Unable to run java with command line arguments

Question

I have been trying to run Java with command line arguments, but for some reason the class can not be found. I am very certain the directory is correct. Is there any way to fix this?

CLDemo.java file

public class Demo {
    public static void main(String[] args) {
        System.out.print("It works!!!");
    }
}

Answer 1

You need to do cd out\\production before java CLDemo .

The default compile output of IntelliJ IDEA is under out\\production folder, and Java needs to run at the corresponding package (folder) of your compile output.
