huh, my wife complains about that too.

Okay no more hijacking threads after this one.

There are quite a few problems with this but what chiefly catches my eye is:
[CODE=java]
System.out.prin tln ("The number of days in" + intmonth + "/" + intyear +" is:");[/CODE]

Do you see anything wrong with this?

is it too many +'s or the fact that I'm using intmonth? intyear? should it just be 'month' 'year'?

[RedSon]

its not about intmonth or intyear, although those are probably poor choices for variable names. It has to do with what comes after the ":".

You just want to print out the amount of days in a giving month right!!!!
SOooo!!!

ahh crap..duhhhh. I am really dumb with this stuff.
I'm a complete novice and I think I make a bigger deal than I should out of this.

ok, here is what I have so far. When I run the program, it asks you to enter the year and the month, and after that, nothing happens. What am I missing here in order to figure out the days? I can't think of what to do..

case 2:
//Check for leap year

System.out.prin tln ("Checking for leap year (true/false)");
isLeapYear = consolein.nextB oolean();

isLeapYear =
((intyear % 4 == 0 && intyear % 100 != 0) || (intyear % 400 == 0));


if (isLeapYear) {
intdays = 29;
} else {
intdays = 28; }


//Display results
System.out.prin tln ("The number of days in" + intmonth + "/" + intyear +" is:" + intdays + "");
System.out.prin t ("Thank you. Run Completed");



}

}

Erm, <raises hand/>, hint: it starts with a capital G and ends with "regorianCalend ar".

kind regards,

i think you should double check the position of your brackets

and you need to use code tags or i'm going to start getting cranky!

[emekadavid]

You were doing just fine until switch had to check for leap year. You seem nervous there. in life as well as in coding java, remember, KISS. Why did you have to check for nextBoolean when the user doesn’t know if it’s a leap year or not? Doesn’t make sense. That’s the work of your program. Take away consolein.nextB oolean from the logic of your code. After that line, you need to realize that you’re checking intyear (according to convention it should be intYear, pls!) for leap year where switch evaluates to 2. get it. So, what if we want to check for leap year? Keeping it simple, I’ve prepared something based on the principles below.

public class Checker {
	public static void main(String[] args) {
		int intyear = 1996;  //assuming this is what the user entered.
		int intdays;  //you have this already from the user
		
		//the below if from your logic for checking leap years. don't have
		//the time to consult the wikipedia. 
		<Line removed to comply with homework posting guidelines>
		
		System.out.println("The number of days if february is chosen for "+
				intyear+" is "+intdays);
	}
}
//this code is based on principle i.e where your switch evaluates to 2.

now your leap year is resolved I believe.
