why cant i start my program in the console?

[kelvin cheung]

run, cmd and type :

java myprogram

i am on the right directory that my class file is.

The class name is case sensitive - even in a Windows environment. Does your class start with a capital letter?

What kind of error message do you get? (Word af advice: Don't just say "it doesn't work" or "it doesn't start", say specifically what you're doing, what you expect to happen, and what actually happens, including all error messages.)

Is the current directory part of the classpath? Maybe you need to type "java -classpath . myprogram"

Kelvin,

Have you compiled your program?

javac Myprogram.java

Oops. Just noticed you put 'class file' in your post.
The excitement of my first reply to a post got the better of me!

Hi Kelvin,

I think your PATH variable is not set properly.

  
echo %PATH%

make sure you have C:\<JDK>\bin directory in the path.

HTH,

As you work through this, see if THIS helps. I'm looking for feedback on how to make it better, so let me know if it doesn't!

[kelvin cheung]

i did not know that I needed to set the path.
thank you all!

by the way,
Stan James: you got a very helpful page!

That's a great reference. You should add a link to it from the JavaRanch FAQ.
