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.

From http://www.webopedia.com/TERM/e/encapsulation.html : In programming, the process of combining elements to create a new entity. For example, a procedure is a type of encapsulation because it combines a series of computer instructions.Likewise, a complex data type, such as a record or class, relies on encapsulation.ncapsulation is a word that gets bandied about a lot in discussions on wiki, and it almost always is being misused as a synonym for abstraction or information hiding. (I do it too.). To give a concrete example of the differences: 1  a java interface provides an abstraction.
