No, you don't.

Java doesn't have globals.

That isn't even 'static', much less "global".

Stop calling that "global".  It's the very opposite of global.

Creates a new instance of 'Mortgage', then assigns the pointer value (*not* the object) to 'q'.

Whatever pointer value 'q' used to hold is now gone from 'q', erased by the new pointer value.

Yes, I am repeating what others have been saying.
