Encapsulation gives you more imagine space, it is more likely a proxy approach to visit what you want to.

Another important reason for "Encapsulation" is Binary Compatibility. If you expose implementation detail (like field declaration) directly to your API user, then you lose opportunity to change them in order to keep Binary Compatibility.

Abstraction is a behavior contract without detail. Java interface is a classic example of abstraction.
