A  java file is the code file   A  class file is the compiled file   It s not exactly  conversion  - it s compilation  Suppose your file was called  herb java   you would write  in the command prompt      javac herb java   It will create a herb class file in the current folder   It is  executable  only if it contains a static void main String    method inside it  If it does  you can execute it by running  again  command prompt     java herb

Use the javac program that comes with the JDK  visit java sun com if you don t have it   The installer does not automatically add javac to your system path  so you ll need to add the bin directory of the installed path to your system path before you can use it easily
