Why can't I run my java Hello World program if it is inside a package?

Question

I created a file called \"Hello.java\" that looks like this:

public class Hello {
        public static void main(String[] args) {
                System.out         


        

Answer 1

Try java testpackage.Hello.

Because this is in your classpath, you should be able to run that from any working directory, but refer to it by its full name.
