What is the purpose of a bare package declaration, and what does it do?

Question

What is the purpose of a bare package declaration, and what does it do? As in:

package;

class Main {
    //...
}

Answer 1

package; communicates that you are so-called "top-level", that means, you are not actually in a package.

You can leave it out, so this will work too:

class Main {
    //...
}

If you are in a package, it is required to define the type path at the top of the file, eg. package foo.bar; (where foo.bar is a folder foo/bar in a source path, defined by -src )
