Hello,
I finally had time to go past the HelloWorldApp in the tutorial. :D
Now I'm trying to create my own classes then run them through my
interface...
But I'm a little confused:
The HelloWorldApp had everything in it. It didn't need a interface,
why do we need to make a separate interface for all our other classes?
Why do we have to create an interface when the class already has
the same code in it?
Do you save all classes as a .java file then use javac to compile
it into a .class file?
What do you save interfaces as?
I created a class for my heater:
/** creates the class for heater which has temperature, speed and onOff
*/
class Heater }
int temperature = 0
int speed = 0
int turned = on
voide changeTemprature(int newValue) {
temperature = newValue;
}
voide speedUp(int increment) {
Speed = speed + increment;
}
voide slowDown(int decrement) {
Speed = speed - decrement;
}
voide turnOn() {
Turned = on;
}
voide turnOff() {
Turned = off;
}
voide printStates() }
System.out.println("temprature:"+temprature+" speed:"+speed+"
turned:"+turned);
}
}
Where do I put the lines like:
public static void main(String[] args)
and
System.out.println
?
Also do I have the right idea with the word after void is the word
I type to turnOn the heater?
And the word after (int is the word that could be what ever I want
it to be, it just needs to be the same below?)
Example:
voide slowDown(int pizza) {
Speed = speed - pizza;
}
?
If you have any question, the interface for the heater is:
interface Heater }
voide changeTemprature(int newValue);
voide speedUp(int increment);
voide slowDown(int decrement);
voide turnOn();
voide turnOff();
}
Sorry, I didn't see answers to these questions in the tutorials and
I need to know this to do anything!
Sad smile emoticon
Thank you,

That's not learning a language Ken, that's learning an SDK, which
implies one already knows how to use the language.
I think you should start off with text as well, so that six months
later you aren't asking basic questions like why doesn't this class
run, because you never had to put a mian method in it since Eclipse
always did that for you, etc. etc.
Of course, that implies that you actually want to learn the
fundamentals of the language, and not just code.
Take care,
Sina

I have to disagree with this. There is nothing like using eclipse
when you're learning a language. Let's say you are in Android and
need to make an Application. Ok so you start it up and there is an
Activity class. You're in your text editor what do you do?
You go out on line or into a document and try to read up on all the
possible functions you can run in an activity. Not bad but why
not make it quicker.
Just arrow to your myactivity and use the source menu and go down
and select override members. Then you can arrow through the list
of things you have that you can do in that class. You check a few
and tab down and hit ok. Now you have 6 stub functions that work
perfect. You then go down to the keydown function that you just
added and arrow over keyEvent and select help it tells you all the functions
Eclipse and Visual studio are not just environments but they
are great learning tools. Not to mention learning the environment
now with an easy program will speed up both development of a
harder program but it also teaches you how to download other
peoples projects and get them running.
Heck for that matter if you don't use eclipse you have to learn
another way to compile your project. Which normally means you
start compiling at the command line with javac. That sounds easy
but how many of you have tried this and ran into the java path
problems. That is not something you want to get a new user into
right away. Then if you want to get real bold and use ant as a new
programmer you better have a lot of antacid.
So I guess in short I just wanted to say sure Eclipse is a big pig
but the gains for a new coder is pretty high if you learn to use
it. Now if you're on a Mac sorry to hear it while I like Mac I
have not been impressed with the amount of work I had to go through
to get Eclipse set up. I use it on both Mac and Windows but I will
tell you there is nothing like Eclipse and Jaws 12. I use no
scripts and do just fine.

Hi Brandon,
This is my opinion, so take with a grain of salt. Right at the
beginning with Java, I feel that you should use a text editor.
Personally, I prefer EdSharp, but there are lots of good ones.
Learn to use the command line tools that come with the Java
Development Kit. After you have written some programs, and you know
what's going on with basic Java, start to use something like
Eclipse or Net Beans. I have no experience with SodBeans, but I
understand that that package for NetBeans is making a big
difference in NetBeans accessibility. So scrap fancy editors for now.

Thanks and I started reading those, the only problem is I use
Eclipse and these talk about the Netbeans IDE which I think it is
inaccessible.
My big question is: What are all the differences in the different
things you can create with the new menu in Eclipse? There are like
projects, classes, Java projects and all kinds of other things that
aren't really talked about with Java.
Thanks,

Hi,
I think that, as with many things, this is one of those things that
can be different, depending on the learning style and knowledge of the person.
Speaking just for myself, I get more out of tutorial style books,
when I'm learning a language. I tend to freeze up at reference type
material that is full of code and short on words, but that's my taste.
According to me, you will probably do well with the nutshell books,
if you already know lots of programming concepts and want to see
how certain things are done in Java. On the other hand, you may do
better if you have little programming experience by looking at the
Java Tutorial, which takes things a concept at a time and explains
them with lots of words and examples. You can see that at
<http://download.oracle.com/javase/tutorial/reallybigindex.html>http://download.oracle.com/javase/tutorial/reallybigindex.html.
Thanks.

I would recommend if you have a subscription to bookshare.org, that
you download a copy of "Java in a Nutshell". It is a nice summary
of features with some examples. I was going to read "Thinking in
Java, 4th edition", which I forked $25 for online, but got a
package that I cann't display on my system. I have been unable to
read more than the preface, and most the time, the html just
freezes things. So I'm pitching it. A shame as it sounds like a
useful guide to using java the way it is meant to be used.
Online there are also common tasks implemented in java, which you
can find in <http://commons.apache.org/>http://commons.apache.org/
Good luck and happy hacking.

Hello Brandon,
Do you have any form of IM or perhaps skype? I would like to help
you but it's easier for me to recommend something if i know a bit
more about your background.

Hello,
I'm new to programming, (I have just made it past "Hello World")
and am looking for some guides.
I would like to learn Java, but I'm not quite sure where to start.
I downloaded the 500 or so documents from the "Java Documentation" at:
<http://www.nonvisualdevelopment.org/node/20>http://www.nonvisualdevelopment.org/node/20
as well as reading all the tutorials on Eclipse and Java.
I've installed the SDK 1.6 and Eclipse, is there anything else I
need? I see there are Jaws scripts for Eclipse, where do I insert those?
I arrowed through the 500 documents dealing with Java and found:
Java Tutorial 3rd Edition, a short course on the basics
but I see it was written in 2001 and only deals with Java 1.3 and
Windows 2000 and before. Is this something I should read? What
books best describe the language in an exciting and useful format?
I'm wanting to eventually program for Android, but I think that is
stepping a little ahead of myself.
Where do I start?
Thanks,
Brandon Keith Biggs
