Memory usage -- which is better?

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?
