If you want to become a rich, do not work for others but make others to work for you.
It is mentioned in java fundamentals that conversion from any class, interface or array type to a null reference is possible.Please explain this statement with an example I'm not completely sure what the author of that statement means, but I'd guess they're trying to explain that any reference in Java could possible refer to null. MyObject o = null; MyInterface i = null; MyObject a = null;
