Can abstract class have a constructor if so what is the use in C#?
If so what is the use? Answer: Yes, an abstract class can have a constructor. In general, a class constructor is used to initialize fields. Along the same lines, an abstract class constructor is used to initialize fields of the abstract class.
Can we create constructor for abstract class?
Yes, an abstract class can have a constructor in Java. You can either explicitly provide a constructor to the abstract class or if you don’t, the compiler will add a default constructor of no argument in the abstract class.
Why would you create an abstract class if it can have?
The short answer: An abstract class allows you to create functionality that subclasses can implement or override. An interface only allows you to define functionality, not implement it. And whereas a class can extend only one abstract class, it can take advantage of multiple interfaces.
Can we create object of interface in C#?
Like abstract classes, interfaces cannot be used to create objects (in the example above, it is not possible to create an “IAnimal” object in the Program class) Interface methods do not have a body – the body is provided by the “implement” class. Interface members are by default abstract and public.
What is the purpose of using abstract class in C#?
An abstract class cannot be instantiated. The purpose of an abstract class is to provide a common definition of a base class that multiple derived classes can share.
Why do we need abstraction in C#?
Abstraction allows making relevant information visible and encapsulation enables a programmer to implement the desired level of abstraction. Abstraction can be achieved using abstract classes in C#. C# allows you to create abstract classes that are used to provide a partial class implementation of an interface.
Can we create constructor of abstract class in C#?
Answer: Yes, an abstract class can have a constructor, even though abstract class cannot be instantiated. An abstract class constructor c# code example will be explained. For example in program, if we create object of derived class then abstract base class constructor will also be called.
Can abstract class have properties C#?
An abstract class not only contains abstract methods and assessors but also contains non-abstract methods, properties, and indexers.
