    Default My first java code won't run from cmd Windows

    Hi.

    I'm a totally beginner in java and was wondering if someone could help me out

    I have made an easy java file, but can't run it from cmd - windows.

    Can someone tell me why I'm not able to run the file?

    My commands with error message:

    C:\Program Files\Java\jdk-17.0.2\bin>set path=C:\Program Files\Java\jdk-17.0_2\bin

    C:\Program Files\Java\jdk-17.0.2\bin>cd\

    C:\>dir
    Volume in drive C has no label.
    Volume Serial Number is 7048-6868

    'java' is not recognized as an internal or external command,
    operable program or batch file.


    My code looks like this:

    public class FirtsJavaProgram {
    public static void main(String[] args){
    system.out.println("This is my first program in java");
    }//End of main
    }//End of first JavaProgram Class


    Thanks!

    'java' is not recognized as an internal or external command,
    The OS can not find a command named java.

    You need to
    either give the OS the full path to the java command; for example:
    C:\Program Files\Java\jdk1.8.0_60\bin\java.exe TestCode27
    or add the path to the bin folder to the OS's PATH environment variable so the OS can find the java command

    Note: You need to run the javac.exe command to compile the source and create a .class file before running the java command.
    If you don't understand my answer, don't ignore it, ask a question.
