Let’s see one moreexample of abstraction in Java using interfaces. In this example, I am creating various reports which can be run on demand at any time during the application’s lifetime. As a consumer of the report, a class needs not to know the internals of the report’s run(), ...

As I understand, abstraction refers to hiding the internal details of the program while exposing the interface to other programmers without worries of internal details. But, I don't understand How abstract classes fit into this concept of abstraction, where abstract class asks me to implement the...
let’s actually go ahead and implement the coffee machine example in Java. You do the same in any other object-oriented programming language. The syntax might be a little bit different, but the general concept is the same.

In Java, abstraction and encapsulation help in creating abstract actors in the system. Encapsulation is the realization of abstraction.

Predicateion maps the concrete states of a program tostates defined by the valuation of a finite set of input predicates. Boolean program describes thetransfer function for a predi-cateion. In this report, we propose a tech-nique for automatic predicateion of single-threaded Java programs. We...
