In the field of object based programming, the concept of inheritance serves as a basic idea which enables classes to inherit characteristics and functions of other classes. 

It allows the development of a new class via inheriting the properties of a class that already exists, which is called the parent or parent class. 

A characteristic of various oriented objects programming programs that enables an object to inherit its methods and attributes from a number of parent classes called multiple inheritance. It's handy for building complicated structure of classes and reusing software. 

In this article, we will go through the principles of inheritance & multiple inheritance in Java in more depth, and we'll also present examples that show how they can be used.

What is Inheritance?

In the field of object-oriented programming, inheritance is a basic notion which enables types to inherit attributes and behaviours from different classes. 

=> It is an approach that supports the idea of "is-a" connections among objects and allows for reuse of code. The class structure has been constructed on inheritance, so classes may be organised in relationships between parents and children.

=> Inheritance is achieved by creating a new class, known as a derived class or a subclass, from an existing class, known as the initial class or superclass. 

=> The obtained class inherits all the characteristics of the lower class , including its attributes (data members) and methods (functions). This means that the subclass can access and utilize the inherited features as if they were defined within its own body.

=> One of the primary advantages of inheritance is the ability to create specialized classes that add or modify the behavior of the lower class . 

=> This concept is known as specialization or extension. The obtained class can add new attributes and methods or override the existing ones inherited from the initial class to suit its specific requirements. 

=> This flexibility allows for the creation of more modular and maintainable code The growth of more flexible and accessible code.

Example:

=> Take the "Vehicle" basic elements, which have traits like "colour" or "fuelType" along with techniques like "start" or "stop." 

=> We are able to determine specialised subclasses from this starting class, including "Car" or "Motorcycle." 

=> The vehicle class may inherit the Vehicle class's "colour" and "fuelType" features, in addition to its "start" or "stop" methods, yet it may additionally include distinctive methods of its own like "accelerate" and "brake." 

=> In a similar form, the Motorcycle class may inherit Vehicle's shared features and techniques while also having distinctive techniques including "wheelie" and "stunt."

Inheritance allows reuse of code, improves code organisation, and fosters modularity in computing. 

It allows programmers to generate a hierarchy of classes that effectively match real-world connections, making it simpler to create a more effective and stable software system. 

With that said, similar to inheritance we also have the function of multiple inheritance in Java as we have discussed in the next section of the blog.

What is Multiple Inheritance?

Multiple Inheritance is a language with an object-oriented programming feature that allows a single class to inherit includes and behaviours from numerous parent classes.

=> To put it differently, a class can inherit traits and techniques from various base types. The aim of this notion was to bring together the characteristics of different classes to create an entirely novel class having an expanded spectrum of ability.

=> A class that has been derived can inherit methods and attributes from any number of base classes in multiple inheritance. 

=> This enables developers to build a complicated hierarchy of classes and use code from multiple places. 

=> Because every initial class may provide its own collection of real estate and behaviours to the generated class, it's a powerful tool in writing adaptable modular code.

Example:

=> A programming language for computers which includes multiple GUI (graphical user interface) components and data capabilities is a prime instance of multiple inheritance. 

=> Imagine we have an initial class dubbed "GUIElement" which offers methods and properties for dealing with user interactions, and one named "DatabaseObject" that offers techniques for interfacing with a relational database. 

=> We can employ multiple inheritance to create a class that is derived named "GUIObject" that derives from the two "GUIElement" & "DatabaseObject." 

=> A created class would have been given accessibility to bothof the lower class ' functions and characteristics, enabling it to perform user interactions whilst also interacting with the database.

=> Another instance is a class structure for multiple types of cars. We might have a "Vehicle" foundational category that provides broad capabilities traits and methods across all automobiles, from which specialised classes like "Car" and "Motorcycle" are built. 

=> In addition, a different base type called "Electric" could include features and techniques relevant to electric cars. 

=> We may generate a class that is derived called "ElectricCar" which inherits both the classes "Car" or "Electric," integrating the characteristics of a standard car and an electric car through the use of multiple inheritance.

Now, as you might have noticed by now, there are several similar characteristics between inheritance and multiple inheritance in Java. Find out more about the characteristics of these functions in the next segment of the blog.

What are the characteristics of Inheritance and Multiple Inheritance?

Although multiple inheritance is strong, it may additionally complicate code architecture and cause disputes when multiple fundamental classes define an identical property or operation such as the Fibonacci java series. To deal with these issues efficiently, considerable preparation and layout are vital.

Inheritance & multiple inheritance are significant concepts in computing because they allow for reuse of code and encourage an adaptable and hierarchical design style. 

The capacity to inherit traits and behaviours from a different class, called a superclass or base class, is given by inheritance. 

This allows the development of specialised classes known as subclass or derivative classes, that inherit the superclass's common features and methods but also adding their own unique features. 

Inheritance improves reuse of code through removing unnecessary software, in addition to code organisation and upkeep.

Conversely, multiple inheritance relates to a class's capacity to inherit from many parent types. This lets a class include features from multiple places, enhancing adaptability and giving an effective method to create a complicated hierarchy of classes. 

When collaborating on domains that have numerous characteristics or when modelling intricate connections between things, multiple inheritance may prove particularly useful.

Winding Up 

Inheritance & multiple inheritance have both significant methods for increasing code extensibility, reliability, and reuse, allowing developers to create strong and adaptable systems for software that are capable of carrying out mathematical computations as well such as Fibonacci series in Java.
