Question

I have a vector that is created by retrieving data from a database
It is filled with information that includes Date, Time, Volume ect…
I need to create a spreadsheet from these values however I need to Remove values where
the date is on a weekend(and specific holidays if possible) but more importantly the weekends
If anyone knows of a function that is able to do this that would be great Thanks.

If you have a Date object in Java, then you can use the Calendar object to do this.

Get an instance of the Calendar, then call get(Calendar.DAY_OF_WEEK). If the value is Saturday or Sunday, remove it from your Collection.

Calendar calendar = Calendar.getInstance();
calendar.setTime(yourDateObject);
int dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK);
if(dayOfWeek == Calendar.SATURDAY || dayOfWeek == Calendar.SUNDAY) {
    //remove this Date
}
