Document Summary

Encapsulation is one of the fundamental concepts in object-oriented programming (oop). It describes the idea of wrapping data and the methods that work on data within one unit. This puts restrictions on accessing variables and methods directly and can prevent the accidental modification of data. To prevent accidental change, an object"s variable can only be changed by an object"s method. Those types of variables are known as private variable. A class is an example of encapsulation as it encapsulates all the data that is member functions, variables, etc. Consider a real-life example of encapsulation, in a company, there are different sections like the accounts section, finance section, sales section etc. The finance section handles all the financial transactions and keeps records of all the data related to finance. Similarly, the sales section handles all the sales-related activities and keeps records of all the sales.
