create a class called person that has encapsulated variables
What is encapsulation called?
In object-oriented computer programming (OOP) languages, the notion of encapsulation (or OOP Encapsulation) refers to the bundling of data, along with the methods that operate on that data, into a single unit.
How do you encapsulate a variable?
Encapsulation can be achieved by Declaring all the variables in the class as private and writing public methods in the class to set and get the values of variables.
It is more defined with the setter and getter method.1 nov. 2023What is member variable encapsulation?
Member Variable Encapsulation
All data members should be defined as Private members of the Class in Object-Oriented Programming.
Setters and Getters functions should be used by any object that wants to change or retrieve the value of a data member.In Java, instance variables are encapsulated by using the private keyword.
This prevents other classes from directly accessing these variables.
