IF statement problem

I need an if statement that determines the number of days in the month entered by the user.
Also a switch statement would be fine...right?

Either an IF or a SWITCH would work, but you'd have to check for whether it is a leap year when doing February. Alternately you can use the "java.util.Calendar" class, calling the "getActualMaximum(...)" method with the correct field. You'd create the calendar, set the year and the month, and then call the "getActualMaximum(...)" method.
An IF would look something like (assuming the month is an integer where January==1; if not, adjust code accordingly):

You could also set up a static int array that contains the days in each month, and then use the month number as the array index. Again, you'll have to adjust for leap year.
So you have lots of choices ...
 
It is sorta covered in the JavaRanch Style Guide.
