Inheritance in object-oriented programming enables new objects to take on the properties of existing objects. A superclass or base class is used as the basis for inheritance. Inheritance is useful when classes represent an "is-a" relationship, when code can be reused from base classes, or when the same methods need to be applied to different data types within a reasonably shallow class hierarchy. It allows global changes by modifying a base class and types include single, hierarchical, multiple, multilevel, and hybrid inheritance. Advantages are reusability, extensibility, data hiding, and overriding while disadvantages include tight coupling between base and inherited classes that makes independent use and maintenance more difficult.

1. Inheritance

2. Definition
In object-oriented programming, inheritance
enables new objects to take on the properties of
existing objects. A class that is used as the basis
for inheritance is called a superclass or base
class

3. Inheritance is a good choice when
● Your inheritance hierarchy represents an "is-a"
relationship and not a "has-a" relationship.
● You can reuse code from the base classes.
● You need to apply the same class and methods to
different data types.
● The class hierarchy is reasonably shallow, and other
developers are not likely to add many more levels.
● You want to make global changes to derived classes
by changing a base class.

4. Types
● The different types of inheritance are:
-Single Inheritance:

5. -Hierarchical Inheritance

6. Multiple inheritance

7. Multilevel Inheritance

8. Hybrid Inheritance

9. Advantages
● Reusability -- facility to use public methods of base
class without rewriting the same
● Extensibility -- extending the base class logic as per
business logic of the derived class
● Data hiding -- base class can decide to keep some data
private so that it cannot be altered by the derived class
● Overriding--With inheritance, we will be able to override
the methods of the base class so that meaningful
implementation of the base class method can be
designed in the derived class.

10. Disadvantages
● Main disadvantage of using inheritance is that the two classes (base
and inherited class) get tightly coupled.
● This means one cannot be used independent of each other.
● Also with time, during maintenance adding new features both base as
well as derived classes are required to be changed. If a method
signature is changed then we will be affected in both cases (inheritance
& composition)
● If a method is deleted in the "super class" or aggregate, then we will
have to re-factor in case of using that method
