What is inheritance?

Question

Accepted Answer

Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.

Inheritance allows code reusability and saves time and effort in writing new code.
The existing class is called the parent or base class, and the new class is called the child or derived class.
The child class inherits all the properties and methods of the parent class and can also add its own unique properties and methods.
For example, a class 'Animal' can be the parent class, and classes like 'Dog' and 'Cat' can be child classes that inherit properties like 'name' and 'age' from the parent class.
Inheritance can be single, multiple, or multilevel depending on the number of parent classes involved.
