Below are the UI requirements for my assingment

It must be composed exclusively with components from the Java Foundation Classes (Swing components).
It must allow the user to search the data for all records, or for records where the name and/or location fields exactly match values specified by the user.
It must present search results in a JTable.
It must allow the user to book a selected record, updating the database file accordingly.

My question is :
Do i provide the UI with create and delete functions; because this methods are in the DB interface.

Hi David,

You should follow the must condition in your requirement. According to your requirement, you should provide the functionality in your UI for booking the record. After booking, the corresponding record should be updated in db. You can implement other functionalities in UI but they are not mandatory and also you will not get extra points

I have used RAF for reading the db schema. Btb, my assignment is B&S.

all the best

No, partner.

Hey guys,

Thanks for the reply, since my UI doesn't need a create and delete functionality. I am thinking of throwing an UnsupportedOperationException i.e in my Data class that implements the DB interface

example code

 void create(){
throw new UnsupportedOperationException("message");
}

[Roberto Perillo]

What if other GUIs (other than yours) do support these operations and use your implementation of the Data class?

[Alenkhe David]

this is the customer id specification:
Note that for this application, you should assume that customers and CSRs know their customer ids. The system you are writing does not interact with these numbers, rather it simply records them. If this field is all blanks, the record is available for sale.


All the fields in my db file all have thier customer id blank which means its available for sale(booking).

UI specs says :
It must allow the user to book a selected record, updating the database file accordingly.

question is:
do i allow the UI to update the customer id field? because there is no way to book a record with out a customer id.

Yes, partner. You have to provide a way for the user to update the record's customer id field, but this is the only field that needs to be updated in the record.

Okay thanks partner.

My spec says something; they take bookings only within 48 hours of the start of room occupancy.

I am going to implement this; below is a test for comparing dates.

class TestDate {
 
        public static void main(String[] args) {
                Calendar cal = new GregorianCalendar(2005, 07, 22);
                Calendar cal1 = new GregorianCalendar(2005, 07, 25);
                Date avaiableDate = cal.getTime();
                Date bookDate = cal1.getTime();
                System.out.println("Today :" + avaiableDate);
                System.out.println("Book Date :" + bookDate);
                // Get difference in milliseconds
                long diffMillis = cal1.getTimeInMillis() - cal.getTimeInMillis();
                // Get difference in hours
                long diffHours = diffMillis / (60 * 60 * 1000);
                System.out.println(diffHours);
                if (diffHours<0||diffHours > 48) {
                    //    throw exception
                        throw new Exception("Date Occupancy Exception");
                }
                //can book record
        }
}

did you implement the 48hour rule in your code? i am thinking of roling out my own exception i.e dateoccupancy exception .

Send me your thoughts Thanks.

There are many who did not implement the 48-hour.
I implemented in my case, but it was a really simple implementation.
I suggest you document carefully this choice, whatever it is.
