    Can you do a "dir" command in that directory, and post the results here?

    Also: Java is case-sensitive. System != system.

    You need to navigate to the directory where the source file, First.java, has been stored by your editor. Once you find the directory that it was stored in (can you do that?), use the 'cd' command to navigate to that directory, and try your command again.

    wuth an example i can make you understand. let the path of your folder is e:/java/program, where program is folder in which your programs are stored.

    then in cmd prompt u'll use:

    c:/> e: //to enter in e drive (or anyother drive where folder is)
    e:/>cd java
    e:/java>cd program
    e:/java/program> javac first.java //to compile
    e:/java/program> java first

    hope ,this'll help you..!!
    BEST OF LUCK..!!

    Default Re: My first program

    Looks like the OS can not find the javac.exe file. The folder that holds the javac.exe (usually bin) needs to be on the PATH environment variable. Do a Search for how to add a path to the PATH.
    If you don't understand my answer, don't ignore it, ask a question.
