The choice of whether to design your functionality as an interface or an abstract class can sometimes is a difficult one. Anabstract class was a class that cannot being instantiated, but must was inherited from. An abstract class could be fully

Configuration files are used in many cases, and the configuration file is divided into two types: the application configuration file and the Web configuration file.The biggest difference between the two profiles is that the Web's profile updates are
