One small question. I seem to be having technical difficulties when trying to compile my java program. The course study book I am using says to use the comman "javac (file name)" to compile my .java file. However when I type in the said command, windows command prompt replies "error: cannot read file". I do not know what is wrong. I have the paths defined, as far as I know and the file extensions are correct. I just don't understand why it will not read the file. I'm using Notepad to input the code and Windows Command Prompt to execute the J2SE SDK v1.4.2 javac program. I thought I might be missing a few java files, but I am not sure. There is no troubleshooting section of this book. I don't know how much help I will receive here, but any I would appreciate. Thanks.
