ok i am new at this and in class we use the command promt on windows to run java. Now i am at my own computer and i go through the steps that we do in class. That is going to the directory doing the set classpath=. then i do the javac and the message is "'javac' is not recognized as an internalor external command, operable program, or batch file." if anyone knows what i can do to run off of the command prompt it would be very helpfull. thanks

Hi Scott,
Welcome to JavaRanch!
First, you'll need to have the Java Developer's Kit installed -- you can get it from If, after downloading and installing the J2SDK, you still have this error, then you need to use the "System" control panel to add the "bin" subdirectory of the J2SDK installation directory to your PATH environment variable.

It is sorta covered in the JavaRanch Style Guide.
