An interface in .NET is a reference type that defines a contract for classes to implement certain methods and properties.

• Interfaces contain method signatures but no implementation.

• Classes can implement multiple interfaces.

• Interfaces are used to achieve abstraction and multiple inheritance in C#.

• Example: public interface IShape { void Draw(); }

Data abstraction in OOPs is the concept of hiding the implementation details of a class and only showing the necessary information to the outside world.

• Data abstraction allows for creating abstract classes and interfaces to define the structure of a class without revealing the implementation details.

• It helps in reducing complexity by only showing the essential features of an object.

• By using abstract classes and interfa...read more

A static method is a method that belongs to the class itself, rather than to instances of the class.

• Static methods can be called directly on the class without needing an instance of the class.

• They are commonly used for utility methods that do not require access to instance variables.

• Static methods cannot access non-static members of the class.

• Example: Math.Max() is a static method in the Math class that returns the lar

Overriding is a concept in object-oriented programming where a subclass provides a specific implementation of a method that is already provided by its parent class.

• Occurs in inheritance when a subclass provides a specific implementation for a method that is already defined in its parent class

• The method in the subclass must have the same name, return type, and parameters as the method in the parent class

• Allows for polym...read more
