Here's a bit to get you started.

SavingsAccount should extend Account
CheckingAccount should extend Account
SpecialCheckingAccount should extent CheckingAccount

implement Account first, then...

Out of curiosity, what's the advantage to the people who sign up? I get why marketers/advertisers would sign up. But why would users? I mean, most people I know don't want to be marketed to.

Not...

There's got to be some good libraries/tools out there that do the charting part of this. Then all you'd need to do is parse the text file and pull out the information you want to chart, and feed it...

Hey all!

Please check out my new site. It's been live for a couple of months now. I read music reviews for all the new albums and summarize the reviews Yes, it's quite a glamorous life, haha. ...

It's been a while since I used java random number generator, so hopefully someone will correct me if I'm wrong, but I believe if you use the same seed for the Random number generator you'll get the...

Are you using stacks to keep track of how deep into a compound expression your in?

Post up some code and I'll take a look...

Null pointer exceptions are unchecked (the documentation will never say that a method can throw it). So it could be thrown from one of the methods you call.

Can you add ex.printStackTrace() to...

Kermit, here's a bit to get you started. First there are two kinds of operators unary and binary. Unary just means it effects a single expression and binary means it works on two.

So ¬ is unary...

What problems are you running into? It sounds to me like some kind of recursion is the way to go. What's not working?

Hi, sorry for the delay in responding...

And actually sorry, but I don't know how to help. The fact that you can run cat and grep really is weird. The only thing I can think of is running find...

Sounds like you need a web crawler. There are probably a lot out there that fit your needs. I'd look into one of those to find the URLs you need to count keywords in. You should look into the...

can you post the exact error message you're getting from cygwin?

Are you familiar with recursion? It would probably simplify things for you. And it's a good thing to learn about.

But, for what you have now, your running into trouble because the "level"...

Regular Expressions are a great tool, but probably overkill in this case. You can iterate character by character and use methods in the Character class to see if the current character is a letter,...

Whoops, I didn't see your post, before I posted mine. Looks like you got it right.

is your classpath set correctly?

Did you look at page 4? From the article:
The incorrect assumption here is that the exec() method acts like a shell interpreter; it does not. Instead, exec() executes a single executable (a program...

That runtime.exec stuff is a real pain to use with a lot of traps. Here's a great article that's helped me out a lot:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html

It's a long...

Does it have to be recursive?

Since it works on smaller polygons it sounds like the function is getting called too many times and you're running out of heap space.

Depending on your needs the...

Assuming you only allow a single selection in the JTree you can use: JTree.getSelectionPath.

It returns a TreePath which basically holds a list of the hierarchy that is selected. Then you can...

Yeah, it's a little hard to tell without seeing more, but I like talking out of my ass so...

Saying the "upper bound" is just a fancy way of saying "how many lines of code". But in a more general...

Also, it's probably more important that the underlying mysql servers are the same version than the phpadmin version. But yeah, what priteas said.

I personally use linux, because that's what's hosting my site, but it's certainly not mandatory. It may make some things easier, but probably not :)

I think the main thing to remember is that...

You should look into the WindowAdapter class. It has a windowClosed method that you can override to keep track of when a window is closing.

You'll need to subclass WindowApater and then add...

in showAllSeats, I'd change
fn == "1294"
to
fn.equals ("1294")

the double equals checks for object equality (i.e. the same object in memory)
.equals() checks to see if it's the same string

Yeah, I agree with you that a lot of search implementations tend to be too literal.

Lucene is very nice in that respect. If you have a domain specific site, you can plug in your own aliases for...

Very nice! One small comment is that I'd make the main part of the home page fixed width. When viewed on a widescreen monitor, the stop/play/pause control and the concerts and albums box moves...

I like it! You've got the most important thing right up front -- the photos turned into paintings/drawings/etc. Nice testimonials and how it works. Very clear and inviting.

One nitpick, the...

I think you could also do more on the home page to welcome new people and set expectations about what the site is going to do for them.

Good luck!

I've been developing a custom search for my site using lucene. I've found lucene fast and very flexible. I have a small site so the flexibility is more important to me than the speed.

I messed...

The screenshot shows prefuse.demos.TreeMap.jar

Maybe that's causing the problem...

I have to admit I'm not familiar with prefuse. But when I run jars from the command line I use >java -jar <jar name>

Scanner implements the Iterator interface. So you have to use next() to go to the next element somewhere inside your while loops.

In other words the scanner is checking to see if there are more...

It may not help with page rank and stuff like that, but they can be useful by sending traffic your way from people who browse the directories. But I agree with earlier posters that it's not so...
