Encapsulation vs Data Hiding - Java

Question

The way I have understood encapsulation is 

 

“It is a mechanism to hide information from the client. The information may be data or implementation or algorithm. We achieve this using access modifiers.

 

It’s more like data hiding. I want to know how do we achieve encapsulation in Java other than ‘Access Modifiers’? 

Answer 1

Encapsulation is bundling the data with the operations you perform on that data. It encapsulates the data - fields and methods for manipulation of data. 

The bundling of data and methods is to hide the implementation which sounds more like data hiding as you say.  

But a  better way than to use methods and make all fields private is interfaces. It provides a total abstraction. The object which will be created is based on the class which is implementing the interface. This way it hides all the fields and methods internally.
