In this blog, we will learn about various Visibility Modifiers or access specifiers like public, protected, internal, and private in Kotlin. In a programming language, the concept of Encapsulation is implemented with the help of access specifiers or access modifiers. The above process is called Encapsulation because all the information related to a particular department is grouped and no one is allowed to access it unless granted the access. The employee from the accounts department should first contact some officials from the library department and that officer will provide the required details. In this case, the accounts department should not be allowed to directly access the information of the library department. But a situation may arise when an employee from the accounts department requires the information of the library department(maybe details of fine). All these departments have their information.

In school, we have various departments like the accounts department, library department, faculty department, student department, etc. It is the process of wrapping up of data and information under a single unit.Ĭonsider an example of a school management system.

Encapsulation is one of the important features of object-oriented programming.
