Library information system

[iffa n wanie]

Develop a library information system that provides the following functionalities:

a) Add New Patron
b) Search Patron
c) Check Out Book

The patron ID is unique and is generated automatically by the system. Any patron can borrow at most three (3) books. The period of loan is two (2) weeks. Your program will retrieve the computer’s current date to be used as the date a book is borrowed and calculate the due date automatically. You can make the assumption that the library has only one copy of any book title. At least five (5) patrons’ data should be used to demonstrate the working of the system.

We don't do students' homework here.
If you've written some code and are stuck with it then you can post it we'll be willing to help.

yes..we r stuck here.. we r newbie n need some help n guidelines

[r035198x]

yes..we r stuck here.. we r newbie n need some help n guidelines

What have you done so far?

P.S Do not use SMS language here.

we just ask for an idea..not the answer..your kindness is very appreciatable..

First list down all the objects that are in your system and their properties.
This will tell you what classes you need and the fields and methods to put in them.

List also the relationships (if any) between your objects.

You can even turn it into a bit of weird fun: play the CRC game, the acronym
means: Classes Responsibility Cooperation. Each person represents a class.
There's a librarian who hands out books and takes them back again. There's
a boring administrator who registers new patrons and there's a patron who
wants to return books or pick them up from the library.

There are a few usecases to play through:

1) register a new patron
2) register an already registered patron
3) a patron picks up a book at the librarian
4) a patron picks up a non-existing book at the librarian
5) a patron returns a book
6) a patron returns a book s/he didn't pick up

etc. etc.

Try to 'play' all these scenes and figure out who does what and what is needed
to complete the task. Jot down all the outcomes and you've already completed
all your pseudo code for your entire system.

kind regards,

Jos (<--- returning a purple poodle dog puppy at the administrator ;-)

... and bear in mind that patrons can be banned for making fun of the administrator (or for breaking any other such rules).

If an administrator mistakes a purple poodle dog puppy for a book s/he doesn't
deserve anything better :-P

Depends on the how iffa and wanie set up their system. I'd love to hear their thoughts on this but I'm afraid it seems we've been deserted again.

Yep, my thoughts exactly; when it comes to a bit or reading or thinking then:
*voooooom* they're out; we are supposed to spoonfeed well written, well
documented 'the jav codez' I'm afraid ;-)

actually we are freshie just learning java only one month..we not used to write the coding yet..however we are tried and stuck till here:

could someone help us with the coding..
thank you

[JosAH]

actually we are freshie just learning java only one month..we not used to write the coding yet..however we are tried and stuck till here:

< wallpaper removed/ >

Please don't dump quite a bit of code here and just tell us that "you're stuck".
Why don't you tell us what the problem is? i.e. what doesn't do what you expected
it to do? Does it compile? Doesn't it compile? What did the compiler whine at you?
Does it run or not? Was there an error diagnostic message? If so, what was it?
If there wasn't but it didn't do what you'd expected, tell us about it. Help us to
help you but please don't dump your code and expect us to solve 'it' automagically.

kind regards,

Jos

ps. @r035198x: see? I wrote 'automagically' again! ;-)

[r035198x]

1.) All code posted here should be posted wrapped in code tags.
2.) Don't start writing the code until you've got all the objects and actions on paper first. That will only lead to lots of frustration.
3.) All that code IMO, is a mess. You may need to spend time on a Java tutorial first before writing the code. You can find some tutorial links here.
4.) Do you think patrons should make fun of an admin who can't tell the difference between a purple poodle dog puppy and a book?
5.) Never use the word automajically. It does not exist.

1)

Tango Zulu Bravo Roger, over Roger Whiskey Roger and out Roger Roger Roger;
 

2) Erm, I'm sure you mean that the other way around in some twisted way? Sort of?

3) r035198x is such a lovely person, but he's often right and supplies the proper
links as well ;-)

4) yes.

5) .s/j/g/ and poof: it exists!

kind regards,

Jos ;-)
