![]() This program will help you to learn how to use the Inheritance object-oriented concepts in your Java code. Now that we know what is Inheritance in Java and some specific properties of Inheritance, it’s time to see a real-life example of Inheritance in Java. What is Inheritance in Java Inheritance in Java or OOPS (Object-oriented programming) is a feature that allows coding reusability. While implements are used when some interface is there and some class wants to give an implementation of that interface according to depending on their requirement. Use extends when there is some class and another class wants to use the property of that class so always one class extends another class. Inheritance can be achieved in Java through two keywords: One interface can extend another interface in Java. In Java class never extends the interface rather it implements an interface.One class can implement multiple interfaces. Multiple inheritances are not supported in java but we can achieve this by using the interface.If a class implements Interface or extends an abstract class, it needs to override all abstract methods until it is not abstract.The constructor in Java is not inherited by the subclass.Default members can only be inherited in the same package subclass, not in another package.A private member of the super class can not be inherited in subclasses like private fields and private methods.One subclass can extend only one super class in Java but it can implement multiple interfaces.Here are some important points about Inheritance in Java which is worth remembering: It’s the Head First design pattern that taught me how to write flexible code using Inheritance and Polymorphism. These three books have taught me most of the object-oriented programming concepts I know today. The best way to learn object-oriented programming is following both Head First Java and Head First object-oriented analysis and design, followed by the Head First design pattern. Inheritance in Java is also used to provide a concrete implementation of abstract class and interface in Java. if a method expects a superclass object, you can pass a subclass object to it. it is normally used when some object wants to use an existing feature of some class and also wants to provide some special feature, so we can say inheritance has given the advantage of reusability.īy using Inheritance between Superclass and Subclass, an IS-A Relationship is formed which means you can use any subclass object in place of the super class object e.g. ![]() In Java, inheritance is defined in terms of superclass and subclass. ![]() In Java, we use the term inheritance when one object acquires some property from other objects. Along with Abstraction, Encapsulation, and Polymorphism, Inheritance forms the backbone of Object-oriented programming and Java. In other words, Inheritance self-implies inheriting or we can say acquiring something from others. Inheritance in Java or OOPS (Object-oriented programming) is a feature that allows coding reusability.
