    Question How to make NP++ Compile and Run Java programs

    For a while I just used command prompt to compile my code but it's just starting to get annoying having to open it up every time. I tried using NPPexec to do it but I just keep getting this message

    Input:
    cd desktop
    cd code
    javac $(FILE_NAME.JAVA)
    java $(NAME)
    Output:
    CD: desktop

    Does the program's doc discuss what version of java it needs?

    Are you talking about JRE or JDK?
    How many versions of the Java do you have installed on your system?
    I'm not sure that they are compatible. The installations could walk on parts of earlier installations.

    I started out using Six. But then when I swapped to eight and uninstalled six. I have java eight JDK and JRE installed as when I used the installer it installed both of them onto my system.

    Can you open a command prompt and enter:
    javac -versiom
    java -version

    copy the contents and paste it here.

    Why is java looking for 1.7? Where did that come from if you only have installed 1.6 and 1.8?
    but '1.7' is required.

    javac -version
    javac 1.8.0_191

    java -version
    java version "1.8.0_191"
    Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
    Java HotSpot(TM) Client VM (build 25.191-b12, mixed mode)

    And I do not know why java is looking for 1.7

    I'm sorry for posting on a closed topic. So I tried the fixes and none of them worked.But I think this is how NPPexec handles as my java works just fine normally.
