Inheritace

1. The idea of inheritance is to allow the creation of new classes based on existing classes.

   • When we inherit from an existing class, we reuse (or we inherit) methods and fields, and we add new fields and methods to meet the new situation.
     • Every time we find the relationship "is-an" between two classes, we are faced with the presence of inheritance.

2. Single inheritance: where subclasses inherit the features of one superclass. A class acquires the properties of another class.

   • Multiple inheritance: where one class can have more than one superclass and inherit features from all parent classes.
     • Multilevel inheritance: where a subclass is inherited from another subclass.
       • Hierarchical inheritance: where one class serves as a superclass (base class) for more than one sub class.
         • Hybrid inheritance a mix of two or more of the above types of inheritance
