public class Manager : IPerson { ... } If a class extends or derives from another class, it inherits all members and implementations from the parent class. If a class implements an interface, it must provide its own implementations for the methods defined by the interface (although in C# 8....

is an interface that contains a lot of methods, so there is an abstract classthat provides a skeletal implementation for all the methods of List interface so that any subclass can extend this class and implement only required methods. We should always start with an interface as the base and ...
Always remember that choice between the interface or abstract class is not either/or scenario, where choosing anyone without proper analysis would yield the same results. A choice must be made very intelligently after understanding the problem at hand. Let us try to put some intelligence here. 5....
interfaces provide a distinct separation between the functionality and the implementation details. it enables a class to alter its internal processes without affecting its users, as we define the method and the signature separately. 3. @interface in java, we use @interface to declare an annotation...
It must have the phrase "implementsInterface_Name" at the beginning of the class definiton. It must implementallof the method headings listed in the interface definition. Abstract classes and inheritance With an interface on the other hand, the relationship between the interface itself and the class...

This document describes the configurations of QoS functions, including MQC, priority mapping, traffic policing, traffic shaping, interface-based rate limiting, congestion avoidance, congestion management, packet filtering, redirection, traffic statistics
Now you may be wondering why not declare an abstract class as an interface, and have the Dog and Cow implement the interface. Sure you could - but you'd also need to implement the eat and sleep methods. By using abstract classes, you can inherit the implementation of other (non-abstract...
