Hi jimgym1989! Welcome to bytes.com!

It's great to have you here!

When you post, please always keep to the Posting Guidelines and when you post code, please post it in [code] ... [/code] tags. (I've added them for you this time, please use them yourself in future.)

In this post, you have used capital letters in everything you wrote apart from the code. This is against our rules, as the use of capitals is generally considered to be shouting and therefore rather rude. So please, even if you're angry at your code or your computer or whatever, do not use capitals in that way.

About your question, how do you "run your program"? Are you using an IDE (e.g. Eclipse, Netbeans, ...) or did you write your code in an editor (e.g. Notepad)? Your code is probably correct (as you say it does what it should), but the way you call it may not be.

Otherwise, I'll just wish you the best and hope you enjoy being part of bytes.com!

Hi Nepomuk!! thank you for your immediate response..im very sorry..i haven't read the post guidelines...

No problem, as long as you've read them now. ^^

anyways it wasn't my intention to be mad on something, i just make it capital so that you'll be able to see my questions properly..hehehe..

Well, that's what the [CODE]...[/code] tags are for.

im using JCreator..I just copy paste my code on this textfield..how do i properly call the method or a class..

JCreator should have some kind of "run" button and some kind of console. If you run a very simple class like this:

public class HelloWorld {
   public static void main(String[] args) {
      System.out.println("Hello World");
      System.in.read(); // This is just to make sure, that the console window doesn't close immediately
   }
}

then the output "Hello World" must be printed somewhere. That place is a replacement for the command window. You can however start your class from a "proper" console too - open one (in Windows: Start -> Run -> "cmd" -> Enter -> cd /d "path/to/my/project") and then start your program with java -cp yourClasspath youClass

Glad to hear that. Happy people are especially welcome here! :-D
