Determine the best access modifier for each of the following situations: a. a class employee records the name, address, salary, and phone number. b. an adding method inside of a class basicmath.

a. Protected

b. Public

Explanation:

There are four acess modifier in Java.

Default: Acessible only within the same package.

Public: Can be acessed by any class.

Private: Acessible only within the class.

For example, you have a class employee and a private method. This method can only be accessed by an object that is an instance of an employee.

Protected: Used in classes that extend each other. For example, a class of employees would extend employee.

So:

a. A class Employee records the name, address, salary, and phone number.

The best acesses modifier is protected. A class may extended employee but have the same arguments(name, adress, salary, phone number), so it should also have acess to the method.

b. An adding method inside of a class BasicMath.

This method can be used in a variety of packages and projects and classes... and there is no important information regarding security. So the best method is public.
