I've heard of JAVA Beans, but not JAVA Baby! But now, Mary can have another Mod in Java! Tonight is my first Java class also. Got to keep up with you kids!

One of the unis my son may go to has JAVA as the fundamental language of choice so I may take it up (time permitting) if he goes there.
Prolly not for a year or two though ;)

Good luck anyway Dököll :)

Remember; for those late night classes, nothing keeps you up and attentive like JAVA. Or Tea.

It's too bad almost nobody knows about Objective C anymore (except for those
Apple folks). Objective C stole^H^H^H^H^Hborrowed a lot from SmallTalk and
Apple (NextStep/OpenStep) added quite a large library to Objective C.

If you've worked with that library you can see that Java isn't a very original work.
Java's core classes stole^H^H^H^H^H borrowed a lot from NextStep/OpenStep.

And they deleted a very important fun feature from the language: runtime type
checking. Sun must've judged it a too dangerous feature ... Introspection just
doesn't make it compared to Objective C's rttc.

kind regards,

Jos

wishing you luck then:-)

my professor's a monster, she says she'll have no mercy, I think that about sums the fact I'll need to truly stay awake for this one.

Much appreciated...

When the time comes, good luck with it:-)

My wife juiced me up today, with tea though, berries and so on...As weird as it sounds, I think I need a better chair, a chair truly uncomfortable though:-) And that's the weird part, I fall asleep in my current one, too comfortable, I need steel, I think, cold...

...weird...but I think that might help keep me awake. Which is very important because I am certain I'll have my nose in it late, cannot do much here in the afternoon.

So yeah! I am prepared, also an oversized mug should do the trick:-)

My prof seems better than I expected. She did a really good job and is very organized. I just need to sit next to the projector screen: I couldn't see a thing from across the room. What book are you using? Mine is Shelly, Chashman's Java Programming (Comprehensive). Good luck! --Sam

Shelly makes good books, mine's David J. Barnes and Michael Kölling, interesting last name:-) Book's name is Objects First with Java, it's an introduction to it so you may have a stronger version. I do sit right out front, I like to listen and take notes at the same time...thanks Sam!

Have a great week-end...

You should look into Big Java. It's the book I learned Java on, and it's awesome.

>you may have a stronger version
It's for two terms

>Big Java
I was hoping for Little Java! BTW, Ganon, we can post our homework on the Java board and you'll do it, right?

The experts on this site are more than happy to help you with your problems but they cannot do your assignment/program for you. Attempt the assignment/program yourself first and post questions regarding any difficulties you have or about a particular function of the code that you don't know how to achieve.

Please read the Posting Guidelines and particularly the Coursework Posting Guidelines.

Then when you are ready post a new question in this thread.

You guys are lucky... I had to learn Java from a book written in Icelandic!... By my teacher!!

No wonder I can't remember a word of it :P

Ignoring Gannon, like the rest of our posters:o)>>

So, the course was called Kaffi?

Quote: Originally Posted by SammyB Ignoring Gannon, like the rest of our posters:o)>> So, the course was called Kaffi?

lol no. It was called "Tölvuforritun fyrir byrjendur" or something like that... (A cookie for the first one to translate that! :)

No, sadly there was no coffie :(

I think I like your professor. InterTran gives it as "Computer program pay lip service to introductory." Which I guess means "Computer Programming for Smarties"

Ok that's hilarious! :D
"fyrir" means "for"... how on earth do they manage to translate that to 'pay lip service'? :)

Well, listen to this, even with the use of a certain software, specific to the book itself, I still manage to not understand, or be able to skillfully modify the code given...

I am in up to my wrist, thus far...

What software are they having you use?

Quote: Originally Posted by Ganon11 What software are they having you use?

We're using a software by BlueJ, can be seen at BlueJ.com.

Ganon11, Sam, Lab 3 was still terrifying, I requested help and still did not get it. Thing is when the professor stood right by me an exaplained what I was doing wrong, I tried again and succeeded, the moment I jumped to something else an attempted to try on my own, no way, not gonna happen:-)

BlueJ allowed me to modify code already wirtten, which did at one point give me a sense I had an unfair advantage, until Lab 3:-)

I think what must happen though, and I will post to our wonderful Java forum, is my creative juices must start flowing, light buld must come on, it did in VB...

Hope to see you in the forum, I have a feeling talking/writing about it also helps.

I found a copy of Java for dummies, keeping it close. Will also give Big Java a try, need all teh help I can get, it seems:-)

My advice, of course easier given to others than myself:-) I think Java having an object oriented style also should make it not so much of an animal...

Arrgghh! Oh no! Run away! Run away!

Not another n00b...If you ask us about Rational numbers, or an Inventory, so help us...

XD

Man, I'm thankful: we're still doing "Hello, World" splash screens! But, in this next chapter we deal with the "The Body Mass Index Counter!" Definitely a step up from "Hello, World!" Swing Components, Labels, and (dangerous) math! Ohh, Ahh!

Just be scientific and mathematical and impress the rest of the class: multiply
everything by Math.PI.

My lab partner tonight said, I like you and all but, I'm out of here...You tell me how you made out, grinning...

I dont' think I'll ever see her again:-)

Second time taking it...

Should you be worried?
Do you have that effect generally with girls?
(:D)

Quote: Originally Posted by NeoPa Should you be worried? Do you have that effect generally with girls? (:D)

Well I did also need a shower that night:-)

I complainned t my colleague at work today, poor woman. Stayed up late last night venturing about each sequence of the code; of course you know this means to no avail.

But I have a feeling that special light bulb will in fact come on...
At it again 2 nite:-)

It's almost like preparing to go in the dungeon, truly amazing...

Here is what kept me up last night:

"Class or interface expected error"

A right curly brace too many in the middle of the code; keep that one in mind.
The line number from the error diagnostic is the give away.

Jos

Here's one that's not a give-away. I thought that it was going to keep me up all night, but it all of the sudden just went away. The error message was "C:\Documents and Settings\Sam\My Documents\CSD224\Homework\Chapter3\Assignments\Kil owattApplet.java:12: KilowattApplet is not abstract and does not override abstract method actionPerformed(java.awt.event.ActionEvent) in java.awt.event.ActionListener
public class KilowattApplet extends Applet implements ActionListener"

Code was


The funny thing was that someone else in class had the same error and it took us as a class at least 30 minutes to find the mistake!

I've seen that error diagnostic more than often and always I had misspelled the
method name 'actionPerformed'. I always tend to spell it with a leading capital A.
Dunno why; my fingers seem to like that ;-)

Jos

I always forgot the first r and wrote it as actionPeformed

Quote: Originally Posted by r035198x I always forgot the first r and wrote it as actionPeformed

The one I hate most is the PropertyChangeListener with its propertChange method;
it is called when the bound property has changed and I alway type those
darn things as 'PropertyChangedListener' or 'propertyChanged' with a parameter
type of 'PropertyChangedEvent'. I don't even check anymore: when I see the
compiler whining again about classes not being declared abstract and yaddayadda,
I simply remove the 'd' from the methods and inner classes ...

kind regards,

Jos

I guess that I should have realized that you-all would see it at once. It's one of those error messages that is so cryptic that you remember it. The funny thing was that I had no clue, but I had made some mistakes, so I retyped the code at the end and of course I was mystified as to why the message went away.

It's one of the compiler messages that are not tied to a specific line where some
syntax mistake should be. There is no syntactic mistake in that code; it was
just the fact that you stated that your class implements the ActionListener interface
which it effectively doesn't because there is no 'actionPerformed' method defined;
the class isn't defined to be abstract either so all the compiler can tell you is what
I just wrote. It is a semantic mistake which the compiler checks for you.

Jos

That sounds very familiar...just got word through Java forum on this:-)

Will keep this and any othe
