Derived Classes

When we say a class is derived from another class, it means that it has all the fields and methods of the parent class and in addition to it, the derived class can contain additional fields and methods as well.

The syntax for making an inherited class is the following:

Here's an example with some concrete code:

In this example, Dog is the derived class, inheriting from the Animal base class. The Dog class has access to the Name property and the Eat method from the Animal class. Additionally, it introduces a new method, Bark, which is specific to the Dog class.

As illustrated in the diagram, there can be cases where a class inherits from a class which is already a class from some other:

In such a case, the class at the top-most level is called the Super Class. In this case Animal is the super class. Such a case where where there are multiple levels of inheritence is called Multi-Level Inheritence.
