You'll also need a database of course.
Oracle 10g Express will do. It's smaller than 11g by over a gigabyte and will work on home editions of operating systems.

JDeveloper and Oracle SQL Developer don't install that for you, you have to do it yourself.

not declaring them is the ultimate in abstraction, but I'm sure your course material doesn't mean that when it talks about abstract classes and does mention what they actually are.

nope. Bit more modern, but not much :)

that wouldn't work.
The average can only be determined if you know the previous average as well as the number of records over which it was determined.

new_average = ((old average * count) + new_rating) / (count + 1);

do your own homework, thread hijacking kiddo.

As we seen to be heading into history, let's go a bit further back :)

hmm, tricky. Never been much into Italian aircraft of the 1930s and '40s.
It looks like a Fiat G.50, but I'm not 100% sure (mainly the engine cowling seems different, but it could have been produced in several versions with different engines).

<pre> tags are the ONLY thing that will prevent browsers from stripping whitespace.

yup. Tiny bit of mathematics should do.
Addition, division, maybe multiplication, and you're done.

It's an Il-76 (or probably an Il-78, they're externally nearly identical).

thought so.
The for-each structure wasn't introduced until the 1.5 version of the language.
Your compiler is about 6+ years too old.

you didn't use wrong names, just different ones from the ones I chose in the application I pulled that code from :)

It's pretty much boilerplate code, you'll be writing similar methods a LOT.

#28 looks like a Yak-9, but I'm not quite certain.

That's because l_interval does NOT in fact contain a string representation of a date.
It contains a string representation of a mathematical formula which might resolve into a valid date (or not).

You'll need to parse that formula somehow, and the to_date function will be no help whatsoever in doing so.

no, you can't for all the reasons I listed.

NEVER use Java code in JSP.
NEVER try to mix binary and text data in a ServletOutputStream.

though given your attitude to far that eagerness to help has taken quite a steep nosedive...

As you're unskilled any skilltest you take will show your incompetence.
Therefore there's no need to take any, just hand in the paperwork with just your name filled in and go have a drink in the pub.

Actually, they are genderless. And not from Mars.

shh, you weren't supposed to tell that. The female Martian story is the official cover, nicely unbelievable and therefore excellent to make people think there's nothing going on but some people making up stories.

I'll count that as correct. The FA.2 was later renamed FRS.2 before being retired last year.

Let's leave #27 to others indeed.

The Germans indeed knew their lowlevel stuff. Sadly they were also plagued with maintenance problems, resulting in quite a few crashes before the chief of staff did some serious asskicking and reorganised the maintenance training and requirements.

pass the selected value back and set it as the "selected" attribute of the dropdown.

Not only are you abusing JSP for something it's not meant to be used for, but you're also eating exceptions (catching them without doing anything with them).

No wonder you don't get to see errors if you don't log them.

1) always log or otherwise handle any exception you catch
2) never use Java code in JSP
3) never use JSP for anything except displaying results to the client, use servlets instead.

The only truely effective means to prevent software from being pirated is to not distribute it.

Instead run it in the form of a web service, protected by strong credentials and billed per use (either amount of data transmitted or number of calls placed to the application).
Anyone foolish enough to hand out their credentials to others will pay for the use those others make of the application.
If those credentials are further linked to ip addresses or address ranges things get even more secure as the application is now both impossible to crack (not being in the hands of the crackers, ever), as well as the use of it linked to a specific paying account at a specific known location.

what version of the compiler are you using?

Even 2GB on an iPod is sufficient for storing 24 hours of continuous music.
So on a 60GB one you could store a month worth of music, far more than the battery lasts...

So why waste money on the bigger versions, buy the cheapest one you can get and spend the leftover money on accessoiries like a carrying case, better headphones, maybe some external speakers.

Too easy. It's an F-104G, 306 squadron Royal Netherlands Airforce.
It's preserved as a guateguard at New Milligen ("Dutch Mil") military air traffic control station.

says it all, that variable doesn't exist...

not urgent. Come back next year.
Gives you time to learn about code tags, html, Javascript, Java, JSP, etc. etc.

usually you have a list of words and check each word against that list.
There are more advanced systems that do full lexical analysis to also take context into account but you're not ready for those.

look better. The server documentation and tutorials are a good place to start.

even more interesting, in the last post closing the discussion nanosani says he deleted the whole thing :)

there are other tutorials for that, but they're far too advanced for you at this stage.

Or any of the multitude of other free and commercial products that are now available (7 years ago the market was much smaller).

good luck.

it isn't :)

#25 looks like a HAL Tejas.

This should be an easy one, therefore I want the exact subtype as well as correct type of aircraft :)

yup, you finally cracked it :)
The M15 was built to a Soviet requirement. Original requirement was for 3000 aircraft, but after 180 production was halted.

I have an F-15 somewhere that'd have a lot of people confused. It's that experimental one with thrust vectoring nozzles and huge canards :)

most likely there are. If there aren't you'll need to write them, which will almost certainly require the use of extensive JNI.

public void actionPerformed(ActionEvent e) {
                    JFileChooser fileChooser = new JFileChooser(".");
                    int status = fileChooser.showOpenDialog(screen);
                    if (status == JFileChooser.APPROVE_OPTION) {
                        dataFileName.setText(fileChooser.getSelectedFile().
                                             getAbsolutePath());
                    }
                }

Something like this.

nothing wrong with that code, purely going on syntax and grammar...
Of course depending on what you want to achieve there's a lot MISSING from it as it doesn't do much of anything.

nothing, classes aren't synchronised.

if you're really a university student you above all have to use your own judgement and think for yourself.
When presented with a bad example you should have the intelligence to detect that and not follow it blindly.

maybe learn to write correct English and people will be able to help you, kid.
As it is your ramblings are utterly incomprehensible.

No. You can extend only a single class.

well, the error is clear.
There's no array called "splitresult" so you can't access it.

you can't make that work, as Windows will not allow files that are open by another process to be renamed.

Under Unix OSs it might work.

yes, anything to which there are no more references will be deleted by the garbage collector at some point. No need to keep track of that yourself and do things like malloc, calloc, and realloc.

but you shouldn't.
NEVER assume you have sole control over the terminal.

I said it was Italian :)

Congratulations, that's the first one I had to look up ;)
It's a PZL M-15, Polish built cropduster.
