Core Java Programming Course- Data Encapsulation

The video tutorial explains the concept of data encapsulation, a fundamental principle of object-oriented programming (OOP). It highlights the issues of direct access to class member variables and demonstrates how to create a class with member variables and methods. The tutorial further explains how to use getters and setters to encapsulate data, preventing direct access and reducing maintenance issues. This approach ensures that changes to variable names do not affect other classes using the class, promoting better programming practices.
