Motivation:

"Indirect access variable": supports more flexible data acquisition methods, such as lazy Initialization (meaning it is initialized only when a value is used .)

"Direct access to variables": the code is easier to read and does not need to be stopped. "Ah, this is just a value function ".

Choice: 1. Code specification, according to the practices of most people in the team.

2. individuals prefer "directly accessing variables" until this method brings trouble.

Example of martin (author): If you want to obtain the field in superclass, but want to change the field to the calculated value in subclass, Self Encapsulate Field should be used most.
