java.util.Calendar and the before method
Came across this nice problem today:
The java.util.Calendar
class provides a method "before(Object)
" which is supposed to tell you if the calendar calling that method is before the given object. BUT, as stated in the javadocs [http://java.sun.com/javase/6/docs/api/java/util/Calendar.html#before(java.lang.Object)] it only works if the passed object is a calendar itself. If its a java.util.Date
object, then forget it, the method just returns false, even though you would expect the calendar to be able to compare its date with a Date
object.
I can't quite figure out how come they don't just require a Calendar instead of an object. There is nothing in the code to give the reason. So, I just don't get it. But it's been like that for three years now, so I guess we just need to get used to it :-(
