OK thanks

Pay attention to steps that are following installation self - there is a need to update registry to set Java/JDK home path.

thank you, how do I go about fixing this

Answer 5

have you ever tried to confirm your environment is good to be used for programming by input javac in your command prompt

Answer 6

you need to set up your JaVA path correctly and confirm it from your command prompt if indeed it's been set by input javac

Answer 7

yes, I fixed my issue. I don't remember how, but I am now able to run code easily through my cmd window or netbeans

Answer 8

I think I. just reinstalled & filled the installation instructions word for word

Answer 9

While I'm using Linux and you are obviously using Windows the errors are self-explaining - your installation of Java is not correct. Probably you did not set JAVA_HOME correctly.

Answer 10

As I wrote - I'm do not using Windows - but you should read Oracle's Java installation instructions carefully and literally do what it says.
