Yes, the original topic was arrays (objects) in a structure. To help clarify for the OP, I gave examples of what did or did not 
need to be explicitly initialized in a structure. Brian's response was to make a false statement which, to help prevent 
confusion, needed to be corrected.

The statement, "When you do a  mstrct = new mystruct it creates the structure with null pointers for those fields," does not 
refer to what happens in C. And, "those fields," obviously refers to "strings and arrays". As I explained, the strings would be 
automatically initialized, but the arrays would not.

Is there anything incorrect about the following statement?
Simple native datatypes (such as String, Integer, Boolean) will be automatically initialized. But, objects (such as String[], 
Integer[], Boolean[]), which are objects of classes and have properties and methods, must be initialized with the NEW keyword.
