Simple Java Tut (1)

Java is a programming language that is growing rapidly. It is basically based on C/C++. If you know C, java will be a breeze for you, literally. Java is like a second gereration of C/C++.

First of all, we need a program that  can compile Java programs that you write. I suggest getting JCreator. It is a free program that you can download from the JCreator website. Go to http://www.jcreator.com/download and download the JCreator Classic version (3rd program on the list), Java api documentation (last program on the list), and (if you don't already have the development kit) download the Java development kit. (for help on exactly how to download all these stuff, go to http://thecodingzone.com/index.php/topic,4203.0.html

Hopefully I don't have to tell you how to run the .exe file that you downloaded

I suggest making a new folder somewhere in yor My Documents and keeping all your files and programs there.

Code:

// defining a class
      public class FunnyThings
          {
           public static void main (String[] args)
                 {
                 // display
                   System.out.println(" Some things that Bob thinks are funny");
                   System.out.println(" Clowns, Drug-adicts, Slaytanist");
                  }
         }

Those curly braces are necessary. If you forget to close the braces, it will give you an error message. If you misplace them, it will give you an error message as well.

So, if you compile the code above, a dos screen will pop up and give you...

Code:

Some things that Bob thinks are funny
Clowns, Drug-adicts, Slaytanist
Press any key to continue....

If you already couldn't tell, Java and JavaScript are very alike. Basically JavaScript is a programming language that was derived from Java. Java is a stand-alone programming language, but JavaScript isn't. (Yeah, like you already didn't know that  )

That's all for today guys. I'll try to post some more tutorials later.

Java is like a second gereration of C/C++.

Not at all. They're for completely different things.

Nice tutorial though : )

not really, they are very....veryy.....VERY....similar. peps at sun microsystems basically took C and made it better lol, dat is wat my teacher told me

ty btw

Your teacher is wrong : )

No probs though, it's a good tutorial.

Haha, slay is basically married to C


Does JCreator come with the JDK [java development kit]?

And you should write a tutorial for writing java applets, since it seems to be what it's best known for.

To say the least...

Anyhow, nice tutorial -- but, add more ;p I was getting back into the mood, "OOP" isn't that bad I guess... and then it ended.

IMO, OOP is a mood.  I have to get a feel for OOP again every time I decide to use it.

no it doesn't, u have to download the jdk fromt the sun's website

and for the applet, lets learn the basic stuff first. good applets usually need more than one class defined and the "formating" is kinda wacky, u know...

AMEN  to dat C + Slaytanist = <3 thing.

i didn't write dat much cuz i didn't know peps here were interested in java. i am really happy to see all the feedbaks lol.

If Java is anything like Javascript, then i would try to learn it...

Also, i've heard you can code Core JavaScript aslong as you import something called java.script :p That true?

i don't know about the core javascript thingy, but java and js are very similar. as i said b4, java is a stand alone programming language, but javascript isn't. Java and JS are very similar. if u know java, or javascript, learning the other wud be easier. so, u can look into it, u'll understand a lot. i know some java and i can basically look at a js code and folo along.

Isn't it - public static void main (String[] args)?

String should be caps and that's the array.

oh ty ken. string sud be String, but i don't think it matters if u pud String[] args or String args []. not sure. i'll double check and fix it.

fixed, and u were rite.

I know I'm right because my teacher made the same mistake and I corrected him.

BTW, you didn't capitalize String.

grrr....ty again, this dam book i have is messing my whole brain up. i am reading it everywhere lol, cuz i have a pdf format and in my usb drive, learning to program java for dummies. it is a gr8 book.

Actually, I've been thinking about this topic quite a bit and I think I'll write a tutorial on this explaining the setup of JCreator a little more in-depth because other than that, I don't really see this as a helpful tutorial.
