Question

When defining a class, it is a best practice to declare ____ as private. constructors mutators nothing should be private accessors variables

Answer 1

The answer is "variables".

Step-by-step explanation:

It is necessary to declare a variable privately when declaring a class because the private variable 'protects' the code while it is in operation. It may not aim to protect it at this stage from changing the codes themselves for other developers. Its purpose of the so-called "data hiding" is to hold the internal data from many other classes using the class protected.
