Question
methods that should be used by any object that wants t change or retrieve the value of a data member.
Solution
To change or retrieve the value of a data member, an object should use the following methods:
-
Getter method: This method is used to retrieve the value of a data member. It typically has a prefix of "get" followed by the name of the data member. For example, if the data member is called "name", the getter method would be "getName()". This method returns the value of the data member.
-
Setter method: This method is used to change the value of a data member. It typically has a prefix of "set" followed by the name of the data member. For example, if the data member is called "name", the setter method would be "setName(String name)". This method takes a parameter that represents the new value of the data member and sets it.
By using these getter and setter methods, objects can safely access and modify the values of their data members. This encapsulation ensures that the object's internal state is controlled and prevents direct access to the data members from outside the object.
