In this blog, we will learn about hierarchical inheritance in java followed by a basic introduction about oops and inheritance then types of inheritance, and then a proper explanation of hierarchical inheritance, and reasons to use hierarchical inheritance in java, working of hierarchical inheritance in java, at last, we will discuss the example of hierarchical inheritance.<\/p>\n
OOPs (Object-oriented programming ) is one the main or important concepts of any programming language like Java, Python, and C++. And because of this Java is one of the most useful languages in today\u2019s world. The oops has four pillars which are used everywhere in the oops and they are <\/p>\n
So in this part of the article, we will discuss inheritance. Inheritance is a property of mechanism in which an object acquires all the properties of its corresponding parent object. We use inheritance in order to avoid repeating the code if one object needs the properties of another class we can form a parent-child relationship between them and with the help of inheritance we can use the properties of the parent class. The class that is using the property of one class is known as the child class and the class whose properties are being accessed is known as the parent class.<\/p>\n
In java inheritance is mainly of five types, we will name all the types below and will study only hierarchical inheritance in java.<\/p>\n
Class:<\/strong> It is a set of objects that have the same properties or it can also be referred to as the blueprint from which we will create the object. When Multiple classes i.e, two or more than two classes inherit the same class it is known as a hierarchical inheritance in Java.<\/p>\n Code repetition is frowned upon in programming since it needlessly lengthens the code. It is required of a skilled programmer provides code that is both reusable and clean. One technique that allows for extensive code reuse is inheritance. In reality, utilizing a piece of code many times is made much easier by hierarchical inheritance. It’s time to talk about how hierarchical inheritance in Java functions right now.<\/p>\n We already know that in hierarchical inheritance in java multiple classes inherit from a single class or we can simplify it by saying there is one parent class and multiple child classes in the case of hierarchical inheritance in java. And you must remember that to use hierarchical inheritance in java there must be atleast two child classes.<\/p>\n The working of hierarchical inheritance in java is not very difficult as we just need a parent class and many sub-classes that will inherit the parent class first we need to create a parent class and then different child classes so that they can inherit from the parent class. It might sound a bit complex but it is not so let\u2019s now look at the examples of hierarchical inheritance in java to make the concept clear.<\/p>\n In this section, we will discuss examples of hierarchical inheritance in java We will discuss example of hierarchical inheritance in java and will explain the result properly with output and detailed explanation.<\/p>\n Code Implementation:<\/strong><\/p>\n\t\t\t\t\t\t
\nChild Class:<\/strong> The class which inherits from other classes.
\nParent Class:<\/strong> It is the class from which the child class inherits.<\/p>\nWhat is Hierarchical Inheritance in Java<\/h2>\n
