And I'm kind of nervous about it. I'm fairly decent in coding but I'm still very unsure about the whole thing, since this is my first AP as well.

Anyone else took an AP exam or better, AP Computer Science A (Java), any tips? pointers?

I love computer science humor! LOL, you probably don't get the connection yet, but you will if you decide to be a CS major.

I've taken Java exams in college; nothing too difficult, really. You'll probably breeze through it if you grasp the concepts.

I want to major CS in college, any advice or thoughts on it? What kind of jobs can I get other than programmer?

I worked on CS only as a minor for fun more or less, it isn't the field I chose as my career. It was just something that I enjoyed doing so I can't really be of much help.

I have my AP US history exam in a week. It should be a cakewalk like AP Human Geography was last year. Next year with AP Chemistry, AP European History, AP Language and Composition, and AP Psych/Bio/Stats (as this one isn't set yet) I'm kind of scared.

I didn't even know there was an AP Computer Science course though. My school doesn't offer that.

I'm not in an AP class but I am a Java programmer. Java itself is easy but understanding object oriented programming is the real difficulty.

You'll want to brush up on constructors and objects. Don't worry about the petty stuff...

A four year CS major does some programming but can move into more high level designing and managment. Programmers are a dime a dozen but a guy who can design software well is much more difficult to find and they make much more money.

Eclipse is great. When I was taking my Java classes, we played around a lot with different IDEs. I eventually starting taking preference to a program called...oh shoot, the name has slipped my mind now...JPad, I think; it could do Java, PHP, Javascript, HTML, JSP, and some other things as well.

How is AP Chem? I've heard it's difficult, but I normally have no problem with remembering things or math. I'm taking it next year as a Junior, but I kinda want to know what to expect.

Well lemme see, inherited objects do not containthe constructors of theirparent class, I mean its not hard, but yeah the concept is the hard part (making code in about 30 min wtf)

I took it last year and got a 5. It's really easy as long as you have the basics of java down, and a practice test or two wouldn't hurt either. Just make sure you're familiar with Gridworld.

I've got AP Art History this year, and heard it's a huge pain :( I'm shooting for a 4. Don't want to hijack this thread but does anyone have any experience with it?

I think I got the basics, any way to test that? Its just the multiple choice, those things are so tricky and so deceptive also, my gridworld Broke when we were doing it, so I don't know anything past Z-Bug, and isn't gridworld just modifying some code with the Extends operation?

I have a Java exam for Computer Science in a few weeks. Should be pretty easy as it was only an intro unit and we've done basically nothing yet in terms of programming. Just classes and their fields, constructors and methods, and also relationships between classes and other basic stuff.

It's not bad at all, but I've got the mind for it. Most others in my ****have pretty poor grades. With what you've told me, you should do fine.

Anyone can understand that joke Does anyone go nuts when they see { on the same line as anything else? I know I do while(stuff) { } thats how it should be :P I found Object Orient stuff to be easy to understand. But I get it why some might not. If I was a Java teacher I would make people do things without it at first, so that they start thinking of things like "wow it would be great to not have to constantly rewrite this all the time" I think the NEED makes it easier to understand.

The only way to test the basics would be to take a practice AP exam :P It'll give you a good sense of how the test is, and you'll learn how you should pace yourself (too fast, too slow). And yeah, you have to pay close attention to the details in the multiple choice. Once you know how they trick you, then you can spot the tricks on the test and not miss the multiple choice. As far as gridworld goes, I can't remember all the classes exactly (we don't use it at all in Comp Sci II), but make sure you know how each class behaves (with their "move" methods and such). I think one or two of the free response will be about gridworld. I'm pretty good with Java (I'm working on a working Monopoly game in CSII :) ) so feel free to ask me anything.

My advice: practice a lot. It definitely was hard for me. Then you have to go through this:

select client.clientno, nameclient, description from client full outer join order ord on client.clientno = ord.noclient full outer join orderline ol on ol.orderno = cmd.orderno full outer join product prod on prod.prodno = ol.prodno

Java doesn't have pointers, only referenced objects. No way Java can compare to the true amazingness of C++ pointers. You can literatly put mothod pointers in arrays. Of course, misuse of pointers would get you a lot of bugs/memory leaks.magicalclick
VOID POINTERS FTW Oh and to TC, gud luk.

JIT93
1) There are no pointers, this is Java silly! :P 2) If you haven't taken recently taken APCS (like if you took it last semester) I suggest you study for it. Hell, even if you are taking it now, study for it anyways. I took it in the Fall semester, the test was in Spring, I did no studying/preparation or even did any coding between that time period, and I failed it hard. If you have a lot of experience outside of class with coding in Java, you should do fine, but either way you should: 3) Study the GridWorld case study. There aren't many questions about it on the test, but there is a sizable amount of points at stake involving it.

I ALWAYS use that syntax. In fact when I look at someone else's code and it's not formatted that way, it'll drive me bonkers.

Obviously stackoverflow after for wating awhile. or range out of bound exception based on Java, which needs to be test to be sure.

return (mystery(x-1)); System.out.println("MAY THE SOURCE BE WITH YOU"); Just switch dem two lines and it worx Assuming x is one or greater at start. PRE CONDITION lulz

AP Us History and AP Euro were both pretty easy for me. If you get like half the multiple choice questions right and write moderately good essays, usually that is enough to get a 3.
