Before delving into the details of the “super” keyword, let’s quickly revisit the concept of inheritance in Java. Inheritance allows a class to inherit properties and behaviors (methods and fields) from another class, promoting code reusability and establishing a hierarchical relationship. The cla...
Interfaces provide a way to achieve abstraction and multiple inheritance in Java. Usage Interfaces are used to specify a set of methods that a class must implement. They are particularly useful for defining a contract that multiple classes can adhere to, ensuring that they provide specific ...
In this example, the Dog class extends the Animal class and implements the Pet interface, showcasing the combination of inheritance and interface implementation. Learn Java Essentials Build your Java skills from the ground up and master programming concepts. Start Learning Java for FreeGrow...
Testing:Final classes and methods might be challenging to mock for unit testing. Consider this while designing your classes. Inheritance:While final classes prevent inheritance, they can limit code reuse. Be sure to balance the benefits of code inheritance with the need for immutability. Thread Safe...
While inheritance enables us to reuse existing code, sometimes we do need toset limitations on extensibilityfor various reasons; thefinalkeyword allows us to do exactly that. In this tutorial, we’ll take a look at what thefinalkeyword means for classes, methods, and variables. ...

Inheritance is useful for code reusability: reuse properties and methods of an existing class when you create a new class. Note:From the example above; Thesuper()method refers to the parent class. By calling thesuper()method in the constructor method, we call the parent's constructor method ...
In Java, the super keyword is a reference variable that is used to refer to the immediate parent class object. It is particularly useful in the context of inheritance, where a subclass inherits properties and behaviors from a superclass. The super keyword allows a subclass to access members of...
