What was the problem here.

Answer 1

You can move `enum Size` inside `Test` class, and modify its access level to public.

Then inside Main.main() method, you can refer the enum by specifying the owning class - `Test` - as follows ...

Test t1 = new Test(Test.Size.MEDIUM);
t1.orderPizza();

Answer 2

I'm not sure why this works, but if you move enum Size definition after the
class Test definition, the error goes away...

class Test{
...
}

enum Size{
...
}

class Main{
...
}

Answer 3

Bob_Li is right.
Usually we would place each class in a separate file. In Sololearn we cannot do that and the mechanism that separates and compiles our single file, is a little wacky. So the order of the classes makes a difference.
