To subscribe to this RSS feed, copy and paste this URL into your RSS reader. I see your point. Interface provides contract between the parties, example, producer and consumer. As an example, at the top might be an interface with a single method, then the next level, provides several abstract classes, which may or may not fill in some of the details about the top level, but branches by adding their own abstract methods, then for each of these abstract classes are concrete classes providing implementations of all the remaining methods. You perform abstraction when you expose this class to client as. So, when you access the property you can validate the data and set it. for a person: you decide to keep first and last name and SSN. In Java, encapsulation helps us to keep related fields and methods together, which makes our code cleaner and easy to read. It is used to secure the data from other methods. Another way to think about encapsulation is, that it is a protective shield that prevents the data from being accessed by the code outside this shield. Thank you get the implementation code look at the object can oop in multilevel, they still novel and real world. Encapsulation in Java. As the name suggests, Object-Oriented Programming or OOPs refers to languages that use objects in programming. only show the essential features of the object.
