simple instantiation from Mughal book

Hi All,
The code below contains two classes, and an inerface. In class Planet, shouldn't the Star object orbiting be instantiated before it can use the method describe()? Without instantiating the Star class it compiles, but gives a NullpointerException, as it should, during execution. Can someone please tell me if I am right?
Mughal keeps a nice Errata page, but this isn't on it, so I am curious as why it isn't.


TIA,
-Jarrod

You're right.
 
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
