I'm as green as you can have it and I need your help!

['goke70]

Does it matter where I save my source file? I can't seems to get to get to it in the command prompt when I try to compile it. Please help. I am working on JDK 7.1 and window 7

[Norm]

You should create a folder for your java source.
If you are using command prompt to compile, you need to learn how to use the cd command to change directories to be in the folder with your source files.

I am working on JDK 7.1 and window 7

I suppose you mean Windows 7.

Shift+Right-click --> Open command window here.

I did create my java source, but every time I try to direct it there, I get "could not find or load main class ExampleProgram (which is the file I am trying to compile) what i'm I doing wrong?

['goke70]

Yes Darryl, I meant WindowS 7

[Norm]

Copy the full contents of the console window that shows what you entered and the response and paste it here.
Also do a dir command to show the contents of the directory.

To copy the contents of the command prompt window:
Click on Icon in upper left corner
Select Edit
Select 'Select All' - The selection will show
Click in upper left again
Select Edit and click 'Copy'

Paste here.

What was post#7?

You should not be in any of the folders that are part of the JDK!!!
You need to create your own folder for your java source files.

Your console log does not show where you tried to compile the ExampleProgram.java file?

Take a look at this:
"Hello World!" for Microsoft Windows (The Java™ Tutorials > Getting Started > The "Hello World!" Application)

['goke70]

thanks, the information looks promising, I will give you a feed back after i go through it.

'javac' is not recognized as an internal or external command,

The OS can not find the javac.exe file. It looks in the folders on the Path to find .exes etc.
Most people add the path to the folder that the javac.exe file is in to the Path Environment variable.
There are many posts on how to do that.
Google or Search here.
