Memory usage -- which is better?

[Kev Adams]

I came across some code today that looks like this:

someMethod( getObjA().getObjB().getObjC().getName(); getObjA().getObjB().getObjC().getAge() );

Would it not be better, not only for readability, but for memory usage to do it like this:

ObjC objc = getObjA().getObjB().getObjC();
someMethod(objc.getName(); objc.getAge());

My thinking is that Java has to create a temporary memory space to hold whatever is returned by getObjA().getObjB().getObjC() each time.

Is that correct?

Performance / memory use is not the issue here, the ability to debug and maintain the code is.

If any of those compound statements threw a NullPointerException, where would you look?
