In the realm of object-oriented programming, the concept of inheritance in Java stands as a cornerstone, empowering developers to build robust, extensible, and organized codebases. Java, renowned for its object-oriented principles, offers a sophisticated inheritance mechanism that allows classes to inherit properties and behaviors from their parent classes. This mechanism not only fosters code reusability but also promotes a structured approach to software design.<\/p>\n

Whether you’re a novice programmer seeking to grasp the fundamentals of object-oriented programming or an experienced developer looking to refine your understanding of inheritance, this article aims to serve as your comprehensive guide. In this article, we are going to study what exactly inheritance is in java and the types of inheritance in java that include single level inheritance in Java, multi level inheritance in Java, Hierarchical inheritance in Java, hybrid inheritance in Java. Along with that, we will study each case\u2019s inheritance program in java to clearly understand its working and output.<\/p>\n

What is Inheritance in Java?<\/h2>\n

Inheritance is one of the many features of Oriented Programming. With the help of inheritance, an object belonging to a class can inherit the functions and properties of another class. With the help of inheritance, the reusability of code is increased and code repetition can be avoided.<\/p>\n

Inheritance in Java can be performed when we create a class, the extend keyword integrates all the properties and functions existing in the included class.<\/p>\n

Terminologies to Know Before Learning Inheritance in Java<\/h3>\n

Class:<\/strong>
\nClass can be abstractly unit having particular properties and features and defined to create objects possessing the same properties and features. <\/p>\n

Parent Class:<\/strong>
\nThe Class whose properties and features are included in the newly created class or child class is known as the parent class. Parent Class must be defined already to be included in the child class. It can also be called a base class.<\/p>\n

Child Class:<\/strong>
\nThe class which gets the features such as properties and features from the parent class or base class is known as the child class. It is created with an extended keyword acquiring all the properties and features from the parent class. It is also known as a subclass, extended class or derived class.<\/p>\n

Types of Inheritance in Java<\/h2>\n

Now that we have a clear picture of inheritance in our that how it works and what inheritance in java is based on, we will move on to study the types of inheritance in java and also various inheritance programs in java for each of the cases. <\/p>\n

The fundamental idea of inheritance is the creation of a class with features of an already pre-existing class to increase reusability and avoid any form of code repetition or redundancy.<\/p>\n

The four types of inheritance that exist in java are as follows:-<\/p>\n

    \n
  1. Single Level Inheritance<\/li>\n
  2. Multi-Level Inheritance<\/li>\n
  3. Hybrid Inheritance<\/li>\n
  4. Hierarchical Inheritance<\/li>\n<\/ol>\n

    Single Level Inheritance<\/h3>\n

    \"\"<\/p>\n

    This is the most simple form of inheritance in java. In Single Level Inheritance, the child class inherits the properties and features of the parent class directly. <\/p>\n

    This scenario can be justified as the direct transmission of properties and behaviour from the parent class to the child class. The single-level inheritance program in java will help understand the working with more clarity.
