Date problem

Hi, just got a question. I'm creating a program which is basically calculating quote for a carpet laying business. Basically, the person has a choice of vinyl and timber (this is user input). If a person chooses vinyl, then the installation cost is 2 business days after the quote (the quote is generated from the system date. so if i ran the program completely compiled today, then today is my quote), and if the choice is timber, then the installation for that is 2 weeks. So basically my program needs to determine which floor type the user wants, and if the quote is generated today (21/3/06) and its vinyl, my program must output “the installation date is on the 23/6/06). And yes, if the choice is timber, then it’ll just output the date from 2 weeks from now exactly. The timber side of things, I have completed fine, but I’m having a problem with the vinyl. Of course, if my quote is generated on Thursday, then the installation laying date should be (on the monday of the following day….as you can imagine, if its done on a Thursday, then it’ll Friday, Saturday, Sunday, Monday …of course, you do not count Saturday and Sunday as business days). So far my code is as follows.

JAVA Code:

static final SimpleDateFormat sdf = new SimpleDateFormat( "dd-MMM-yy" );
static final SimpleDateFormat blob = new SimpleDateFormat( "EEEE" );

(then in main I have this)

JAVA Code:

String dateString = sdf.format( new Date() );

if (FloorCover == 1)
cal.add(Calendar.DATE, 7);
else if (FloorCover == 2)
{

}
// FloorCover is basically just an integer value. So if user wants timber, then FloorCover is just 1, and if user wants vinyl, then FloorCover is

2.

Of course, you can see my if statement for timber is done (and working), just not sure how to go about doing the vinyl part. Cheers

Just incase you need this, i have these packages.

JAVA Code:

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.*;

First, you say in the beginning that timber is 2 weeks, but you only add 7 days?

JAVA Code:

cal.add(Calendar.DATE, 7); // 7, not 14 ??

Then for the other part, why not just add the 2 days, and then check the day of the new date? If the new date happens to be Saturday, add two more days, if Sunday add one more day:

JAVA Code:

else if (FloorCover == 2)
{
    cal.add(Calendar.DATE, FloorCover);
    
    int dayOfWeek = cal.get( cal.DAY_OF_WEEK );
    
    if ( dayOfWeek == Calendar.SATURDAY ) 
    {
         cal.add( Calendar.DATE, 2 ); // bump two more days to Monday.
    }
    else if ( dayOfWeek == Calendar.SUNDAY ) 
    {
         cal.add( Calendar.DATE, 1 ); // bump one more day to Monday.
    }
}
