When would you want to use them? Mostly used for 'utility' functions.

http://letschattechnology.com/interface-vs-abstract-classes/. I think you should elaborate more your post to ensure it provides a proper answer to OP. You should be able to see that post now.

defined in 2 or more separate partial class As it currently stands, this question is not a good fit for our Q&A format. By adding this interface to Horse, all methods in IJumping should be implemented. Abstract classes are known as partial abstract classes whereas interfaces are known as fully abstract classes. Should be used when there is a IS-A relationship and no instances should be allowed to be created from that abstract class. Abstract class features are inherited by child classes whereas interface features have to be implemented in implementing classes. static class Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA.

making classes like Pony or WorkHorse which you like to be inheriting from Horse. We can write constructors in abstract classes whereas we can't write constructors in interfaces. Abstract classes support access specifiers whereas interfaces don't support access specifiers. A reason to do this might be to share only part of the source code to others.

Example: An Animal is an abstract base class where specific animals can be derived from, i.e. How should I deal with coworkers not respecting my blocking off time in my calendar for work? Suppose we want a horse to be able to Jump, an interface IJumping can be created. The IDisposable interface says that all classes implementing it will have a Dispose function.

StartJump and EndJump are defined), in Horse the implementations of these two methods should be added.

could not find so easy like that. An interface should be used to implement functionality in a class.

may not inherit, Static class: a class with only the basic logical difference is you create abstract class when there is a relation between two classes that will inherit the abstract class and you create interface for the classes which are not related to each other but do have some common functionality. "interfaces don't support access specifiers." Is the fact that ZFC implies that 1+1=2 an absolute truth?

Suppose you need some method to calculate the average of some numbers to be used in the Horse class, but you don't want to put that in Horse since it is unrelated and it also is not related to animals, you can create a class to have this kind of methods. If the reason is that the file gets too big, think about splitting the class in smaller classes first. Difference between InvariantCulture and Ordinal string comparison.

thanks a lot, Did anyone else click on this link?? What are Interfaces and Abstract classes in Java? In C#, what is the difference between public, private, protected, and having no access modifier?
