HelloWorldApp Error

[iDGames]

Hey there!

I decided to give programming with Java a go and the first thing I wanted to do was this: "Hello World!" for Microsoft Windows (The Java™ Tutorials > Getting Started > The "Hello World!" Application)
However, when I was about to compile my first file by typing javac HelloWorldApp.java I receive this error:
"'javac' is not recognized as an internal or external command, operable program or batch file"

According to the Common Problems Lesson I simply need to tell Windows where to find javac. In my case the directory would be:
C:\Program Files\Java\jdk1.7.0_04\bin\javac

But as soon as I precede javac with this directory I get the exact same message again.

Here's my Command Prompt log:

Any help is appreciated!

According to the Common Problems Lesson I simply need to tell Windows where to find javac. In my case the directory would be:
C:\Program Files\Java\jdk1.7.0_04\bin\javac

That is not a directory, that is the name of the file itself (without an extension).

kind regards,

You're right about that. But the sample solution to compile the HelloWorldApp.java file is:
C:\jdk1.7.0\bin\javac HelloWorldApp.java

Wouldn't the equivalent for me be:
C:\Program Files\Java\jdk1.7.0_04\bin\javac HelloWorldApp.java
?

No; MS Windows is quite funky when it comes to spaces in a file path; for one thing, that shell (cmd.exe) chokes on it. Better put that directory in a PATH variable and never think about it anymore.

In the My Compute Settings,goto Advanced and click on Environment Variables.If a variable named PATH already exists then add a semicolon to its end and the add "C:\Program Files\Java\jdk1.7.0_04\bin" (without the quotes) to it and click OK.If no PATH variable is present,then just click on New and put the same Location and click OK
