A donor valve can be expected to last 10-20 years. Tissue Valve (sometimes called âbioprostheticâ valves) Tissue valves are created from animal donorsâ valves or other animal tissue that's strong and flexible. Tissue valves can last 10-20 years, and usually don't require the long-term use of medication. For a young person with a tissue valve replacement, the need for additional surgery or another valve replacement later in life is highly likely.
Inheritance, encapsulation, abstraction, and polymorphism are four fundamental concepts of object-oriented programming. This article focuses on inheritance. Encapsulation, abstraction, and polymorphism are covered in other articles.Please read Object-oriented programming concepts: Objects and classes and Object-oriented programming concepts: Writing classes if you have not already done so.his article focuses on inheritance.

Encapsulation means hiding the internal details of an object, i.e. how an object does something. Encapsulation prevents clients from seeing its inside view, where the behaviour of the abstraction is implemented.Encapsulation is a technique used to protect the information in an object from the other object.Hide the data for security such as making the variables as private, and expose the property to access the private data which would be public. So, when you access the property you can validate the data and set it.ncapsulation is a technique used to protect the information in an object from the other object.
