Why is it not recommended to make all of a class’s variables public?

Here is the answer of the question: Why is it not recommended to make all of a class’s variables public?

  • Doing so makes your code tightly coupled.
  • The attribute may be accessed only by the class that defines the member.
  • You will have no control over which values the attribute can take. Any external code will be able to change it without any constraint.
  • You can then access the attribute only within the class itself, and by inheriting and parent classes.
