I need to compute several dates based on another date. I understand how to use the GregorianCalendar to add weeks to another GregorianCalendar object, but I have a date. Is it really necessary to get each portion of my date in order to instantiate the GregorianCalendar object? I don't see where the constructor takes a date. Any suggestions? |
Ajay, That was very helpful, but sometimes the best way to teach is to point the student in the right direction and let him find the solution on his own. If Param had to code it himself, he would end up much more familiar with the methods of the Calendar class and how to use them. Scott |

So this code should be rewritten not to mention GregorianCalendar. Of course, depending on you locale, the object returned by getInstance could be an instance of GregorianCalendar, but then again, it could be an instance of the Thai Buddhist calendar, ... |
