Is there a way to add methods to GregorianCalendar in Java?

Question

I'd like to make a method called "isBetween" returning a boolean, seeing if a GregorianCalendar date falls between two others. Alternatively, I'd like to just define operators of < and > for the class. I'm pretty new to Java, so I'm not sure....can I even do either of those? If so, how?

Answer 1

Java does not support monkeypatching or operator overloading, but feel free to subclass GregorianCalendar and add whatever methods you need.

But then, do you really need a new method to do cal.after(startCal) && cal.before(endCal) ?
