Answer:

The answer is "variables".

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.
