Hi guys I'm new, I'm trying to compile and run a program from the command line to learn. I'm having difficulty with the running part, I keep getting these messages:
Error: Could not find or load main class .\main\java\org\example\App.class
Caused by: java.lang.ClassNotFoundException: /\main\java\org\example\App/class
I compile using javac and goes fine, then I try to run it but to no avail, I tried from the src, from the root but nothing ... can't seem to find the file... why?

use dots instead of slashes. And don't use extension .class

so it will be java org.examplse.App
