Encapsulation vs Data Hiding - Java

Question

Interviewer: What is encapsulation and how do you achieve it in Java?

Me: Encapsulation is a mechanism to hide

Answer 1

Data hiding means we are providing security to data within the class.

Abstraction means hiding the code by defining member functions.

Encapsulation is the combination of abstraction and data hiding, means we are wrapping data and code associated with that data. For ex bean class

    class student {
private int age;  // Data Hiding 
public setAge(){} // Abstraction 
public getAge(){} // Abstraction 
}

student class is encapsulated.

encapsulation = data hiding + abstraction
