Abstract Classes and Methods

Is it possible to have an abstract class with a functioning method?

Hi Alex,

Yes this is one of the main differences between an interface and an abstract class. Just create it as a normal method:

Code:

public abstract class MyAbstractClass {

  // abstract method
  abstract void DoSomething();

  // normal method
  public string GetName() {
    return "John";
  }
}

If you do not have any functioning methods in you abstract class, you are better off making it an interface instead.

Abstract class-
"Abstract class is a class which can not be instantiated and can contain abstract or non- abstract method"

Abstract method- "A method without definition and without body.

Tips for this-
" Suppose pond is a class and fishes are method, If pond is dirty then it is not mandatory that Fishes are also dirty. If fishes are dirty then pond must be dirty.
