What do you mean by data encapsulation?
Data encapsulation is a bundling the data, and the methods in Java. The data or variable should always be private, but method of function may be public. If we declare variable as private then it is called data hiding.
Data encapsulation is an object-oriented programming concept that involves bundling data (variables) and the methods that operate on that data into a single unit, usually a class, while restricting direct access to the internal details. It helps protect data from unauthorized modification by using access modifiers like private and providing controlled access through public getter and setter methods. This improves security, maintainability, and modularity in software development.
