Question

define the voicemail class's getgreeting() accessor that gets data member greeting and the getnumber() accessor that gets data member number.

Answer 1

Accessors for the voicemail class, getGreeting() and getNumber(), are methods that return the greeting and number data members of the class, respectively. They are used to maintain encapsulation by allowing external read-only access to these private class members.

Step-by-step explanation:

To define the getGreeting() and getNumber() accessors in a voicemail class, you will need to create methods within the class that return the values of the private data members, typically referred to as greeting and number. The purpose of an accessor, also known as a getter, is to provide a way to read data from an object without granting direct access to the data member itself, which helps maintain encapsulation in object-oriented programming.

Example of getGreeting() Accessor:

public String getGreeting() {
return greeting;
}
Example of getNumber() Accessor:

public String getNumber() {
return number;
}
Here, both methods are assumed to be part of a voicemail class that has greeting and number as private data members. The getGreeting() method will return the greeting, and the getNumber() method will return the number associated with the voicemail. Note that the type String might vary depending on how these data members are defined in your class.
