  • Try better subject, please!

    The javac (javac.exe) is in jdk's bin directory, e.g. c:Program FilesJavajdk...injavac.exe
  • It sounds like you need to update your PATH variable. Here is how you do it.
    Right click on My Computer, click properties, then advanced, then environment variables. Next, find the variable named PATH. Click the edit button. Move your cursor to the end and type
    ;C:Program FilesJavajdk1.6.0_14in
    Be sure to type the semi-colon because that seperates the the different parts of the PATH variable.
    Don't feel embarassed, all beginning Java programmers have the same problem. I think Sun Microsystems should fix it to automatically update the PATH variable. If you need anymore help let me know.

    System.out.println("Over and Out");
