abstract keyword is used to create an abstract class and it can be used with methods also whereas interface keyword is used to create interface and it can’t be used with methods. Subclasses use extends keyword to extend an abstract class and they need to provide implementation of all the de...

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...
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. ...

Abstract classes are designed for inheritance, serving as blueprints for deriving new classes. They define a common interface and behavior that derived classes must implement. Sealed Class Sealed classes, on the other hand, prohibit inheritance. Once a class is marked as sealed, it cannot serve as...
Abstract classes and inheritance With an interface on the other hand, the relationship between the interface itself and the class implementing the interface is not necessarily strong. For example, if we have a class called "House", that class could also implement an interface called "AirConditionin...
