• Hello!

Hi there, I was told by a friend that i might be able to get some help with some Java work :-) Im pretty new to Java, only started it a few months ago so this may seem simple to some of you but to me its a little over my head still.

Basically its this : For the 3rd part of my coursework i must create a program that:

(The School of MIS maintain the total percentage marks of 30 MSc students in a computer-based system. For each student they store the following information in the system:
A unique number between 1 and 30 that is often used to identify the student.
The overall percentage mark obtained by the student
The student’s names. Implement a single class called MScResults that contains a number of attributes and methods. The methods include:
setNames(), - This public method takes two parameters. The first parameter is an integer and the second parameter is a string
storeMark(), - a public method that stores the total percentage mark achieved by a given student. It takes two parameters. The first parameter is an integer and the second parameter is a number that can have fractional parts
getMark(), - public method that returns the total percentage mark obtained by a given student. It takes a single numeric parameter
getNoOfStudents(), - public method that takes two parameters and returns the number of students that had total percentage marks between the given two numbers
displaylowestMark(), displayhighest() and
displayResults() - This method displays the results of all the students in the format shown below.

Student Name Percentage Mark Staus/GRADE
James Clever 80 Distinction
Java Shy 33 Fail
.. ..

The “Status/Grade” of a student is determined as follows:
If the total mark is 69.5 and above then the “Status/Grade” is “Distinction”.
If the mark is between 59.5 and 69.4 then the “Status/Grade” is “Merit”.

(b) Implement a Test class for the MScResults class above.

Ok, that isnt just spam. What im stuck on, basically i wont lie - most of it. But espcially the Unique number thing, how can i make an array to check the number isnt in use allready ? is that possible ? 2, The displayResults() - I have no idea how to do this at all, not in the way displayed, 3 - A test class shouldnt be that hard to make but im not sure

Sorry for the spam. I would really appreciate any help at all, Im just pretty new to Java. If your bored and want something to do - by all means help yourself :-) Post a reply here if u can help in anyway or please e-mail me b_beta@btinternet.com

Thanks,

Michael Merola

i'm by no means a java guru, but consider thsi some starting advice.

create two classes: MScResults which contains the methods and a Vector(), and then MScResult which represents a single result. give the MScResult class three properties - id, name and score, and a single method, getStatus().

i might right the actual java a bit later because i'm bored

write?

left.

jesus. i am fick

ok, an attempt at the class and some basic tests are posted here:
code.iamcal.com/java/

cal - remember that next time you shout at me for being fucking stupid :P

Get it right, Chay. He'll shout at me first then I'll cry and remind him it was you that being stupid and then he'll call us both fucking stupid.

*double post grumble grumble*

lol cheers, ignore them :-P

Thanks for the help, im still working on that key id thing + now incorporating what you have done into my own work. Thanks for that, if u get bored by all means help yourself to more of the pie ;-)

"i'm by no means a java guru, but consider thsi some starting advice. "

Holy FUCK. We've found something Cal doesn't rock at. 0_o

I appologise to cal now for bringing it up ! !

hmm for some reason, i cant actually get the program to work cal, maybe something im doing wrong ?

well, it compiles fine for me. what happens when you run comp.bat to compile it?

I was able to get it to run, but only after changing one line.

Line 23 of MScResults.java

Before:




After:

aha :)

(you have a older version of the JDK)

ya probably. I won't even tell you what I used. I would be the laughing stock if I did.

Some of these things are knd of neat to watch.

Sodaplay

I hate JAVA. It's too complicated for me. It was originaly created to sunc household appliances

I prefer Bali.

whats that?

hehe

Altogether now...

*whoooooosssh*

what????

isn't it?

Hmmm?

Small boys in the park?

Jumpers for goalposts?

Hmmm?

Stop confusing me!!!!!!

I bet breathing confuses you, son...

"in....out.....in.......in......in again...*gasp!*"

*thud*

Now Now Brock, be nice.

And destroy my reputation?

Bollocks.

im stressed!!!!! ive got my SATs in... urr.. 2400 - 1759 + 900 = 1541 ... 15 hours and 41 minutes... BRAIN OVERLOAD!!! SYSTEM SHUTDOWN¬~¬~¬~¬ 5 4 3 2 1 *FAINTS*

+ i fucked that calculation up!!

What are the chances, eh?

Somebody kill me!!!

If only you knew the risk you were taking, saying that to me...

I can take a really wild guess...

I think merolam should get off his arse and learn how to program himself and not get other people to do his coursework for him :/

I think you've got a point, Sal.

Cal, that's it. No more help. From now on you code your own site. Sorry but you have to learn.

Hehe who helps him? Or had you better publish it in a web page?

:)

Well he was told by a friend. Perhaps we should help him. I mean its 2 months right?

i didnt mean to force anyone ! i just got stuck, trying to figure it out myself just donno how to , lol :-/ need a way to enter the values get_xxx etc, cheers for the help so far. To all.
