pointing to previous working day using java
<p>I am new with using java.calendar.api.
 I want to point to the previous working day for a given day using java.
 BUT the conditions goes on increasing when i am using calendar.api to manipulate dates 
 since I had to consider the usual weekends and the pointing to the previous month and also i had to consider the regional holidays in my region......</p>

<p>for ex:say i had to consider the U.S holidays and point to the day before that.</p>

<p>Is there any way i can <strong>define my own calendar</strong> and use it so that date manipulation senses all those usual changes?</p>
